45 Super?

[flyandscuba]

Anyone using 45 Super in their G21, G30, or G36? Just wondering how the Glocks perform with it... If it works well, I might consider switching from 10mm Auto to 45 Super.

[Glock30Eric]

I have seen people saying it is doing very well with Glock. I have been considering about it. But first I need to build my experience with the reloading thing before I start working on 45 super.

[ArmyDoc]

Check on the Big Dawgs forum - there's a couple of threads there. Here's the longest: http://glocktalk.com/forums/showthread.php?t=197490

hmm, this is interesting. i was gonna get a 20 after the new year but i may just get some super barss and a new spring/rod.

[ArmyDoc]

That's essentially what I decided to do. Several people have reported 45 super loads that exceed 10mm in power.

I'm going to start reloading 45 super brass at +P+ levels. Should provide excellent margin of safety and push 230 JHPs at ~1100 -1200 fps.

[RWBlue]

Yes, I have a G21 setup for 45Super.

What should be understood is there is 45Super and there is 45SUPER. When I started there was very little reloading data for the 45Super so I went off book and made my own. What I ended up with is 45SUPER. Or to put it a different way, I pushed the ends of envelope.

If you are just wanting 45Super or 45ACP++P then it can be done with a standard Glock. If you plan on pushing the ends of the envelope then heavy spring, guiderod, new barrel, comp or suppressor is needed. If you continue to push the ends, it will beat up your Glock.

I am not sure what more to tell you. Oh, wait a minute.
1. If you are not a reloader, the 45 Super is not for you.
2. If you want to load to 454 levels, you will not get there with the 45Super.
3. With the bullets I tested the extra power of the 45Super is not realized because the bullets are designed for 45ACP and 45LC. A 260gr JHP bullet needs to be designed for the correct velocity before a 45SUPER will be a good hunting round.

im plannin on flat nose for hunting rnds at around those velosites, mabe a bit more.

[ArmyDoc]

I don't think you'll have any problem doing that.

The biggest problem is, as RWBlue said, there is little published reloading data. Hodgdon only lists up to 20,000 Cup. Not very helpfull when +P is 23,000 Cup, and I've been told Ace Custom who developed the round is loading at 27,000 Cup. There is no published maximum.

One thing that could help would be a 6 inch after market barrel - that would give slower powders a bit more time to act, which is supposed to help with heavier bullets.

It would be nice to have a reloading thread for 45 Super, similar to the threads on the 10mm Reloading forum.

[BOOSTED12A]

i have access to a chrono so after the holidays ill get some brass and the other stuff. the new barrel will be after ive experemented some.

[ArmyDoc]

That would be great! What powder/bullet combination do you think you will start with?

[BOOSTED12A]

probbaly 200grn flat nose FMJ. ive been loading with WSF so ill have to get different powder. ill post the results when i have some thing

[RWBlue]

That would be great! What powder/bullet combination do you think you will start with?

There is a good bit more data available online now than when I started. If you make a spreadsheet and add all the data you can find as well as the source, you can easily sort out the data that is not right.

Assuming you are doing the new barrel, compensator, and heavy spring. I would tell you can look at Rowland data also.

As always start a little low and work up. The limits with my setup is not going to get me a Kaboom, it will just beat my glock to death.

I don't have my load data with me, but from memory I think I had the best results from Power Pistol, AA#7 and Bluedot when I was pushing it hard.

As far as what bullet, that is a personal decision. I assume you are not loading for personal protection against people. (There is not much to gain over 45ACP+P) If you are loading for paper there are lots of options. I spent a lot of time working with Rainier PHP bullets in 185gr, 200gr and 230gr. They are cost effective for load development. The really light .451 bullets fly flatter. The 260gr Speer JHP bullets will feed, but will not open unless pushed VERY hard. The 300gr bullets are not recommended. I have some Hungarian 45ACP JHP. The bullets will not open at the factory speed. I always said I was going to pull some and load them to 45Super to see if they may be the ultimate 45Super JHP loads. I would also look at some of the bonded bullets because they should hold together better than the unbonded ones I was trying.

[ArmyDoc]

RWBlue,

I'm primarily interested in 230gr JHP at 1100 fps or so for deer, +/- hogs. This is about 10% faster than a factory loaded +p. Do you know of a JHP that will hold together at this velocity?

From what I remember.....
The best rounds were Rainier and Bonded Gold dots. The Rainier would become teardrops of lead and most of the lead would stay together. The Gold dot did a little better.

Gold Saber and other non-bonded rounds lost the jacket very quickly and then the lead continued through the gel like the Rainier.

In a totally different way....I really liked the Triton Quickshock. It dumped all its energy in the first 12 inches breaking the setup I had the gel sitting in. The bullet would break into 3 or 4 sections and head off in unknown directions sometimes exiting the gel. If I were to design an anti-personnel round this would be it. But they no longer make this bullet.

It is really too bad I lost most of these pictures. They were interesting.

From left to right you can see the bulge build. I was using a glock factory barrel, Star 45Super brass, and it wouldn't have take much to end up with a Kaboom. The KKM barrel is much better.

Bad pictures of the Triton ammo.

what were you loading that caused the case bulges?

[RWBlue]

Use data at own risk.
260gr Speer, AA#7, Standard Glock barrel.
10grs appears safe. Beyond that it gets questionable very fast. Fast enough that I was using a RCBS digital scale loading one round at a time and I wouldn't recommend it with a standard Glock barrel.

what velosities were you getting with the 10g?

[vaquero aleman]

I would like to ask the "dumb question". 45 Super can be shot out of a 45 ACP barrel? I don't have to buy a special barrel to put in my G21? Can 45 Super be bought online? It sounds like the people here that are shooting 45 Super are reloading and not buying the ammo from Midway or DT, so I guess that means that I need to find a local gun shop that will reload for me? And, since I will be recieving an LWD 45LTH soon, is the LWD barrel any better than the Glock 45 ACP for shooting 45 Super?

[RWBlue]

Sorry, missed this post.

IMHO, If you are shooting 45Super out of a standard Glock21 barrel, you are pushing your luck.

I don't know about the LWD barrel. For shooting 45Super it is all about support. If you look at the photo I posted above, I was shooting the 45Super in an unsupported barrel and I got bulge.

IMHO, If you are going to push the 45Super as hard as possible, you need a compensator.

I believe Buffalo Bore is loading the 45Super so you don't have to find a local person who may or may not be competent to load your ammo, but.......

IMHO,
1. If you want to shoot hot and heavy in a Glock.
2. If you don't reload
3. If you don't want to beat your gun into the ground
4. If you don't want a comp.
Get a G20. Most people are happy with the 10mm.

The G21 with special barrel with comp where you have spent a good bit of time slowly working up loads selecting the correct bullet is the most powerful Glock out there.

[vaquero aleman]

This is the beginning of my new-to-me Zombie Gun! I plan on starting off with 45 Super and then we will see what happens. At the moment, the only thing mod about her is the 6.61" LWD-21L45TH, a 22# Wolff recoil spring/guide rod and Wilson Combat recoil buffer. She came with Trijicon novac rear and standard front night sights. Now that I'm 49 and can't focus on the sights anymore, I think I'll be looking for some laser action. Isn't that just life! I trade for a G21, luck up and get an OD with decent sights and I can't see the bamn things anymore!

Since I enjoy asking these kinds of questions: Has anybody here chronographed Double Tap 45 ACP? I shot some DT 185gn Nosler and Winchester 230gn slowball out of my 6.61" LWD w/22# spring and the DT caused failure to feeds while the Winchester did not, leaving me, as usual, dazed and confused.

Dunno if this is clear enough or not, but does this show enough to say wether or not the LWD has the proper support?

[SDGlock23]

Yes your LW barrel has lots better support. I have a KKM barrel and 500pcs of Starline 45 Super brass, but haven't worked anything up yet.

Now THAT is badass.... :thumbsup:

[vaquero aleman]

Thanks! I think I might actually keep this one! Ordered me a 24# spring just in case the 22# don't get it done.

[vaquero aleman]

I just got back from the local shooting spot and I can say that things were not as I expected. I shot Buffalo Bore 45 Super 185gr JHP through the 6.61" and comp. I had to use my shooting discipline to get shots on target because it was quite snappy. As I do not have a chrony I have to assume that the velocities were what they were supposed to be. I shot about 14 rounds through the barrel/comp without any failures, then I removed the comp to guage the difference and started having failures. In dealing with the FTF's I could not focus on the difference between having or not having the comp. However, when I re-installed the comp, the failures stopped. And then I switched to the Glock barrel and shot some more, without failures, and I was very relieved to see that case bulging was minimal, so now I feel relatively safe having my G21 loaded with 45 Super. Will post pics later.

[PghJim]

Without the comp, you may need a stiffer recoil spring. What type of FTF were you having?

[vaquero aleman]

I would have to say the cartridges were taking a nose dive and failed to get pushed into the chamber. But then, it also seemed like the slide was just not getting pushed back far enough. I have a 22# Wolff recoil spring. There may be something to changing out the magazine spring for a stronger one like some folks have recommended.

Although, there was very minor bulging on the web area of the case and there is a strange indentation, which at first I thought was a crack, but it does not show on the inside of the case.

That is interesting. Is it more a scratch or cut than a dent. It is in the same place. Check the chamber for a ridge. Other than that I would have to say it is done during ejection. Don't know.

[vaquero aleman]

I think that it is being caused by the propellant pushing the brass into itself, like when a buildings supports fail because of overloading. I am pretty sure it only happened when I had the factory barrel in. Not very many are like that and I only shot about one mag through the factory barrel. I believe that I am going to buy the Jarvis barrel. I read a really technical sounding report, way over my head, that stated the 4140 chrome moly steel used by Jarvis is a superior steel in every way for a gun barrel. I found the report when I was googeling gun barrel steel. Actually it was 416 stainless vs 4140.

Mark a case with permanent marker. See if this is on the bottom or top or.....?

[vaquero aleman]

I forgot to mention that the Wilson Combat recoil buffer after only around 100 rounds has started to split in two places. They said it would be good for about 1000 rounds.

The ridge is higher on the bottom side of the case. It kinda seems like the upper portion of the case is being pushed into the lower portion of the case where there is no chamber support.

[RWBlue]

The ridge is higher on the bottom side of the case. It kinda seems like the upper portion of the case is being pushed into the lower portion of the case where there is no chamber support.

Do you have a way of checking the length of the unfired brass?
If it is too long, it shouldn't fit the chamber and shouldn't fire, but....?

I would also suggest measuring the unfired brass in comparison to fired brass.

I would also suggest shooting a standard 45ACP load to compare how the this particular brass expands with increased pressure.

BTW, I don't know what is going on, I am hoping that by measuring the brass, I will get an idea.

[vaquero aleman]

Unfortunately I do not have an outside micrometer. But I can say that it is new Starline 45 Super brass loaded by Buffalo Bore. I just ran another magazine through the Lone Wolf barrel and no problems, all smooth. So I am going to have to assume that the lack of support from the Glock factory barrel is causing the case to crumple just enough to leave a funny line.

http://i1163.photobucket.com/albums/q547/vaqueroaleman/Guns%20and%20Ammo/56-2.jpg

And there is an ever so slight bulge just under each line or "indentation", but not above the line.

I guess that we can call the unsupported area of the case the "subduction zone".

[vaquero aleman]

I sent an email to Underwood Ammo Co. and this was the reply:

Ronald,

That is definitely a round we will be releasing. We are currently looking
into test firearms for the 45 Super. May I ask what you use and if you know
of any drop in conversions for either a Glock or a 1911?

Just happened on this thread. I have shooting and working with the .45 SUPER in my 21SF for about a year. Here is my set up on my gun. I take no responsibility for your gun.
Lone Wolf 6" un-ported barrel,new Starline .45 Super brass. SS guide rod, un-cap. ISMI 22lb. recoil spring.
230gr. Rainier JHP. slugs 1100-1200+FPS with various loads. Fun round. Packs a wallop!

[vaquero aleman]

Well, I finally went "all in" and converted my G21 to 460 Rowland. But I seem to be having the same feeding issue, that I did with 45 Super, so I ordered an 11 coil magazine spring. If the extra power mag spring don't help then I guess I'll spend the money and get the $95 Sprinco Cor Bon unit.

I too have a 6" KKM barrel, 22# ISMI spring and playing with some .45 Super with my G21SF. I have been loading 230gr PD FMJ's and 230gr XTP's. Feed has been perfect with both the RN and the JHP's using stock 13RD and 10RD Glock mags.

This KKM barrel will not reliably feed my standard .45ACP 200gr LSWC's target loads that all my 1911's and stock Glock 21 barrels will do.

Ok, here goes. I started some 45 super load work using 45 +P Starline brass. I also purchased some 45 Super Starline brass as well. I cut some of each in half and felt the 45 +P brass provided more support.

Gun details: G21, Lone Wolf aftermarket threaded barrel, Wolf 24lb recoil spring. Stock otherwise.

The starting data used was lifted from this site:cool: I used Hornady 185XTP, AA#7, Wolf primer.

I'm at work and don't have the middle powder measurements however the first 5 shot string (left in picture) started at 13.0 grains and the 7th and final string (right in pic) finished at 15.5 grains.

My chrony was acting up all day and obtained some limited data. Shot string #5 (left to right in the box) was in the 1340fps range if memory serves correctly. Chrony messed up on 6&7 so I will have to redo those.

The gun functioned perfectly. Ejected cases went 5-6 feet to the right and slightly back. Recoil (in my opinion) was moderate-heavy.

I'm not seeing any smiles or any other indicators that would say to stop at this point. I've micrometered all of the cases the entire length of their bodies and I'm not finding any differences from string #1 to string #7 that would make me say "whoe nellie".

Please let me know your thoughts and what you would consider as a case head measurement that might make you take a second look. Question: Is this measurement vs a virgin unfired case or vs a starting load fired case?

Thanks for any input.

[dougader]

I think the ported or comped barrels help with the feeding issues. I think it helps to slow down your slide speed and lessens the battering a gun takes from the higher pressures of the 45 Super. I have a G21sf with a LWD 6 inch, 4-port barrel and a 22# recoil spring on a stainless guide rod. My rounds feed fine.

I don't have my notes in front of me, but as I recall I have loaded up 200 grain Speer "flying ashtrays" to around 1300 fps (these come apart like grenades at anything much over 1000 fps), 230 grain zero fmj's to right at 1200 fps, and the 265 grain WFNGC Beartooth Bullets hardcast slug to 1177 fps. You read that right. A hardcast 265 @ 1177 fps for 815 ft. lbs. of muzzle energy.

Now, my goal was to simply push a 255 - 265 grain hardcast slug to 900 fps; a ballistic duplicate of the old 45 Colt load from the 19th century. If you read about John Linebaugh's work with the 45 Colt, you'll see a 260 grain hardcast slug will penetrate antelope and mule deer from stem to stern. All I really need here in Oregon, unless I want to hunt elk or black bear with the 45 Super.

I worked up slowly to get to 1177 fps, and if I thought I really needed it again I'd do it. But I have backed down to my 1033 fps load as a more safe and sane use of my 45 Super set-up.

I still have a keg of the old Hercules Blue Dot, and it worked really well in the 45 Super for me. I haven't even tried other powders yet. Always use standard large pistol primers with Blue Dot. IME, Blue Dot can spike in pressure a lot faster when you're using magnum primers.

I am interested to hear how the G21 holds up to 460 Rowland.

Funny how I find myself back here. I believe that I will most likely be returning to the land of 45 Super. I am waiting, very anxiously, for Underwood Ammo to get some of thier new 45 Super in stock. I will be purchasing at least two boxes of his 230gr @ 1100fps to see how my 21 likes it.

Since I already have, in my mind at least, my 21 set up for 460 Rowland I think that it will probably shoot this 45 Super very well. Because, it did not like the Rowland at all! But then, I don't have a compensator to calm it down, just the Sprinco with the sub spring changed out for the Rowland and a 24# recoil spring. And, because I am a wild and crazy guy, I will be keeping my 21 loaded with the 460 Rowland 230gr @ 1300fps.

Sounds Cool V.A.!

Does anyone make a recoil spring heavier than 24lbs?

Sounds Cool V.A.!

Does anyone make a recoil spring heavier than 24lbs?

Ace Custom 45s shows on thier web site that they use a 25#. But I had no luck finding this 25# recoil spring. I guess it's a ghost spring.

I have searched Wolff, Sprinco, ISMI and probably a couple others but the highest they go is 24#. I have actually considered taking two springs, cutting them down a little and combining them to see how that worked, but I haven't ordered the extra springs yet. I think it has something to do with not haveing the money any more.

[Shaker223]

OK Thanks. You have covered all of the bases like me only I was unaware of the Ace spring.

They had some in stock yesterday.

PS - I am going to try a 24lb ISMI spring I got from Glockmeister the other day, have been using a 22lb version of the same up till now, just a little frame battering, not bad.

[vaquero aleman]

I think the ported or comped barrels help with the feeding issues. I think it helps to slow down your slide speed and lessens the battering a gun takes from the higher pressures of the 45 Super. I have a G21sf with a LWD 6 inch, 4-port barrel and a 22# recoil spring on a stainless guide rod. My rounds feed fine.

I don't have my notes in front of me, but as I recall I have loaded up 200 grain Speer "flying ashtrays" to around 1300 fps (these come apart like grenades at anything much over 1000 fps), 230 grain zero fmj's to right at 1200 fps, and the 265 grain WFNGC Beartooth Bullets hardcast slug to 1177 fps. You read that right. A hardcast 265 @ 1177 fps for 815 ft. lbs. of muzzle energy.

Now, my goal was to simply push a 255 - 265 grain hardcast slug to 900 fps; a ballistic duplicate of the old 45 Colt load from the 19th century. If you read about John Linebaugh's work with the 45 Colt, you'll see a 260 grain hardcast slug will penetrate antelope and mule deer from stem to stern. All I really need here in Oregon, unless I want to hunt elk or black bear with the 45 Super.

I worked up slowly to get to 1177 fps, and if I thought I really needed it again I'd do it. But I have backed down to my 1033 fps load as a more safe and sane use of my 45 Super set-up.

I still have a keg of the old Hercules Blue Dot, and it worked really well in the 45 Super for me. I haven't even tried other powders yet. Always use standard large pistol primers with Blue Dot. IME, Blue Dot can spike in pressure a lot faster when you're using magnum primers.

I am interested to hear how the G21 holds up to 460 Rowland.

I can say this; What I have learned from converting my 21 to fire 460 Rowland is that it is a very powerful cartridge. I decided to skip the compensator, in favor of a more compact handgun, and I have learned that though the 21 seems to be able to handle it, I'm not sure that I can.

I describe my 460 Rowland experience a little more in detail here:

Dougader,

Appreciate your load data and pictures of the WFNGC bullet... I am going to try that bullet out.

The Beartooth 265 grain WFNGC hardcast slug ...What dia. did you get... .451?

Thanks,

Jerry

[woodsloafer]

OOps!

[vaquero aleman]

Finally got some Underwood 45 Super on the way. 230gr Gold Dots @ 1100fps. I will see how my Sprinco likes that stuff. I just hope that my 21 doesn't get upset with me for switching up on it. I was feeding it 230gr @ 1300fps. I'm sure the frame will enjoy a little break from the pounding.

Hmm... 45Super 230gr @ 1100fps, ME of 618, PF of 253, dia. of .451, 12 rounds on hand(with double sprung magazine). What more can you ask for?

http://i1163.photobucket.com/albums/q547/vaqueroaleman/460%20ROWLAND/DSCN0515-1.jpg

I shot a box and a half of the Underwood 45Super 230gr Gold Dots, through my .460 barrel. And I was using my double sprung mags. The 1100fps ran like clockwork out of my 21. I believe that the slide stop never even touched the frame during the recoil. So the Sprinco, set up for .460 Rowland, couldn't stop the frame contact when shooting 230gr @ 1300fps but it worked perfectly when shooting the 230gr @ 1100fps. Who woulda thunk it? I think that I am going to have another conversation with Sprinco about this.

Any how. I believe that I have finally found a 45 caliber round that I can be satisfied with; The Underwood Ammo 230gr @ 1100fps Gold Dot. Shooting this ammo reminded me a great deal of shooting my old G20SF, really powerful but not too powerful and I even noticed a little flame coming out of the barrel. So now I really want to get some video of this ammo. Guess I'll have to order some more bullets.

[WeeWilly]

I shot some of the Underwood 230gr GD the other day out of my stock G21SF (with the exception of a 24lb ISMI RSA). The recoil seemed a little more jarring than my G20SF using a 22lb spring shooting 180gr XTP at 1295fps. I attributed the heavier recoil feel to the 24lb spring.

I got no frame battering at all with the 24lb spring. Feed was flawless. I am going to try the 22lb spring out of my G20SF to see if felt recoil will be a little more sedate. Cases were landing pretty close with the 24.

I really like this ammo. Definitely will be my new SD load for my 21/30's.

[SDGlock23]

Loaded up some .45 Super for the first time today. Used:
New Starline brass
9grs Power Pistol
230gr FMJ seated to 1.240"
CCI LP.

Only ran 5, it's terribly hot here, right around 100 degrees. Shooting Chrony F1 @ 10'.
Ran through Glock 21sf np3 w/4.6" KKM barrel and captured 22lb recoil spring. Recoil was there, but not brutal. Speeds were:
1095
1096
1092
1084
1078
Avg= 1089 fps/ 606 ft-lbs

Brass looked good, I feel there is some more room to play here.

[SDGlock23]

Little update, I loaded up a few more and to the backyard I went. G21sf w/KKM 4.6" bbl and 22lb spring.

230gr XTP 9.5gr Power Pistol, 1.230" (1.240" wouldn't feed in my KKM bbl), CCI LP, Starline brass. 5 shot average was 1135 fps packing 658 ft-lbs energy. Liking the 45 Super more and more! Brass looked good, I'm sure one could go a little higher still...slowly. Maybe 9.7gr next.

Also for kicks I wanted to give Longshot a try. I almost started at 10grs which is the minimum charge for 460 Rowland...but I prefer to play it safe. I only shot 3 of each, but here it is, this time 230gr FMJ @ 1.240" CCI LP Starline virgin brass.

8.5gr Longshot avg= 1025 fps

9gr Longshot avg= 1068 fps

The online data Hodgdon shows for the .45 Super is a joke, not even .45 ACP +P level. Brass looked okay and could more than likely go higher, but that's all for today.

Great data! It's great that you can shoot 45 Super through the Blackhawk convertable-makes it even more versatel. And once you get the cylinders modded right, being able to shoot the 460 Rowland is an added bonus.

[WeeWilly]

Man, it has to be nice to be able to shoot through your chrony in your backyard. I could likely do that once.

You are seeing a little better velocities with Longshot that I got. At 9.5 are you seeing any extractor rash or flattened primers?

Thanks for the link for the Blackhawk convertible information. I think, at least in the case of my G21SF in its nearly stock configuration (only an RSA swap), the pressure limits may be more about timing than absolute pressure limits. To my mind, there is no reason to believe that if my Glock didn't have to unlock, eject and reload it likely could withstand 460 S&W pressures.

[SDGlock23]

Living out in the country does have it's advantages :)

Yeah I am seeing a little bit of scarring of the brass via the extractor, nothing major but there's a little bit of bite showing. Primers did not flatten out with the 9gr Longshot or 9.5gr PP load however.

Gotta love those CCI primers.

At right around 1100fps with both BD and LS I start getting some extractor rash (and flattened primers, but I am using Winchester which are softer, I think if I were using Federal's they would be flatter than a pancake).

The extractor rash is not bad enough to cause problems getting it into a shellplate when reloading.

I saw your post on the KKM barrel. My KKM barrel does have a little more support under the ramp, but I think the chamber is very similar to my stock barrel, maybe a slight bit tighter, but still a lot of wiggle when I drop a round in and move it around with my finger.

I am going to pick up some CCI 350's this afternoon and give them a try.

I have been testing the Hunter's Supply 275 gr. cast FN bullet, and it's a dandy and my favorite thumper 45 Super bullet.

I'm shooting an XDm 5.25 (sorry), but I've run them up to 1060 fps. with Longshot and nearly that with Power Pistol.

I just sent some to an industry friend for pressure testing. I will post the results here if anyone is interested.

I built a 21 SF for .45 Super and I am having some problems.

The gun;
Glock 21 SF
5.75" Lone Wolf Barrel
Wolff 24# spring and Guide Rod
Recoil Buffer

The problem is it won't cycle the next round, sometimes it jams with the round still in the magazine but the bullet sticking up to catch the slide. And sometimes it doesn't feed at all, I have to manualy jack one in each time.

Chrony data;

185 gr XTP - 1373 FPS @ 3 ft.
230 gr XTP - 1213 FPS @ 3 ft.

Any help would be much apprieciated, I REALLY want this caliber to work, It is the ULTIMATE woods carry gun if I can make it reliable.

Hot stuff.

It sounds like your slide is out running the magazine. You might give one of those heavier wolff magazine springs a try. Getting some additional weight in the slide assembly might help as well. I am not very fond of comps, so when I have to cross this bridge some day, I am going to try a stick on wheel weight as a test.

Also, I had no luck at all with a buff, in .45 Super or with my G20SF.

[SickDick]

Thanks,
I think I will get the extra power mag springs and toss the shock buff and see what happens.

How did you set up your XDm 5.25 to shoot the Super? Are you using the stock spring or other? Apparently there is a 460 conversion for this gun using a ported barrel and stock recoil spring.

The only thing I've done is switch to a 22 lb. recoil spring and heavier mag springs.

I personally believe people take the recoil spring thing way too far. Super heavy recoil springs cause more problems than they are attempting to solve, and I honestly don't think they slow down barrel unlocking enough to help much anyway.

[NoJoy]

Ok thanks. Did you get the heavier mag springs from Wolff gun springs? Is the XD barrel fully supported? So this set up you have functions 100% with the Super ammo?

As I posted earlier, I had an opportunity to have a few loads pressure tested by a friend in the industry. This was a limited opportunity and I only sent 3 loads for testing in their pressure barrel. These were the top three loads I'd previously fired in my XDm 5.25. All used new Starline 45 Super brass and Fed 150 primers.

230 gr. LFN, Montana Bullet Works, 1.230" OAL
9.3 gr. Power Pistol, 1155 fps, 33,000 psi avg.

275 gr. Hunter's Supply cast, 1.240" OAL
8.3 gr. Power Pistol, 1035 fps, 37,000 psi avg.
8.7 gr. Longshot, 1063 fps, 40,000 psi avg.

These velocities are very close to what I obtained in my XDm so it's pretty safe to assume pressures are close to what was experienced in my chamber given that the pressure test barrel was 5".

I wish I could have sent a larger assortment of loads but we can extrapolate some data from this. I had hoped that the slightly slower Longshot might have given a bit higher velocities without a pressure penalty but that appears to not be the case, at least with this bullet.

Brother, these figures are good to know: I am about to purchace "another" G21 (as I sold mine some time back) and set up for the 45super.

To give you guys an idea here where you can take this...

In MY "G36" stock all the way little 45acp, I load WW/Starline plain 45acp brass, with a 230gr XTP, and 7.7grs of Power Pistol, and out of this little tube I am getting 907fps ! :wow:

Accuracy is like 100 rounds at even out to 35yds or so making a tennis ball size hole. It get plumb boring. haha.

Just saying all this to say that out of the 3.78" tube in a G36 with 7.7grs PP @ 907fps, the G21 with about 9.2/9.4grs PP in the AM barrel and 24# spring and good 45 super brasss should be a real sweet 45 ! ;)

Thanks for the test data and reprt here SDGlock23. If you find some other sweet loads PM me and load me up bro. ;)




Bless ya !

Good to hear from you brother, and yes I most certainly will let you know any new data I get for the .45 Super. I haven't loaded up in any .45 Super recently, but your post brought to mind that a few days ago I tested some regular .45 ACP using my trusty ole Glock 30sf. Similar to your numbers, with 7.7gr of Power Pistol I averaged 883 fps with a 230gr JHP loaded to 1.24" out of the 3.78" bbl...which isn't bad! The listed max is 8.1gr, although I haven't tried that... yet!

I think I will keep the 30sf stock since it still delivers good numbers, and stick to the G21sf as my .45 Super outfit. Good to hear you're getting one, they shoot so nicely, very easy to shoot and the .45 Super isn't bad at all, about like 10mm.

Take care brother, God bless you!

Yeh, I was really surprised to see these vels out of the little single stack G36, but very happy to get them. It is a very nice gun for carry in certain circumstances and places. I like the G30 as well. I sold my last one to help finance a S&W 629... ha

883fps is fine as well fro the G30. as Long as I can get 850+ out of a 230gr in my 45's I'm happy. That is plenty enough with the momentum of that 230gr hunk. ha.

Good wisdom in what your doing with the G30/G21. That is why I want to sell the G29 I have now and get he G21 back in my hands. I like the idea of the 230gr 45 at 1100/1200fps and has 13 rounds in one mag. ;)

What barrel are you using for the 45 super in the G21 brother? I got a LW in the G20 and it works great for savin brass life, but I must admit, the OEM works really well for me even with my hotter loads, just get the buldges, but all is well other than that.

I was telling a brother yesterday, that the 200gr .40 10mm at 1300, is nice, but I'll take the 230gr 45 at 1200 any time.

Stay in touch and let me know how the 45 super test and trials or going.


God bless you as well my brother !
Time is short ! ;)

Yes the .45 Super really shines and gives you big power and lots of rounds in the magazine. The barrel I'm using in the G21 is a KKM stock length one, it does have much better case support and works very well when shooting the Super. I use the same 22lb captured guide rod I do in the G20sf. It didn't feed some 230 XTP's loaded to 1.24", but I measured the factory Hornady version and they run around 1.23" and they fed fine. Something about the profile of the XTP that prevents it from being seated very long, at least in my barrel. It will feed to a longer OAL as long as the bullet is a little more rounded, like a Gold Dot or Golden Sabre, etc.

I've seen pretty good numbers others have posted using Blue Dot and 800x but haven't tried those yet either. There is load data out there for 250-260gr+ loads, which could be very interesting and hopefully I will get around to that. I might try some 200gr XTP's too.

Stay safe amigo.

Going to make this fast here, the wife was in a car wreck this evening, and we have all the insurance stuff out of the way and made all the calls etc, but I need to spend the evening with her and encourage her.. She is ok, but a bit bummed, it was her "brand new off the lot truck..." Just a few miles she had on it. Some guy up on the highway hit her in the rear. Damage is minimal, but it is a bummer to the mind and heart for her since it's brand new.. :crying:

Well amigo, yeh, PP should be and I think will be a real good powder in the super and bD as well.

My G36 and all my 45's eat XTP's real well, so maybe the KKM doesn't like em??? :dunno:

I load 45acp to 1.260 with the 7.7grs PP and 230gr XTP, and the OEM eats 'em, but they may have to be a tad shorter for an AM barrel. So some figuring out to do sounds like to work up some good loads and not have to seat to deep and raise pressures... Well rambling some brother. I got to much on my mind and best go right now..

I'll PM ya my email addres and we can jaw back and forth if ya want to... ;)


Jesus be with ya !

So I tossed the shock buff and got some wolff extra power mag springs and headed out to the range. I started with some .45 acp 230 gr. handloads, she ran good. Then I went to some 185 gr .45 supers, again ran good. Went back to some .45 acp's and things started to fall apart, wouldn't always cycle the next round again. Went back to the 45 super and she started jamming on the bullet. HELP! I need this gun to RUN BABY RUN.

[vaquero aleman]

I don't know if this will help you, but I had to use two standard mag springs in each mag for my 21. I had the same feeding issues with 45 Super and 460 Rowland. It did not fix the 460 Rowland but 230gr @ 1100fps runs like a charm with the doubled mag springs. I also run a Sprinco with an upgraded sub spring and a 22# recoil spring. It will feed 8 out of 10 on the 460 Rowland and feeds the Super with no problems. Good luck.

P.S. my "extra power" wolff mag springs are collecting dust.

[SDGlock23]

A little more data here. I wanted to mess around a little with 200gr bullets in the Super. All loaded to 1.220" using 200gr Speer TMJ, CCI LP primers and new Starline cases. 4.6" KKM barrel used in NP3 G21sf and captured 22lb RSA.

Temp was pretty hot, around 90 degrees but humidity wasn't that bad, I'm at about 1000-1050 ft above sea level. Loaded up three batches using Power Pistol. 10.5gr, 10.8gr, and 11gr. Five shot averages.

10.5gr PP average: 1209 fps / 649 ft-lbs
10.8gr PP average: 1241 fps / 683 ft-lbs
11.0gr PP average: 1278 fps / 725 ft-lbs

All brass looked good, primers were not flattened. All did have some extractor rash on them, but not severe.

I tend to prefer 230gr bullets when shooting .45 pistols, but the 200gr .45 is my next choice, I think the 200gr Gold Dot and XTP make for some good personal protection...and traveling out at almost 1300 fps doesn't hurt either! I don't have any 185gr bullets to test, as I'm not real fond of that weight in .45's but I may get a few to load up. I've seen those running around 1400 fps in the .45 Super for what it's worth.

I don't have any 185gr bullets to test, as I'm not real fond of that weight in .45's but I may get a few to load up. I've seen those running around 1400 fps in the .45 Super for what it's worth.



Very good info brother. Copied and stashed away for "that day" when I get my 21 back... (or another one i should say).

Nope, nothing wrong with 200gr GD's XTP's at those vels at all. Like you, I prefer the 230gr in all my 45's but am not opposed at all to using 200gr. Man even the 230gr are moving out plenty good enough. As I said, I am gettng 907fps out of my little G36 in 45acp OEM barrel with 7.7grs PP. :wow:

I need to send ya some 225gr Beartooth Hard Cast, and see what ya can do with those. I also got some Hunter Supply 200gr Hard Cast Pentagon HP's my friend at HS sent me to test in the 45acp. I would be interested to see what you get from them in the 45 super. PM me an address, and I'll send ya some next week when I can, if ya want to.


Thanks for the good info here brother..

Stay safe
God bless ya.

I'm still having trouble with my G21SF cycling the .45 Super rounds here lately. I have a 22lb. ISMI recoil spring, SS guide rod, LW 6" non ported barrel.
I got the Wolff extra power mag springs, still jamming. It will fire a round and then jam at the feed ram. I think it's the profile of the bullet I'm using. I have been using Rainer 230 JHP slugs. They have a SWC shape to the nose and may be causing the jam.
When I first starting shooting .45 Supers in this set up a couple of years ago, I was using Speer Gold Dots and Remington Golder Sabre. Don't remember that happening with those bullets, more of round nose profile. I'll try to find some of those scarce and more expensive bullets and see how they work.

I had the same problem until I finally managed to get two standard magazine springs installed into one magazine. The double springs provide far more power than the Wolff extra power springs. Unfortunately, I can only get 11 rounds in my mags but they feed the 230gr 45 Super I got from Underwood Ammo without problems.

[21Glock]

I'll try that with some of the mag springs I took out to put in the Wollf springs.

G21SF's firing one shot of .45 Supers aren't much good to anyone.

Thanks for the tip.

[21Glock]

BTW, are you running a 22lb. recoil spring in your G21 or are you using a 24lb.?
I have a 24lb. as well as the 22lb. one that I keep in there most of the time.

[vaquero aleman]

The Wolff recoil spring that I received had 24# printed on the label but I put it on a fish scale and I believe that it is a 22#. I also have a Sprinco with an up graded sub spring installed because my 21 is set up to fire 460 Rowland as well as 45 Super and ACP. Everything I have done to my 21 has been trying to get it to function with 460 Rowland and it has been a challenge. I finally, with the double mag springs, got it to feed 8 out of 10 of the 460, and I am not using a ported barrel or a compensator. Consequently I load my mags with the bottom 3 rounds 230gr @ 1100fps and the last 8 230gr @ 1300fps.

Hey amigo, I use 22# ISMI springs and a areo-tek SS rod in the G20/21. But, let me share this with ya. When I put the extra power wolff "mag springs" in, everything went south !!!

Same type issues your having. I put in NEW OEM springs (mag springs) and ALL was fine from then to now.

I know folks use them and no problems, i am happy for them, but I have always had issues with Wolff xtra power mag springs... Would never use them again.


Hope this helps in some way...


Good luck amigo !

Unfortunately, I can only get 11 rounds in my mags but they feed the 230gr 45 Super I got from Underwood Ammo without problems.


I managed to get two original mag springs into one of my OEM Glock mags that I'll use for the .45 Super rounds. Man, I see what you mean, it is STIFF, ought to keep the slide from out running the mag with this kind of pressure in the mags.
Looking forward to trying it out soon. If I can only get 7-8 .45 Supers in this mag I will be happy. Feed and function is what I need to turn this G 21SF into a great woods gun, along with my Gen 4 20 10mm.

[vaquero aleman]

Sounds great! I get 11 rounds in my double-sprung mags. Good luck.

[21Glock]

I had to use my OEM mag loader to the get the rounds to load into the mag. Real strong spring pressure with the double springs.
Hopefully, this should cure the jamming after I fire the first round. I'll be getting some more 230 gr. JHP bullets soon, more of a round nose profile this time.

I enjoy the .45 Super round too much to let the jamming stop me.

Where there is a will, there is a way, as they say....

[Cycletroll]

Warning: the following information is conjecture by a total amateur and may result in you blowing off your face! follow at your own Darwinian risk!

Over the last two years I have done extensive testing of hot loads out of my G21 (gen 3) with both the stock barrel and a standard (4.6") Lone Wolf barrel. I have also played around with lots of recoil spring combinations.
My opinion is that, up to the point you are edging into Rowland level pressures, the stock mag springs are fine. For anything more than +p level recoil a 22-24# spring is advisable. I think most people are having cycling problems at the upper end more from not holding the gun flat than not having enough spring. With high recoil and slide velocities unintended limp wristing results. Glocks are light and with high recoil impulse it is very easy to let the muzzle snap upwards which can lead to FTF problems.
I have duplicated many of the loads presented here as well as many with IMR 800x. ~1100fps with the Hunters Supply 275gr WFN is very doable with factory Win. brass and WLP primers and 800x.
The real issue with the G21 is chamber support (or lack thereof :) with the stock barrel. Hot +p or entry .45 super loads are all the brass will take (even Starline super brass) with the huge hogged out stock barrel. With a well supported chamber .460 Rowland level loads are possible with standard Win .45ACP brass. The issue with many aftermarket chambers is short throats. Sending JR at LWD your barrel with some dummy loads can result in more room to run longer COL and reduce pressure.
Longshot, Power Pistol, and 800x are the powers to go to. Blue dot gives decent numbers but gets peaky and will spike badly in cold weather. IMO it's dangerous for hot loads. If you use 800x or Longshot and work up slowly in the stock barrel you will get a very predictable increase in case head expansion at the six o'clock position. You can go much higher in a LWD or KKM barrel.
As many have noted, the G21 loaded with heavy hard cast is a fearsome woods gun. As far as I am concerned the Hunters Supply 275gr at about 1050 will do anything you need out of a handgun short of the great bears. This load shoots about an inch and to point of aim with my stock Meprolights and is well below max load for the gun and fairly mellow shooting. It sails through elk too ;)
The next evolution is to have the slide inletted and mount a Trijicon RMR so you have a handheld carbine with easy hits out to 150yds :)

[SickDick]

SHE RUNS, SHE RUNS!! I tried the 2 mag springs and all problems went away. I can get 11 in the mag and 13 with +2 mag extenders. I used 1 stock spring and 1 Wolff spring together in each mag, the Wolff springs are coiled a little different so they fit inside the stock spring. I am now thinking about getting some springs for the 25 round mags and cutting them to the necessary size to function and maybe I will be able to get 1 more round in the mag.

[21Glock]

I don't know if this will help you, but I had to use two standard mag springs in each mag for my 21. I had the same feeding issues with 45 Super and 460 Rowland. It did not fix the 460 Rowland but 230gr @ 1100fps runs like a charm with the doubled mag springs. I also run a Sprinco with an upgraded sub spring and a 22# recoil spring. It will feed 8 out of 10 on the 460 Rowland and feeds the Super with no problems. Good luck.

P.S. my "extra power" wolff mag springs are collecting dust.


Hey, thanks for for the tip on the double mag springs. I tried that today with my .45 Super loads and no JAMS. Not one. I only shot about 7 on one string of shots and three on another one. But, it quit jamming. Great tip to cure the jamming and keep the .45 Super's rockin along in my G21SF.

I'll keep this one mag rigged with the double springs for the .45 Super loads and my standard mags with one springs set up for my practice and SD loads.
Have you used a 24lb. recoil spring any with your .45 Super loads while using the double springs in your mag?
I'm using about 13.5 gr. of AA#7 behind a 230gr. JHP for around 1200 fps in my .45 Super loads. Definite difference from shooting hardball or standard .45 ACP rounds.

I ordered a Wolff 20, 22 and 24# recoil spring and eventually left the 24# installed. Being a man that trusts very few people, I bought a fish scale from Wal Mart and tested my springs. I believe that the 24# is closer to a 22#, but it does just fine. The double sprung mags were my last modification. But, you have to understand, I have been engineering my G21 to fire .460 Rowland. The 45 Super loads I have been shooting are from Underwood Ammo and they are 230gr @ 1100fps. The Rowland loads are 230gr @ 1300fps and as soon as Underwood begins selling thier Rowland loads it will be 230gr @ 1350fps. I eventually purchased a "Sprinco" recoil reduction system to stop the slide from destroying the frame. The Sprinco "Corbon" unit was not strong enough for the Rowland so I returned it to the factory and they upgraded the sub spring for Rowland. So when I shoot 45 Super it is more like shooting medium range 10mm loads. And when I shoot 45 ACP it is like shooting a BB gun. But I have also skipped the compensator which Johnny Rowland says is necessary to shoot his .460 Rowland. I have an LWD 5.2" 45 ACP barrel that I cut down to 4.75" and reamed out to accept .460 Rowland(.460 Rowland cases are 1/16" longer than ACP). It is really pushing the limitations of the G21 to shoot 460 Rowland without a compensator but that is what I have. With the compensator installed it is just too much gun to carry comfortably. I intend to, eventually, purchase a solid top long slide and 6.61" barrel from LWD and a Yankee Hill Machine compensator, but that is down the road a bit. I believe that with the 6.61" barrel I can get a 185 grain bullet to leave the muzzle at about 1700 fps. Or a 230 grain bullet at about 1500 fps. And if I start re-loading I might be able to attain 45 Winchester Magnum velocity. Pretty hot, no?

Thanks for info. I'll probably just use my 24lb. when I shoot .45 Supers, just to make sure I keep the slide off the frame as much as possible. Now that I have it not jamming anymore.
The .460 Rowland should turn your 21 into a real cannon!

[Shaker223]

Vaquero Aleman, did the factory give you any idea of the weight of the upgraded sprinco unit?

I'm having frame contact with a 24# Wolff spring. I'm pushing 185xtp's north of 1,350fps. The 21 cycles good...no issues.

I've been thinking of trying to modify a 1911 28# spring to see if that could help with the contact.

If your talking about spring weight, the recoil spring that they provide is 17# but the sub-spring is a different story. I use a 22# recoil spring with my Sprinco and they never actually told me what the weight of the sub-spring is, but my Wal Mart fish scale puts it around 35#. I originally purchased the Glock 20/21 "Corbon" model but I had to send it back to them and I told them my ammo was 230gr @ 1350fps and they said they would install a sub-spring that would handle that Power Factor. Of course the ammo that I purchased was from GA Arms and it is a 230gr @ 1300fps. As soon as Underwood gets it listed I will be buying my 460 Rowland from them, because it will be full power 230gr @ 1350fps, from a 5 inch barrel I am assuming.

I did not follow any rules in modifying my 21 to fire Rowland.

I am pleased to note, that in its present configuration, my 21 feels like I'm shooting 10mm when I shoot 230gr @ 1100fps. It handles 45 Super like most handle 45 ACP.

Sounds great! I would definately like to read about your results. I've pretty much only shot the 230gr in Super and Rowland so I don't have as much trigger time with the lighter stuff yet.

[Shaker223]

I finally shot my G21 with the new Sprinco setup. I marked the slide with a paint marker to see if there was frame contact and there was none. (I also put it in my G20 and it performes flawlessy there too)

I used previously loaded ammo that had 185gr Hornady XTP and AA#7. Velocities were in the 1325fps range. The cases and primers looked great with room to go up.

I would like to see if I can safely make 1400fps.

[SgtSchroeder27]

Hey guys,
Thanks for all your info on the 45 Super, I've been reading up on it and I decided to go in but I have a few questions.

What are the basic things to buy?

I have a Gen 3 21 with a Storm Lake threaded barrel already (looking at selling it to buy a 6" though)

Thanks!

[reflex264]

The 6" storm lake is the stuff. Mine shoots 10 shot 1" groups at 25 yards off of bags.

Think about your trigger as well. I am using a lone wolf housing with adjustable over travel stop, a 6#trigger spring, 3.5 connector, titanium safety button, polished factory striker and a siderlockt trigger. Mine is 1000X better than the factory trigger which greatly aids accuracy. reflex264

[Iceman cHucK]

About 4 years ago I spent a lot of time on 45Super in my G21 but could not get feed reliability. After reading this, the double mag spring may be the answer I was looking for. I have two LW barrels,one standard length and one threaded 5.3". I believe the extra chamber support is needed as I got too many smilys with the OEM Glock barrel. I used both the 22 and 24lb ISMI captured recoil springs. Tried the shok buffs but they quickly got cut up so I pitched them. Tried the Wolf Xtra power springs but thought they were worse! I concluded then that the slide velocity was too too fast for the mag springs to to catch up, resulting in nose dives into the feed ramp and mag. I was using BB 230s at 1100fps. Gary Hindman at ACE in TX told me they had to port the barrel to get the 45Super to work in the G21. He also gave me the spring specs to use in my S&W 4506, which has worked flawlessly in 45Super, and will still work 100% in 45+P and standard press 45ACP.

Double mag springs looks like the answer! Thanks folks, will give it a go!
Hey CanyonMan, Tu 45Super or not Tu do?

Also: re the XTP 230 bullets. Factory Hornady 230 XTPs have a shoulder on the bullet that would jam in the barrel lands on my LW barrels but not in the Glock barrel. To use these XTPs in the LW barrel, the bullets would have to be seated deeper, or ream out the barrel lands slightly so the bullet doesn't kiss them so hard!

[SDGlock23]

More data! I ran through an assortment of .45 ACP and .45 Super loads today. All shot from my Gen4 Glock 21 with 4 port KKM barrel (approx 5" in length). Listed .45 Super loads used new Starline brass and CCI LP primers. The velocities are averages.

10gr Power Pistol, 230gr XTP @ 1.260": 1177 fps (707 ft-lbs)

Previously I had loaded 9.5gr at a shorter 1.230" and got 1135 fps average out of my older stock length KKM barrel (4.6"), but it was also about 90 degrees outside, whereas with the data today, temps were around 50 degrees. My new KKM 4 port will accept XTP's loaded out to 1.260" (and longer, but I don't see going past 1.260") but my previous stock length barrel would only accept them @ 1.230".

My goal is 1200 fps with a 230gr JHP. If it was warmer out, I could have gotten it I think, but next up I'm going to try 10gr PP @ ~1.240-1.250". Brass looked good throughout all testing and I feel this is safe and should get me to, and even over, the 1200 fps mark. A note on bullets, I chose the XTP for several reasons. One I have more of them, and they're shorter than 230gr Gold Dots and I feel they might hold up the best at these speeds. The 230gr Gold Dot is definitely longer than the 230gr XTP, so loaded to the same OAL, powder charge would need to decrease, then work your way back up. I know it isn't scientific, but the 230gr Gold Dot @ 1175-1200 fps blows apart in water jugs, and I do mean completely blows apart, all the pedals sheared off except one what was barely hanging on.

On game, the Gold Dot probably wouldn't come apart quite as bad since water jugs have a tenancy to exaggerate expansion. Either way, the XTP and Gold Dot are my two go-to hollow point bullets for the .45 Super.

More data:
11.3gr Power Pistol, 200gr XTP @ 1.260": 1351 fps (810+ ft-lbs)
Very impressed with this, although it may be too much of a good thing. The biggest issue I see concerning the .45 Super (a problem made even worse in the 460 Rowland) is that I'm pushing bullets designed for .45 ACP velocities well above what they're "supposed" to be driven. This doesn't make it "bad", it just means that one should almost expect bullet failure. Just throwing that out there for thought.

The 200gr XTP and 200gr Gold Dot are very similar in length, and both are my pick for bullets most likely to hold together.

More:
9.5gr 800x, 230gr FMJ @ 1.260": 1080 fps (very consistent, extreme spread of 7 fps). I was uncertain of what to expect with this load, but it shot very well. Not the most powerful 230gr load, but still offers around 600 ft-lbs of muzzle energy.

8.5gr Power Pistol, 250gr hardcast Missouri "PinBusters" @ 1.220": 1101 fps (673 ft-lbs) This bullet is hardcast and although I prefer other designs, this one should get the job done, and they're inexpensive to boot.


I've been curious of ~250gr bullets in the .45 Super, and it's something I plan on playing with more. Next up I'm going to do 250gr Gold Dots ("Deepcurl")and I'm going to order some Beartooth 255gr WFN bullets. The 250gr Gold Dot is very long, but it will feed if I seat it to a max OAL of 1.210", which is right around the canalure anyways. Data is non existent so I will have to work up a load for it, but that's almost the case with any .45 Super. My goal is 1050-1100 fps with it.

The Beartooth 255 WFN is a very short bullet for it's weight, so that could be very interesting. I know a guy on here has loaded up the Beartooth 265gr WFNGC and got it up to ~1150 fps. My goal for the 255gr WFN is ~1150 fps from my 5" KKM barrel, that's more than enough for any critter I would use, and if I need more the 454 Casull comes out.

Also I plan on coming up with some VV 3N38 data as well, it's been very impressive in my 6" G24 bbl and I feel it could be awesome as well in the .45 Super.

[Cycletroll]

Try the Hunters Supply 275gr WFN. It is short and will fit in LW barrels. I've run it at 1100 fps. Works great.

[SDGlock23]

Thanks, yes I had looked at that bullet as well and have heard good things about it.

[SDGlock23]

Some more data I got yesterday, all velocities are averages and shot from my Gen4 G21 w/KKM 4 port barrel (5"). Temp was around 50 degrees. Brass is new Starline and I use CCI LP primers.

I am also using a captured 22lb RSA, I use the Glockworx adapter ring for Gen4's Glocks. It works like a charm on all my Gen4 Glocks in case you want to use gen3 recoil spring assemblies in your Gen4.

230gr FMJ, 9.8r Power Pistol @ 1.250": 1174 fps

250gr Gold Dot, 8gr Power Pistol @ 1.215": 1031 fps (8 fps extreme spread!!)

255gr Beartooth WFN (250gr), 8.8gr Power Pistol @ 1.175": 1125 fps


Notes: Previously the 230gr XTP @ 1.260 averaged 1177 fps, and my Precision Delta 230gr FMJ bullets are longer than the 230gr XTP. Next round will be the 230gr XTP loaded to 1.240-1.250 w/10gr Power Pistol.

All brass looked good. The 250gr Gold Dot load was a soft shooter for sure and I feel going 8.2gr PP is safe. A quick note, just like the 230gr Gold Dot, I don't feel the 250gr Gold Dot is meant for real high velocities.

It's been my experience that the longer pedal (usually heavier weight) Gold Dots don't hold up as well as the shorter pedal ones. An example, a 165gr Gold Dot from my .40 cal Gen4 G35 w/KKM 6" G24 barrel averages 1400 fps with VV 3N38, but held together very well and very uniformly in water whereas the 230gr Gold Dot in the .45 Super driven to around 1200 fps completely came apart. The 250gr Gold Dot is the same, I've driven it faster than it's meant to out of a warm .45 Colt and it too came apart.

I feel both bullets (230gr and 250gr Gold Dot) should be kept under 1100 fps. So after chronographing the 250gr Gold Dots, I loaded up one more with 8.2gr Power Pistol @ 1.210" and shot it into some jugs. Penetrated 4 jugs and did a real number on the first two and split the bottom of the third. I know, I know, water jug "testing" isn't really testing, but IMHO if it holds together in water, it will likely hold together in critters. If it penetrates deep in water, you can rest assured it's a deep penetrator.

I'm guessing the impact velocity to be around 1050 fps, here's a pic:

http://imageshack.us/a/img850/5391/supergolddots.jpg

Soft shooting, deep penetration, expanded to an avg of almost .80 cal and and 8 fps extreme spread. Looks like my quest for the 250gr Gold Dot in the .45 Super is complete. Oh, the shredded bullet in the background is a 230gr Gold Dot driven to around 1200 fps.

The Beartooth 255gr WFN is a nice bullet, although I had to seat it deeper than I really wanted, it's not so bad. The reason is that it's a very short bullet for it's weight, shorter than my 230gr bullets. 1.175" was the longest OAL it would chamber in my barrel. However, since it's so short, the base of the bullet isn't protruding any deeper into the case than any other bullet despite it's shorter OAL. Next up, I'm trying 9gr Power Pistol seated to 1.170".

[NoJoy]

How does the KKM barrel with comp handle the recoil with the Super? Does it make a pretty good difference?

[SDGlock23]

NoJoy, yes it does help out and certainly dampens the recoil. Not only does it help the recoil, but it seems to be a little easier on the brass. I think it along with the 22lb recoil spring slows the slide down enough compared to the previous stock length (4.6") KKM bbl, and as such, the brass doesn't have nearly the extractor bite on it as it used to.

[NoJoy]

Good to know thx! Can I get away with shooting the Super out of a Stock Gen 4 21 (with stock duel recoil spring) by just changing out the stock barrel for the KKM barrel with comp?
Sorry if you have already answered a simuliar question. :)

[dougader]

what is you overall length with the 265? Reflex264

1.185 - 1.186"

[dougader]

Dougader,

Appreciate your load data and pictures of the WFNGC bullet... I am going to try that bullet out.

The Beartooth 265 grain WFNGC hardcast slug ...What dia. did you get... .451?

Thanks,

Jerry

Hey Jerry, Mine is .451"

Yeap that will work NoJoy.

Ok thx appreciate it!

More fresh .45 Super data from Gen4 G21 w/4 port KKM barrel (barrel itself w/threading is 5" long)

New Starline brass and CCI LP:

230gr FMJ, 9.5gr Longshot @ 1.250": 1,185 fps (15 fps ES!!) That's 717 ft-lbs!

230gr FMJ, 9.8gr Longshot @ 1.250": 1,229 fps (37 fps ES) That's 771 ft-lbs!

"255gr" Beartooth WFN, 9.0gr Power Pistol @ 1.175": 1,179 fps (13 fps ES!) That's 772 ft-lbs (it really weighs in at 250gr, not 255gr)

"280gr" Beartooth WFNGC, 8.0gr Power Pistol @ 1.180": 1,065 fps (24 fps ES) That's 693 ft-lbs (it's a 275gr, not 280gr)

Notes: brass looked good on all loads. I had no previous data on the 280gr WFNGC, so I used 8.0gr. I feel 8.2gr would have been safe, even possibly 8.4/8.5gr. That should get me the 1100 fps I'm after, but I'm not disappointed since 1,065 fps is pretty close and it's still gonna kill quick and penetrate well.

[SDGlock23]

I'm going to load up some 200gr next with Longshot. I'm going to keep them a little below starting charges for the 460 Rowland, like above with the 230gr as the starting charge for the 460 Rowland is 10.0gr. Have I ever mentioned that Hodgdon .45 Super data is a joke?

[SDGlock23]

.45 Super w/200gr TMJ @ 1.225" (New Starline brass and CCI LP primers) average from 5" KKM was 1,310 fps. Not quite what I got using Power Pistol, but overall not bad at all.

[SDGlock23]

Too nice of a day to pass up! I had a few ideas in my head and wanted to see the results. Temperature between 55-60 degress outside and the gun is my normal, Gen4 G21 with KKM 4 port compensated barrel (5") with 22lb RSA (gen3). CCI LP primers and new Starline brass was used.

Working with Power Pistol and Longshot today:

250gr XTP, 8.5gr Power Pistol @ 1.190": 1,104 fps (20 fps ES)

250gr XTP, 9.0gr Power Pistol @ 1.190": 1,128 fps (38 fps ES)

250gr XTP, 8.5gr Longshot @ 1.190": 1,124 fps (12 fps ES!)

250gr XTP, 9.0gr Longshot @ 1.190": 1,164 fps (22 fps ES)

I like that the 250gr XTP has a somewhat short OAL, quite a bit shorter than my other 250gr HP, the Speer Gold Dot aka "Deep Curl". I was wanting over 1,100 fps and I got it, but was still curious as to how much, if any, it would expand at that velocity. I had to seat the bullet to 1.190" in order for it to chamber in the KKM, as 1.200" was just a hair too long, literally.

I think where the .45 Super/460 Rowland shine is not with .45 ACP designed bullets, although they can be pushed a little bit and still be okay. I think it's with the heavier 250gr+ bullets. Those bullets are usually designed tougher than ACP style bullets yet out of the Super/Rowland you don't have to worry about pushing them too fast because the bullets will take it. I believe the XTP is rated up to 1500-1600 fps, which you'll never see in a Super/Rowland.

Although unscientific, I loaded one up with Longshot and shot it into lined up water jugs and it penetrated to the 5th jug, shedding a little weight and coming in at 242.3gr, impact velocity over 1150 fps. Interestingly, with the same sectional density, a 200gr .400" XTP from a 6" .40 S&W will do over 1200 fps and also penetrate to the 5th jug. Both would be great choices on game. By comparison, a .451" 200gr XTP (.45 ACP designed) will do over 1300 fps from the Super, but only penetrates 3 jugs, although it did expand bigger, which is to be expected. Picture of the 250gr XTP:

http://imageshack.us/a/img708/4697/45super250xtp1175fps.jpg


I would have to say that I'm satisfied with a 250gr XTP leaving at over 1,150 fps, that's near 750 ft-lbs. To put that in perspective, that's as fast (or faster) than a .45 ACP 185gr +P and weights 65gr heavier, or the same speed as the 85gr lighter 165gr .40 S&W factory load.

[SDGlock23]

I've got some more .45 Super I'm going to work up, but in the meantime I found a nice little load for the .45 ACP. Shot from a stock Glock 30 Gen4 (3.78" barrel):

250gr Missouri RNFP "PinBuster" hardcast, 7.0gr Power Pistol @ 1.180": 910 fps avg, 3 fps extreme spread!

1.180 was the longest OAL that would chamber in the Glock barrel, I can load them a little longer out of the G21 KKM barrel but what I was looking for I found. And that is a load that packs a good punch, easily capable of dealing with most critters you would come into contact with in the woods, in the lower 48 at least! I feel this is a good solid load in a good carry-able package (G30).

Although I haven't tried them in the Glock barrel yet, the Beartooth 255gr WFN hardcast would be an even better option because 1) it's shorter than the Missouri RNFP and 2) has a larger meplat (flat nose) on it which is better if you want even more damage. As long as it cycled it would be a great choice too for those that only load for the .45 ACP.

Got some beautiful Hunters Supply 275gr FN hardcasts in the mail yesterday!

http://imageshack.us/a/img59/9605/45super275grhunterssupp.jpg

Very good profile, I can even load them to 1.260" too so that's fantastic. I loaded some up today with them, mainly just to get a base. My goal is 1,100 fps from the 5" KKM, and I'm essentially there, just shy but that's easily fixed. Here's what I have for now:

275gr Hunters Supply, 8.5gr Power Pistol @ 1.260": 1,078 fps (29 fps ES) That's a TKO rating of 19.1!

275gr Hunters Supply, 8.5gr Longshot @ 1.260": 1,075 fps (16 fps ES!)

275gr Hunters Supply, 9.2gr 800x @ 1.260": 1,075 fps (26 fps ES)

275gr Hunters Supply, 10.0gr Blue Dot @ 1.260": 1,009 fps (22 fps ES!)

I sure didn't expect Power Pistol, Longshot and 800x to give me almost identical results. What I'm going to do next is drop the oal to around 1.250" and with both Longshot and Power Pistol work some a 8.4gr, 8.6gr and even try 8.8gr.

Blue Dot did well, just not as well...likely needs more powder! However since there's really not any data out there most of this was just to get an idea of where to go next.

A few little things extra. For a good stout .45 ACP load, a week or two ago I loaded up 7.0gr Power Pistol under a Missouri 250gr RNFP "PinBuster" at 1.180". These are loaded at this OAL only because that's the longest that would chamber in the Glock 30 Gen4. This same load averaged 910 fps from the 3.78" Glock 30 and out of the 5" KKM today, it averaged 975 fps. That's a pretty stout .45 ACP, and honestly, I'm real impressed with this load. I suspect around 950 fps from the Glock 21. Very useful and very potent for sure, and it's caused me to have have a whole new respect for this ole warhorse of a cartridge, just fantastic.

One more. Probably the epitome of useless, but in case you have some 395gr Cast Performance WLNGC bullets laying around and a Ruger to shoot them in, from my 5.5" Bisley:

395gr Cast Performance WLNGC, 19.0gr H110 @ 1.720": 1,007 fps (22 fps ES!)

395gr Cast Performance WLNGC, 16.0gr Lil'Gun @ 1.720": 968 fps (18 fps ES!)

Not real fast, but it's almost 1oz of lead too. I'm sure I could drive it faster but I don't really see a point to it. Just another load that there is almost zero data for. I'm sure I with a 7.5" barrel one could get close to 1,100 fps. But my preferred heavy load for my 5.5" Bisley is:

330gr Beartooth WFNPB, 22gr Lil'Gun @ 1.625": 1,287 fps (29 fps ES)

BUT! This is a .45 Super thread and I'll have more before long.

[SDGlock23]

I ran a few more this afternoon, very pleased with them. Will post up soon!

[SDGlock23]

Okay here's the data from the other day. From Gen4 G21 with KKM 4 port barrel (5"). Using new Starline brass and CCI LP primers.

I've used Longshot before with good results, but wanted to try more of it in the Super. Anyways, here's what I got.

250gr Speer Gold Dot, 8.5gr Longshot @ 1.215": 1,122 fps (35 fps ES) That's 699 ft-lbs !

275gr Hunters Supply Hardcast, 8.8gr Longshot @ 1.250":1,137 fps (15 fps ES!) That's 790 ft-lbs! (20.1 TKO rating)

I've got faster with the 250gr XTP but it's shorter than the 250 Gold Dot, which is a rather long bullet. The 1.215" OAL is the longest that will chamber in the G21 KKM barrel, the profile of the 250gr Gold Dot is more blunt, as it's a revolver bullet first and foremost.

However, what I got above is plenty fast, they will come apart in a hurry if driven too fast. To add, I loaded up a 200gr Gold Dot over 10.2gr Power Pistol and while I didn't chronograph it, I suspect to be hovering around 1200 fps from the 5" KKM since 10.5gr got me 1210 from the 4.6" KKM I used to have.

Bullet experienced some failure though since it shed several pedals which tells me ~1200 fps is a touch fast but not overly so, and while I know water jug testing isn't the be all end all of bullet testing, it's a media that's somewhat hard on bullets. So while that doesn't mean it will for sure come apart in flesh and bone, if it stays together in water there's a good chance it will in flesh.

I would say 1100 fps is plenty for the 250gr Gold Dot (and 230gr Gold Dot too). I'm pretty sure there aren't very many animals walking around that a 275gr hardcast at almost 1150 won't sail completely through. My goal was 1100 fps with the 275gr, and I'm beyond that so I probably won't be doing much else to that load, it's more than enough anyways. It's 25gr shy of 300gr and packs almost 800 ft-lbs along with it. Should work quite well :thumbsup:

[Cycletroll]

SD,
Nice to see you having fun with hotrodding the .45 :)
Your workups are pretty much identical to the stuff I did a couple years ago with a gen 3 G21 with a stock length LW barrel. I really like Power Pistol, Longshot, and 800x too.
That 275 HS is a real thumper and I found it to be an awesome elk bullet at 1100fps.

The reason I posted was just to give a heads up about Blue Dot: Be Careful!
Blue Dot has a nasty tendency to pressure spike and can do so with temperature changes. I would not push Blue Dot as far as I would with the aforementioned powders.

Have fun and keep posting your results so we can make the 10mm crowd jealous :tongueout:

[SDGlock23]

Cycle,

That's for the heads up, Blue Dot isn't a powder I've really messed with too much even though I have a couple of pounds of it laying around. Some swear by it, but I've been tickled with Power Pistol and Longshot and will likely stick to those :) I do have some 3N38 too, which could be interesting but I would have to start the data since there is no data for 3N38 in the .45 Super.

I may try some more 275gr data using a few different powders, but I've met my velocity goal, well exceeded it really. I haven't looked too hard for it, but if I can find a 300gr hardcast with a good profile I might work up some with those, just for kicks you know. Now that you mention it, 10mm guys are strangely silent when the .45 Super (or 460 Rowland) is brought up!

[happie2shoot]

SDGlock23

Do you think these would be worty a try

http://leeprecision.com/6-cavity-452-255-rf.html

I have some cast and waiting to get my 460 barrel in the mail.
If you think they would be any good I will send you some, they are
250gr.

[SDGlock23]

Happie,

That looks like a good one to me, plus it says it will work in .45 Auto which makes me think the profile should work. The 250gr RNFP Missouri's look very similar to that, and they will cycle for sure. I'm not sure what OAL that Lee mould would work with in the Super, but the longer case of the 460 Rowland is especially beneficial for more blunt nosed bullets since the OAL of the 460 is the same of the .45 Super, which of course depends on bullet.

I've got some real blunt Beartooth bullets that I've had to seat kind of deep in the Super that would really benefit from the longer Rowland case since being blunt doesn't effect it as much. One day I may just break down and get a 460 barrel, but for now I'll have to be one of the few 45 Super guys :)

[Cycletroll]

Just so people are clear, the only function of the longer case in the Rowland is to prevent higher pressure loads chambering in .45 acp guns not rated for it. The COL between .45acp, Super, and Rowland are all the same, and thus, the interior powder volume is the same (barring slight differences from variations in brass thickness).
I have loaded Standard Winchester .45acp brass to Rowland level loads (In a strong gun with a barrel with complete chamber support and strong recoil springs)

One does not need a Roland case/barrel to make Rowland level loads. One does need good brass (Winchester, or Starline) and a strong barrel with excellent 6 o'clock chamber support and of course adequate recoil management system i.e. strong recoil springs and a compensator.
Buying a complete Rowland "kit" is a great way to get a "tested and approved" system for shooting .451 bullets really fast at high pressures. It is not the only way to do it.
The main benefit of only shooting High pressure rounds in a Rowland case is that they won't fit in any old .45.

[SDGlock23]

I've thought of this as well, since the cartridge OAL is the same, there really wouldn't be any real difference between the .45 Super and Rowland as long as the same OAL is used. I read an article about the 460 Rowland and Starline said 460 Rowland brass is made just like 45 Super brass, just longer.

I have read the article of using ACP cases to get 460 Rowland level performance out of a Ruger Blackhawk convertible, but I've not tried it using ACP brass in the Glock, since I do have a good bit of .45 Super brass. Starline does claim Super brass is stronger than .45 ACP brass, equally strong is the 460R.

My personal opinion has been that .45 Super brass is equally as strong as 460 Rowland brass. Some loads I've found do have to seat deeper than I prefer because they're revolver based bullets, which is why for those bullets the 460 can hold an advantage, but if the OAL can be kept the same on both, I don't see why the .45 Super couldn't handle a 460R level load in a comped gun with good support.
