Glock Addict: I also use the CCI 350 primers. I agree that the load doesn't need to be boosted any more. It might be safe to do so, but it is pretty hot like it is. I have worked up loads with other calibers and felt the need to push them until I found the limit and then backed off (38 super and 41 AE), and I feel the 10mm brass could safely handle more pressure, but I am content with it at the 12.4 gr load. I recommend anyone back off to 11.5 gr and then work up .2 grains at a time watching for over pressure signs. I still haven't worked on the 185 and 200 gr loads yet, but I will when I have time. I wish my work wasn't so demanding, I would do it tomorrow. I'm glad you tried this load. I think it will chrono to 1400 to 1450 fps in most guns. This is a real full house 10mm load and I think it is safe. I started using Hodgdon Longshot powder when I saw the little free Hodgdon load book and it listed loads for 40 S&W and on the list the Longshot surpassed the other powders by 200+ fps (if I remember correctly). I use it in several calibers now. It is very accurate.

Nice to hear from you again.

During vacation I got to test fire some of my Longshot loads, and I was well pleased. I haven't done a lot of chrono testing, but it seems I can equal or surpass my Power Pistol loads, with less pressure. Oh yes!, much less flash also.

Didn't do much in the way of accuracy testing either, but it does seem to shoot to point of aim, (very important when using fixed sights), and also seems to shoot fairly clean.

I believe 2007 will be the year for 10mm and Longshot experimentation. Now if I could just find that empty brass.

Flattened primers on that second load with 8.9gr HS6. Load was .5gr under max. Use with caution.

Years ago, I decided to mess with HS-6 in the 10. After a lot of study, I decided that HS-6 SHOULD have the perfect burning rate for the 10mm.

Then, I searched through all the loading manuals and found that NONE of them gave as heavy a load or velocity, as what I thought they should give, considering how HS-6 compared to other similar powders. I tried a few test loads and found some similar stuff to you.

Bottom line is that HS-6 will give about 80% of the performance of other powders, and does not live up to anticipated expectations considering its location in the burning rate chart. It's just one of those quirky situations where it doesn't work out...

HS-7 on the other hand...

I'm picking up Longshot while in Green Bay this weekend. I'm going to burn up the rest of the HS6 in 45 Auto.

I've been loading 165gr plated bullets with 9.2gr of longshot, OAL 1.26" with winchester WLP primers, I cant see any deformation but can feel the case head is bulged while resizing.

would it be safe to go up to 9.9 grains or do i really need to work up to it?

I am using an autodisk and that is the only jump without weighing every charge.

or should I load 10 at 9.5gr, 10 at 9.7gr, and 10 at 9.9gr?

What is the water's method or recognizing overpressure?

Farther up, there is a load of 10.2gr of LS, but it is a different primer, I may have answered my own question, but if anyone has interjections to add, they're welcome!

Thanks.

Hodgdon Lil'Gun Works in the 10mm!

I have already posted this, but I wanted to put it in the Hodgdon Powder data sticky so that people would know where to look.

THESE DATA ARE NOT FROM A RELOADING GUIDE. YOU ASSUME ALL RESPONSIBILITY CONCERNING YOUR USE OF THESE DATA.

After much theorizing, I decided to load Hodgdon Lil’Gun in the 10mm. My starting loads were based on a number of factors:
--maximum working pressure for the 10mm (which, at 37,500, is lower in practice than some people realize);
--Hodgdon’s various Lil’Gun loads for the .327 Federal, .38 Super, and .357 Magnum;
--total grain capacities of the 10mm and the above calibers; and,
--my experience with the 10mm’s slowest recommended powder, Accurate #9.

These factors do not add up to an ability to perfectly predict the outcome. But I am happy to note that not only was I able to complete the testing safely, but I came up with some rather promising results.

Components:
--Hornady 180 grain XTP bullets;
--New Starline brass;
--CCI 350 Magnum Pistol Primers.

Everything I read about Lil’Gun indicated that it requires a magnum primer and a heavy crimp. In preparing these loads, I seated and lightly crimped the bullets with a conventional seating/crimping die, then immediately put a heavy-duty crimp on them with a Lee Crimp die. I did the initial crimp before the heavy-duty crimp because some of the charges were slightly compressed. Incidentally, while Hodgdon has warned in the past that Lil’Gun should not be compressed, in the 2009 Hodgdon reloading manual Hodgdon published a compressed Lil’Gun load for the .38 Super. I loaded all cartridges to just under 1.260".

As a baseline, I fired two strings of high-power Accurate #9 loads on the same day as the Lil'Gun loads. All strings were fired in the same pistol, my Colt Delta Elite Gold Cup. I used a 24 pound Wolf recoil spring, coupled with the original recoil spring plug, which incorporates a smaller, secondary spring. My Delta Elite does not have a fully-supported chamber.

These results are quite promising. The fired brass and primers looked very healthy. As noted earlier, I fired these in a pistol without a fully-supported chamber. While I often see “Glocksmiles” (even though it is a Colt) when shooting high-power 800-X loads, there were none to be found from the Lil’Gun loads. An average of 1293 is nothing to write home about, particularly considering the 1400 fps average in the 15.5 grain Accurate #9 load. But the fact is that Lil’Gun works in the 10mm! I don’t have time right now, but I am interested in moving up .5 grain to 1 grain.

I hope that this information is valuable.

New Data--Serious Velocities

As with my earlier post, I have already posted this, but I wanted to make sure that it was placed in a sticky.

The new data are interesting and a little confusing. Once again, I used 180 grain Hornady XTP's, new brass, handloaded each charge, and put a heavy crimp on the cases. As you can see, the 17 grain charges were slightly faster than the 17.5 grain charges.

What is frustrating is that the highest average velocity (1395.7) is actually lower than the highest average velocity using Accurate #9 (1400.9). But the maximum velocity with the Lil'Gun loads was higher (1434) than the #9 loads (1417). I will probably experiment with using a slightly lighter crimp and dropping down by a few tenths of a grain. It may be that compressing Lil'Gun in the 10mm doesn't do any good. Compression loads work for some powder/cartridge combinations, and not for others. I will also try to load them just a little bit longer, but the need for reliability dictates that I only stretch them by a few thousands of an inch, so it may not make any difference.

Very interesting data indeed. 180g @ 1400 fps ain't no slouch!

More Data

Just placing this in the sticky.

Here are some more data for Hodgdon Lil'Gun in the 10mm. For this set of tests, my protocol was essentially the same: new Starline brass, CCI 350 magnum primers, hand weigh each charge, et cetera. I tested some slightly different powder charges and used both standard and heavy crimps. I also fired a string through my Smith & Wesson 610. Some of the strings do not include 10 shots because I got some sunlight-related error readings.

Ultimately, I am disappointed with Lil'Gun in the 10mm. Of course, I never expected world-shattering velocities. But I was hopeful that I would see very good velocities with good shot-to-shot velocity consistency. Unfortunately, the consistency is terrible. Lil'Gun is the superstar in the .357 Magnum and is great in many magnum cartridges. It just doesn't look like the right propellant for the 10mm. It may be possible to get great velocities and consistency in the Smith & Wesson 610 by loading the cartridges longer than 1.260". But in the automatics, you usually can't do that and expect reliability.

If someone has success with Lil'Gun in the 10mm, or even an interesting theory about what to try, please post it.

Hodgdon Longshot, 9.7grs
175gr Winchester Silvertip HP
Starline Nickle 1.260" Fed 150

Stock Glock 20
85 degrees with skin melting humidity
Shooting Chrony F-1

Avg= 1365 fps - 724 ft-lbs

Ever so slight Glock belly, nothing abnormal at all. This load frags like mad when fired into water jugs. Jacketing was found in 2nd and 3rd jugs, 3 jug penetration.

10.2gr of Longshot, under a Nosler 170gr JHP (no longer made).

New Nickle RP brass
WLP
Wilson Combat CQB
Rainy and 45 degrees, 1200ft elevation.

Average 1392 fps.

A pretty hot load, with 5 of 10 casings bulging/smiling. Primers are pretty flat. I would not recommend this load, as the over-pressure signs are significant. Probably 10gr is tops, 9.8 for a Glock stock barrelled gun.

My first light practice load.
Stock G-20
165 Rainier plated TC/FP
1.272" COL
R-P nickel brass/CCI 300 primers
5.3 grains Titegroup
1,001 fps.
Two failures to extract-slow slide velocity I'm sure.
Excellent accuracy though, puts my G-21 to shame.
My chrono (Shooting Chrony F-1) seems to read consistently about 50-75 fps fast, for example CCI Blazer 200 clocked 1,050, which is faster than most results I've seen from a stock G-20, other calibers are the same way.
I'll edit this post as I work this load up, but I couldn't find any Titegroup data for the 165's, so I thought I would post.

I am really happy with the consistency of the 8.2gr load, which is Hodgdon's listed max. I have 2k WLP's on the way, and I may pick up some CCI350's to see if that will help kick up my velocities. With a 1247fps average for a 200gr bullet, there's nothing really to complain about. But as always, I want more...

I am pretty happy that 8.2gr of Longshot load beats DT's factory loaded 200gr WFNGC's out of my gun. Here's what DT's ammo did out of my G20L the same day:

Nice report. Thank you for the nice information. Longshot has been one of those powders I have never gotten around to. Yet more evidence that I should pick up a can.

Here's some more Longshot data, this time with Mag Primers.

Hodgdon Longshot
DT 200gr WFNGC
Starline Brass
CCI350 Primers
1.26 OAL
6" LWD Barrel
Wolff 22# Spring
85* F, Sea Level

8.0gr Longshot/CCI350:
1247
1238
1245
1239
1230
Ave: 1240
ES: 17

8.2gr Longshot/CCI350
1262
1249
1229
1250
1255
Ave: 1249
ES: 33

8.4gr Longshot/CCI350
1243
1285
1250
1267
1278
Ave: 1264
ES: 42

Primers are starting to look more flat, but I think there's still room to grow. I'm still hoping I can average 1300fps with the 200gr WFNGC's out of my G20L with good precision.

180gr XTPs Longshot

brand new to 10mm reloading, just tried out my new LWD G20 longslide with 6" KKM barrel for the first time.

more details:
22# Wolff recoil spring.
virgin starline; 180gr XTP @ 1.260 OAL; CCI 350; Lee FCD 1/2 turn
each powder load trickled/weighed by hand
indoor range, CED M2 chronograph with infrared lights 10ft from muzzle.


LONGSHOT
9.2gr:
1339 1345 1334 1343 1333
(avg 1339fps; ES 12; SD 5; 717 ft-lbs)

9.5gr:
1373 1387 1366 1372 1388 1386 1387 1381 13374
(avg 1379fps; ES 22; SD 8; 761 ft-lbs)

9.7gr:
1398 1397 1416 1401 1398 1392 1404 1383 1408
(avg 1400fps; ES 33; SD 9; 782 ft-lbs)


Im pretty happy with these results. from reading prior posts i wasnt expecting velocities this high. also tested some rounds with blue dot and 800x. im most impressed with 800x

The more powder I added the velocity never really went up. This speed of powder with the heavy 200gr. bullets is at it's limit at 1170-1180 fps out of the standard length barrel.

My experience is that I need to go to a slightly slower burning powder to get a little more velocity. Using max loads of LongShot with the 200gr XTP I still had about .090 gap between top of powder and base of bullet which tells me I can and should go with a slower powder (takes up more room). I prefer 98%-100% load density.

My next powder to try for this 200gr XTP bullet is 13-13.5 gr. of AA#9. I hear it meters well and load density should be perfect. CCI Mag primers will be used. Looking for a goal of 1200 fps.

If your happy with 1170 fps from a 200 gr. projectile, I would say LongShot is a great powder. Meters very well, burns clean with mag primers and is the only choice I would use from Hodgdon in the 10mm with heavy bullets. I hear HS7 burns dirty which is not what I want when I'm shooting 300 rounds in one day at the range with tight clearances on a KKM barrel.

Still can't wait to reload using AA#9.
The only powder I use for the G20 with the 200 grain XTP is AA#9 I would start with 12.5 grains. I backed off from 13.0 and 13.5. 12.5 grains seems the best bang for the powder. I did not find much velocity improvement over 12.5 of AA"9 in a Barstow barrel.

Merry Christmas! Nice report Wavesport! I've got some 9.6 & 9.8 grains Longshot, loaded in new Starline Brass, 1.258 OAL, CCI 350's and Speer 180 TMJ's to shoot either today or tomorrow. Loaded these on my NEW XL650 Dillon (thanks to my wife!) I'll post data soon.

~9.6 Grains Hodgdon Longshot (Dillon XL650 dropped charges - charges plus 0.2 grains in some cases or 9.8 grains)

Speer 180 Grain TMJ

95%: ±29.1

(End Of Data)

Seeing significant high pressure signs - smiles, flattened primers and headstamps. Loaded over 100 of these on my Dillon, but after shooting about 20 rounds, I decided brass was looking too stressed. I'm going to back down to 8.0/8.2 grains of Longshot with same bullet, primers, brass OAL etc. next. I'm hoping to achieve ~1250 - 1300fps with a 180 grain TMJ bullet.

I found 9.6 Grains of Longshot to be pushing what I'm comfortable with loading in my 10mm Glock 20. Smiles with primers and headstamps flattening. Nice velocities for a 180 Grain bullet, but IMHO seems to be at case limits - those cases are no longer in the reloading pile. The 8.2 grains of Longshot seemed to perform about as expected. I'd like to get 1250~1300fps, so an increase to 8.4 grains may be the ticket. Cases looked fine with the 8.2 grains of Longshot and appear to have room to grow.

These loads were done on my Dillon XL-650. Velocities obtained from a CED M2 Chronograph with Infrared Screens.

Hope this data is useful. Have a Happy and Safe New Year!

Stock G20 Longshot

Picked up some longshot and would like to do a little reloading while awaiting new barrel, spring, etc.. Out of a stock Glock 20 what would be the starting loads for 155 XTP and 180XTP using longshot. Experienced reloader and will take any and all advise at my own risk. Many thanx
