I take it the accuracy remark dealt with the 200gr. XTP.

What kind of accuracy did you get with the 180gr. XTP @ 10gm 800X?

What is your most accurate 180gr. load?

Thanks
Jim

P.S. I am thinking little parachutes for the ejected brass would be good. Mine goes 15 to 20 feet from my EAA Witness. I like the all steel feel at these levels.

175gr Silvertips

First time working with 800X and I like it, seems to soften up the muzzle flip.

G20 6"KKM, Win 1x, WLP, 10.1gr 800X, COAL 1.258", 90F, 50%+ RH (monsoon coolness with more humidity), 4200ft:

1398fps MV, 759fpe ME, ES 37fps, SD 13fps

No primer or extractor marks with 22# Wolfe spring; however, the steel recoil rod drops down one notch on the KKM barrel and I don't know why.

My steel recoil rod drops down a notch on my factory and stormlake barrels. I'm pretty sure the factory rod does too. I just thought that was normal.

Lenny, do you have any idea what the pressures are in that 10.5gr/800x are running? It's got to be something like 45,000psi. Time to start looking into a .41mag maybe??

Witness Steel Fullsize 10mm

Finally got out to the range with the new chrony.

It worked well but I found I had to put it about 15 feet out so MUZZLE blast would not read....had a coulple of readings around 2200fps would be a nice veloctiy though for a 200 gr XTP out of a 10mm :blink:

These were all individually thrown charges then trickled off to get exact measurement.

Anyone trusting 800X through a meter and not weighing every single charge is asking for SERIOUS trouble......some of my thrown charges were 1 gr more than the average!!

Anyways here we go.

Witness 10mm Steel Fullsize(factory barrel)
Starline brass(new)
200 gr XTP
Imr 800X
1.258 OAL
CCI350(MAGNUM PRIMERS)
Lee Factory Crimp die(light crimp 1/2 turn)
43 degrees cold and windy.

8.8 1168(HI) 1103(LOW) 1132(avg)

8.9 1196 1119 1142

9.1 1174 1145 1160

9.3 1189 1149 1163

9.4 1203 1158 1173

9.5 1218 1182 1200

9.6 1228 1181 1210

None of the cases had any flattened primers. No excessive bulging either. I may try a .1 or .2 gr more but my absolute max will be 9.8. As stated before Mcnett's 10.0 gr load was in excess of SAAMI max and I will not even try it.

I fired off a total of 50 shots most grouped in about 3 inch circle 2 inchs above Point of Aim.

Still have a few FTF but this has greatly improved with tweaking of magazine mouth.


Witness 10mm Steel Fullsize(factory barrel)
Starline brass(new)
200 gr Montana Gold CMJ(complete metel jacket)
Imr 800X
CCI350(MAGNUM PRIMERS)
1.258 OAL
Lee Factory Crimp die(light crimp 1/2 turn)

I started this load off at 8.0 gr. but never chronoed it until 9.6.

9.6 1180(HI) 1173(LOW) 1178(AVG)

9.7 1225 1179 1203

9.8 1233 1183 1208

I had better cycling with this bullet and once again no flattened primers or excessively buldged cases. I may try 10.0 gr in this bullet because quite a bit shorter than the XTP.

This is my first experience with Montana Gold and they seemed to work fine at near maximum loads. Accuracy and grouping was much the same as the XTP.

I thought I might get a little better velocity than these numbers because I think the stock barrel on a Witness is actually 4.75 inchs which is slightly longer than on the Glock 20 factory barrel.

The lack of performance was probably due to colder temperatures?

The Lyman #55 dispenses 800X consistantly, just use a shallow setting for drop rather than a deep setting. I still measure individually on workups, but I found 800X consistant enough to measure every ten rounds for inventory; which is almost gone.

I may have some 200XTPs left so I'll try your recipes.

I was getting REASONABLE consistent metering with my RCBS Dandy little powder measure.

I used it for some practice rounds loaded with 8.0 gr of 800X.

To be safe though when doing the top-end loads I measure every throw individually...not like you are going to shoot MAX loads all day long...

One day I am going to invest in an electronic powder dispenser...

Anyone have 800x Data for 165 GDHP's? The new speer manual does not have 800x data, I may switch to AA#9 for this round and use my 800x for my 200gr XTP's.

Whew! Finally!!

Today I finally got to shoot some of my first ever reloads for the 10mm Auto. I have a G29 with 4.2" Storm Lake barrel.

I was able to shoot up to 10gr's of 800-X with no bad signs/symtpoms at all! (I shot 10 rounds and all the brass looked like the brass from my 7gr loadings, except more dented from the harder ejection).

Truth be told, I am amazed at how much of a ***** cat the G29 is... I was expecting the recoil to be much more than it turned out to be. It was almost pleasurable to shoot. Maybe it's the 21# Wolff spring helping that :D

Anyway, I'd like some ideas on velocity from at 4.2" barrel and the loads below or similar:

Winchester Brass - CCI LP Magnum Primers - 200gr Hornady XTP bullets - IMR 800-X - 1.26" OAL:

200gr & 9.3gr
200gr & 9.6gr
200gr & 9.8gr
200gr & 10 gr

(I shot all these loadings and more today... no problems at all.)

Note: Brass was brand new

Thought I would add that I also did some penetration tests with the 10.0g 800X rounds and the LWD bbl. OMG! 13 soaking wet phone books cascaded together for a total thickness of about 30". The 10.0g 800x load with 200g Hornady FMJ bullet almost penetrated through the entire bundle! It had about a quarter inch to go and it wouldve passed completely through! You can see wire bundle marks on the leftmost bullet. It hit the bundling wire somewhere near the middle of the stack. I also fired a .45acp Black Talon into the bundle. It penetrated a good 10-12" IIRC.

After these tests, I would have absolutely no reservations about using this 10mm round for all around woods protection in the lower 48.

I plan to do penetration tests with a 200g XTP next time. Same load, 10g 800x

Went out tonight and did a muzzle flash pic on the above 175gr Silvertip, 10.1grs 800X from a 6" barrel. I was surprised by the low flash compared to a 7.4gr Power Pistol 230gr GS in .45acp.

10mm Reloading Forum

Hard to see at this resolution, but several flakes were streakers.

f2.8, ISO 400, 4sec timer.

I have a question for the seasoned 10mm folks here. I just started working up a load for woods hunting/protection in my G20 with stock barrel. I started with the following load, which I found in this thread:

Starline Brass (once-fired, not new)
CCI 350 Primer
1.26" OAL
9.0gr IMR 800-X
Beartooth 200gr WFNGC

I worked up in .2gr increments from there. I started to see a hint of the infamous glock smile at 9.4gr. At that point, I was seeing about 1240fps, and I had fired about a dozen rounds through an initially clean barrel.

Here's my question - Does 9.4gr seem like a reasonable point at which I would start seeing the smile? I was expecting to get at least a couple tenths higher before seeing signs of pressure.

The barrel did show visible leading, but I never shoot lead bullets, so it's hard for me to judge if leading was an issue. Would leading from a dozen shots cause pressure problems? Should I try virgin brass to rule out the brass? It is range brass, not fired by me previously, although I did inspect it prior to loading.

All I'm trying to do is come up with the hottest load I can use in the stock barrel. If 9.4gr seems reasonable, so be it. If I can eek out a little more energy, all the better. Going to an aftermarket barrel is not something I want to do because I want a super-reliable firearm that will always go bang.

Thanks in advance for your feedback!

Mike,

9.6 gr of 800x behind a 180 gr XTP are plenty hot. The Hornady manual calls for 8.5 grains max. You say you used 10.8 ?

155gr Rem JHP, new Starline brass, CCI LP primers (not mag)
12.3grs 800X @ 1.260"
Glock 20 w/22 lb recoil spring and SS guide rod

AVG= 1,548 fps / 825 ft-lbs energy.
Low 1528 fps, High 1571 fps.

I feel with a mag primer, my 5" kimber should be getting close to the 1600 fps mark.

SDGlock23, I think you meant 1.26"...1.125" is like 40S&W C.O.A.L.

You mentioned that this was from the GLOCK 20 WAS THAT WITH STOCK LENGTH BARREL? (SORRY ABOUT THE CAPS)

Shadow, thanks for catching my typo, I changed it.

But yeah, it was from my Glock 20 with the stock barrel in it. I tad bit of Glock-belly, but nothing major.

You're welcome! I want to add IMR800X and AA#9 to my powder stock pile fairly soon.

I have mostly used Blue Dot over the years and more recently some Power Pistol loads to gain some velocities from the short Glock 29 barrel. Blue Dot has worked well from my S&W 1006 and other 10xx series pistols.

Most recently I purchased a Bar-Sto Match grade 9X25 Dillon conversion barrel for my S&W1006, got it fitted to the pistol myself but set the barrel off to have the chanber finished reamed to proper depth. My first outing with it was great, no failures to feed or eject with Double Tap 90/115/125 grain Gold Dots. I am gathering info to start loading for it, can't weight!

This Hurricane Gustuv has set me back some as I started cleanup today and shuffling generators around to various family members homes to save the refrigerators and freezers plus helping a few close neighbors. The good lord has spared my home once again, thank you...AMEN! I've been running on my generator for 37 hours already as we type here. Well I must get some rest sun will shine in the morning and famile is coming back, lots to do.

This isn't 10mm, it's the 10's little brother, the .40. But it is 800x using 135gr Noslers. Once fired Speer brass, 1.125", Win SP Mag primers and 11.5grs 800x.

6" barrel Glock 35
3 shot Avg = 1,705 fps for an average of 871 ft-lbs of energy.

Thought I'd share since that's quite impressive, to me at least.

Ran some 800x yesterday through the good ole trusty Glock 20. It was about 65 degrees, and I'm somewhere around 900-1000ft above sea level.

200gr XTP
9grs 800x, 1.270"
CCI 350 (LPM)
1x mixed brass

1182
1206
1165
1174

1,182 fps avg / 620 ft-lbs

The reason for being 1.270" is that using my old caliper, it said they were 1.260, but my new caliper said they were 1.270". They functioned fine nonetheless. Brass looked fine, a little dirty, but otherwise okay.

I've got 8 pounds of 700-x kicking around. Anybody ever use this for 10MM? I haven't been able to find any loads for it.

I've used 700X quite a bit in 45ACP target loads, but not in the 10mm at all. I know that it is too fast to develop the magnum-level loads that most of our posts about 800X talk about here, but there's no reason 700X would not be a decent target powder for the 10mm. I've switched to Green Dot for my fast shotgun powder, so I can't test any loads to get you started. I'd bet around 5.0grs with a mid-weight bullet would be a safe starting point. Like I said, don't expect it to reach magnum velocities.

175 gr Silvertip

Mr. Mcnett,

I am using your 180gr data with 175gr Silvertips to get at or just over 1300fps out of a 5" bbl using 800-X. Based on your writings I should start at 9.5g and proceed from there. I am using Doubletap brass (4 gr heavier over Win brand) and StarCrimp to hold a cannelure bullet. Should I use a CCI 350 cap or back down to a standard CCI LPP?

Thanks in advance...
