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.

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.

Shadow, you can't go wrong with 800x, that's for sure. Oh, and good luck with Gustav!

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...

BrenTenVltor We haven't seen Mr. McNett here in quite sometime(busy man these days) but you don't have too use the magnum primer with the IMR800X powder, although some people do.

My data for the 180 gr bullet with IMR 800X is 8.7 @ 1210 fps at 30,000 CUP, please do NOT confuse the CUP vs. PSI data.

You should start at lower load weights and work up the load in 0.02 grain incraments because not all bullets, barrels or pistols are alike. And the cases too as you have mentioned. The star crimp you mentioned maybe too much, most just use a taper crimp to secure the bullet to prevent setback issues.

Best regards good luck and be safe!

800X and 135 JHP

I just ordered 2k Nosler 135 gr JHP and a few pounds of 800X. Also have a new 20SF, what is a good starting load and OAL for my mountain of mixed lot of range brass? I have a lot of experince. Also looking for primer choice, I have 1k Federal LP, but it looks like people are running magnum. I don't want to go crazy, seeing as I am using range brass, but would like to end up somewhere around 1550 or so and get a few loads at that level before turning it into target brass. Is this possible? Thanks in advance.

This is what Mike McNett posted in the second post of this forum:

I would strongly suggest you follow his warnings while working up your loads! Your powder is of a different lot #, your primers will be of different lot#, etc.

Take your time and work slowly otherwise that "CRICKET WILL GET AWFUL NOISY"!

Thank you Shadow. My 10mm IMR manual has a load for 9.7 of 800-x for 1330fps. This is just what I am looking for, a 1300fps load out of a 5 inch barrel for the new Fortis (Bren Ten). The Silvertip is my favorite bullet and this should work great.

I everyone pretty much running magnum primers with 800X and 135 NOS? What are the numbers for range brass? Honestly, big numbers are not worth the cost of new bras (to me) but I would like to see what I can do.
