Hottest 10mm load

[gandog56]

Retired Squid? I did only 6 years in the Navy. Left an E-6 because I didn't want to deal with all the government red tape and paperwork when I started to run the ship's calibration laboratory. That and the only shore duty they wanted to give me fo re-upping was Norfolk, VA. No thanks! I was a decommissioning ships crew there, and hated the place. Wasn't about to do four more years on the big grey boats. And about one month after I got out, my last ship was sent for an extended stay in friggin' Diego Garcia! Probably way worse than Norfolk!

Well, when I see you also going after me over something I posted in another thread, what else am I supposed to believe?

I did not go after you.  They are two different threads on entirely different subjects in entirely different subforums.  Nothing in common but you and me which is only coincidence.  I have nothing against you personally.  I also don't see this as a thread to bring up TM/GZ and therefore will not comment about it here.

Is there any chance you will answer my questions asked below?  If not that's fine, but they were an honest part of general conversation within the context of this thread.  I'm starting to feel like you're more worried about what amounts to nothing than honest conversation in the first place.  My thing at this point is I can't figure why you commented at all on some of what you did below if you never cared about honest conversation in the first place.

I would like to get along.  I have no real animosity toward you and never did.  Let's let misconceptions be bygones.

P & E Planner for ET & MIRC's labs on USS Shenandoah AD 44, off and on in the '80's and enjoyed writing controlled work packages for level A and nuke repairs. Planning for ET's & IM's cal shops was just boring, EM shops were a PIA because of all the different sizes and mfg's of motors, but I really liked doing R-5 weapons and weight testing.

Weird, I was a P&E planner and ET on the USS Howard W. Gilmore (AS-16) about 1980 before a slot in the calibration lab opened up.

Small world.

The things I also take into consideration are:
The Gun - its trigger pull and reset, sights (target or combat style), balance and weight and barrel length.
The Ammo - what is the intended use (personal protection, hunting, target or general plinking), which ever it is it has to run 100% functional.
The Shooter - Needs to understand his limitations, strength or weaknesses, the guns limitations as it pertains those the needs.

The Bullet - selection, design (JHP, FMJ, Cast, SWC, other), weight vs. use.  We 10mm users are using the current bullet designs as produced by the manufactures which are mostly designed for the weaker 40S&W cartridge performance envelope.  Therefore when we push the envelope of the design characteristics, we may see some negative results in terminal ballistics.
The Hornady XTP's are a tougher bullet, but I feel the 200gr XTP HP cavity is a little too small, but will work

I would love to see Hornady release their Critical Duty bullets for reloading. It seems to perform the same, with identical expansion characteristics & weight retention at a huge variation of velocity. It could be a great bullet for pushing at high velocity in the 10 even though it performs well at under 1000fps in the 40. I use the +P load in my 9's as my carry load.

Well, when I make a post and you deride it after posting nothing there from before before June 3rd, what am I supposed to think?

That brings up a good point, we see the people in the 9mm and 45ACP and other cartridges adding "Plus P" & even "Plus P Plus" loadings yet the manufacturers' keep down loading the 10mm!  Go Figure!

We would love to see it loaded at its original loaded velocities and within the SAAMI MAP.  The powder companies should also post realistic loading data at the upper SAAMI MAP for more realistic performance pressure values... :'(

Well, since the only store bought 10mm I own is two boxes of Underwood TMJ and two boxes of Ted Nugent JHP, that's OK. I can reload them to whatever level I like.

my reloading manuals are showing 2-300 fps slower than underwood velocity. what are they doing? i assume it's powder, but not sure and if it is, what kind of powder and where does a guy get it? thanks

Underwood used to exclusively use IMR 800x in it's 10mm loadings, but now we are seeing some loads with Power Pistol and others.  If you go to the 10mm factory pull down subforum you can read all about the loads... but you will notice that Underwood's loads are way above any published book load, so work up to them and use extreme caution as there is very little margin of error at that level.

Also, Underwood level loads should not be fired in a factory Delta Elite or other pistols with poor case support.

[semper68fi]

thank you..

[Retired Squid]

Sounds like they loaded for Kimber type chamber (full supported and way thicker chamber then my Colt) and with 23# to 26# recoil spring.

YES to both statements!

Point taken.  But it's also reasonable to point out that where pressure levels aren't published for a max load, it doesn't mean the max listed load is at or anywhere near SAAMI maximum average pressure.  Many max book loads don't even reach pressure levels of Winchester SilverTip factory 10mm ammo, which itself doesn't reach SAAMI maximum average pressure.

So yeah, if one is going to attempt loading beyond whatever max book recipe, it must be done methodically and carefully.  But it doesn't mean there aren't great SAFE gains to be found beyond plenty of max book recipes.
