Hi:   New to 10 mm but not to reloading. I started with once fired brass & worked up to 9.5 gr of Longshot & 180 gr Xtreme plated HP & GD HP's   According to what I have read here 9.5 seems to be a nice moderate load. I have noticed no signs of excess pressure on the brass.
My question is how many times can the brass SAFELY be reloaded before being retired?
Thankd
BTW they are being shot in a Para 16-40 (Canadian) Limited that had the barrel reamed by Fusion & installed a 22Lb recoil spring & 25Lb main spring

The brass sometimes gets lost before it goes bad, but understand that it can and does work harden which can lead to loose bullet to case tension (setbacks) and cracks and splits.  Also brass can get beat up on the extractor rims as well.

I use a pass-through system to help eliminate any expansion down very low on the case near where the extractor groove cut starts.  That area is not reached by the dies because of the shell plate or holder and the radius inside the sizer dies.

All that said on lighter target loadings I have seen 10+ times with some heavy loads less.  Just understand your firearm is a machine and anything can and will cause issues with fitment.

Hey Erikk!  Welcome to the forum.

We have twins!



Canadian Para that I had reamed to 10mm.  Mine was done by Mars Guns, and I have loved it.  I run a 25lb main spring, a flat bottom firing pin stop and a 18.5 lb recoil spring.

Like Shadow, I push through size my brass for full length.  With moderate loads I shoot them until they are lost, the case mouths split, or they won't hold bullet tension any longer.  I don't think I have very much brass that has made it to 10 reloads using that criteria.  All my brass is starline.

My para is a pretty tight barrel, though before I got it the barrel had been throated a little agressively.  It will smile brass worse than my Glock's in heavy loads.  But in the mid-range loads, I get minimal case head expansion, and the brass seems to last a good long time.

Welcome to the forum.

I haven't shot a lot of 10mm yet......prob a total of 1000 rds.  My 5 gallon bucket is still pretty full, and it will be quite a while before I go through it 5, 6, or 7 times.  Tracy

I'm the same way, easy 5+ times. Maybe 10+. I also load Longshot at 9.5+. Brass should go a long time. I wonder how long if I load 10. Just saying.

Thanks but not quite  :-) Mine are not stainless. These are almost twins   A 40 & a 10MM   Bought the 16-40 cause I got tired of lugging 8 45ACP mags for my WC to re qualify for my HR 218 every year. Then I starting to read about the 10MM & how easy it would be to have the 40 changed to a 10mm. Found the Limited on Gunbroker for a good price and had Fusion convert the barrel (they are just up[ the road and Bob is a great guy) 
Would like to try some Buffalo Bore or such (just to try a Nuke)  but just can't see paying $35.00 for 20 rounds. Maybe I'llc start to play a bit with the Longshot and see what the Chrony  tells me
BTW   GREAT SITE!!

Step one...

Go through your brass and remove any PPU head stamp and junk it.  Its not fit for reloading.

Second look for smiles if your pistol is capable of doing that (or if its pick-up range brass) and remove those from the mix.  Same with splits.

Last, If I can find it and none of the above applies, I reload it with moderate to moderately strong levels. 

If you are pushing the limits with the load, go with new Starline brass as it is quite economical in quantity.

Really? I haven't noticed PPU splitting any more than any other manufacturer's brass.

Not that I have a lot of PPU, but I'm not afraid of it.

I've never had a split case either, but I did loose a frame to one.  Nothing like having a case failure right in your right hand.

You may load it if you'd like, but I run the SUV over it before I toss it in the brass barrel at the range.

I had a 45ACP Americ range pick up let go in a WC KZ 45 & it was not fun
blew the mag out and got peppered with some brass fragments
. Lucky my glasses  are poly carbonate safety glasses
Would post a pic but for some reason even my smallest photos are too large to upload
Finally stopped raining so time to go out and chrono some more 10's

It feel like getting stung by a baseball bat.  My magazine hit my foot.  Powder residue lines were imprinted on my hand anywhere there was the slightest gap to find its way out. 

I was letting another man at the range fire the gun half an hour before, and as much as I don't want to have it happen again, I'm just happy it was me instead of someone else.

Greg

If you've been here awhile, you may have seen these...









Greg

Only problem there is I can show you other manufacturer's brass that looks almost that bad....if I had saved them.
