tks ...good info on crimp
You can read from the data that there isn't much crimp being applied, as the bullet did not have a crimp line or crush.
Bullet pull was about medium hold. The Littlestone ammo showed much less crimp... ???
yes... but it just fit the call on I thread I posted.
I was wondering as to the taper crimp...on my test runs of 10mm. I have no crush line, heads to .3995- .400, but still mid hold. I'm taking the numbers to comare to mine. As long as the set lenght is good and I can't push/pull easy, I'm assuming its ok, but had no data.
How do these shoot in glock 20?
would this or ppu be beta?
both are under 40c/rd on gunbot
To Filthy Phil, Both should be good blastin' rounds for proficiency drills or just target play...
To tommac919, More info on the bullet hold, those Armscor cases appear to be shorter @ 0.9860 instead of the 0.9880", that would yield less crimping and also the cases are sized down more @ 0.4200" and being stretched out by the bullet as seated @ 0.4225", therefore the bullet is firmly held despite not much crimp to mark the bullet. Remember the 10mm is straight walled case, unlike the 9mm which is tapered wall.
^^thanks
Are both brass worth saving?
I have reused both PPU and A USA brass without issue...there were some reports of others having had cracks and splits on the initial firings of the factory loads a while back. Not everyone retrieves there brass and inspects so how many is hard to tell.
Although I haven't seen any recent post of issues.
