Not sure if i have came across any or not. I had some brass not cooperate though. It goes in the scrap bucket. Crimped 9mm i do not keep. I have so much 9mm not worth the time reaming the crimp out.
Normally I would have just assumed the same, but the rest of the brass shot through the same guns was fine...only the Aquila was swelled up like rotten sausage, not simply Glocked which I am quite familiar with. All the rest of that brass sized just fine. I have tossed more than a few pieces of Glocked brass and also ran a few into the sizing die in the past, but never got these results. Anyway, just posted as info to do as you please with.That's the infamous "glock smile". They say you can salvage them by using a lee bulge buster die but i just trash them when i see them. I used to find quite a bit in 9mm and 45acp at my range but either the guy isn't a member anymore or he bought new guns. either way it doesn't hurt my feelings.
Lots of brass from two guns; two .40 caliber guns. All the other brass with Win and FC headstamps (I think some Remington also) was just fine, only the Aquila looked bloated. I only posted so folks might be aware. I suspect some bad stuff from Aquila, that is all. I have loaded a few rounds myself over the years...seen some things...just sharing.It takes about 65,000 psi to flow brass so I'd say that Q.C. let some hot loaded ammo out of the plant. I load at least 20,000 rounds a year to shoot through my 9, 40 and 45 and have not had any problems with Aquila brass. Some of the 9's that were shot with major loads in Open guns have looked like that though. Scrap bucket for sure. The only other explanation would be that the 40's were shot through a 45 but then the front of the case would be expanded to 45. Shooting 9's in a 40 or 40's in a 45 happens more often than you think.
