I would bet money you will blow a case head if you keep doing that, and sooner rather than later. When you do, it'll probably ruin the magazine, and maybe ruin the frame.
Back away I say.
Those are some seriously bulged cases my friend! If it were my gun I wouldn't be running anymore of those 255 gr. +PS through it.
You're probably seeing a combination of a max-spec Glock chamber and max-spec +P pressure. It'll probably be just fine in a correct 1911 chamber.
I tried a pic but it didn't work. I'll try again. Headstamp is A USA
Don't know what that is. Hopefully not A-MERC rebranded.
Just drop test the ammo in the barrel to see if you have the same lack of support..
stop talking sense
It might be Armscor. Not sure.
I run a maximum listed +P load with Accurate #5 and 200gr XTP through my G30 and they don't look anything like that. Very slight bulge with brass and almost none with nickeled.
According to Google, A USA is the Armscor headstamp since about 2009. If Doubletap gives you the brush off or tries to blame the error on you, I would contact Glock next. They may looking into the issue a little deeper.
it may be Double taps problem - BUT it's YOUR fingers.....
I have read what the other folks have said on previous posts.
I have had, modified, and built from stripped frames 1911's from .22 LR, 9mm Para, .38 Super, and .45 ACP over the years. Just my $.02 worth:
IMO, the 1911 .45 ACP as designed by JMB was for a subsonic hardball round firing a large projectile. If one wants to fire anything heavier, faster, or HP bullets, one needs to throat the barrel (Jerry Kuhnhausen). Therein is the rub. The throated barrel needs to support the bottom of the cartridge case so as not to cause the bad case bulges you show.
If one wishes to do .45 +P cartridges (to me an oxymoron), one must think about replacing parts to accommodate .45 Super or .460 Rowland (specialized barrel, et al). Just boosting powder charges with the .45 ACP is going to cause problems which your cases exemplify.
If one wants a high velocity hard hitting 1911 type pistol, one should really look at this:
I am too old to spend that kind of money, but 20 years ago I would have done it if not for all other projects I had then. I regret not doing it. To me, that is the ultimate 1911 type pistol. Very heavy for a 1911 type, all steel, long dust cover, and the 5" barrel model.
If someone wants to lay $1500 on me I would go for it and I would spend the extra change.
I would not shoot that ammo.
Has the barrel been modified to help feeding?
And, the barrel leading is another big risk with polygon rifling you should be familiar with.
