There were straight walled 45 acp steel cases and 30 carbine in one of the big wars.

One of my buddies bought who knows how much surplus in 45... now and then a few won't go bang, but never issues with jamming.

YMMV.

We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
