In any case, I haven't heard anyone say that the 7.62x25 FMJ should be used for self defense. I think we're all in agreement that the best use if FMJ is on the target range.
Has anyone here ever done a wildcat cartridge? Anybody have any idea what it would cost to make a custom barrel for a Glock 20? And dies? Giving more thought to the idea of a 10mm or 40 necked down to a 30 or 32 cal...
