I'm fairly new to the 9mm. I've had one for a number of years but haven't loaded much for it.
A while back I got a deal on 1000 once fired 9mm cases. Most of them are military and still have the original primers. I haven't used them but got them out this morning to load up a few. I miked a few and found them to be between .735 and .745. The specs call for a trim to .751. Just how short can they be anyway? What happens if I shoot a .735?
