ive got some .45acp hardball rounds in 50 round boxes. I noticed recently when i looked at them that some of them had some quality control issues and the bullet seating depths are all staggered and they arent very consistent in about 3 out of 10 boxes i bought in the same lot number. I went through them last night plucking out the rounds i felt werent safe to shoot and put them in a plastic bag to deal with later and reboxed the acceptable rounds together. My question is just how much bullet setback is okay and how much is too much? I basically took a known good round and compared it to other iffy rounds but i really dont know just how much i could get away with to avoid blowing up the chamber in my gun.
