[QUOTE="Mikecr, post: 868844, member: 1521"] Prepped case mouths, as in fully fireformed, can vary +/-5thou(and clear of chamber end) without detriment. Shoulder distance bumped from fireformed needs to be tight at 1-2thou. Length of loaded rounds (COAL) is pretty much meaningless unless you're limited by a magazine. W/regard to accuracy, you need to hold cartridge base to ogive(CBTO) within a few thou. [/QUOTE]
