[QUOTE="J E Custom, post: 1222358, member: 2736"] The reason that the stamped end is normally the chamber end is because in the final testing stage of a barrel it is not unusual for the bore to be slightly tighter on one end (Normally only a couple of hundredths of a thousandth (.00001) and you want the tighter end at the muzzle. The other reason is the lapping process. some barrel makers make a saw cut in the muzzle end to identify the muzzle. So the barrel maker notes which end buy stamping the bigger end or saw cutting the smaller/tighter end. In theory, the tightest end of the barrel helps makes up for bullet lose while engraving.
