[QUOTE="AZShooter, post: 1754850, member: 5219"] Can bet the reason for the square crown, no need to get bore precisely centered in lathe. Even if not true a tool bit passing across end of barrel will make a perfect 90 degree crown. Square edge should not be an issue. If a plastic coated cleaning rod is used I see no reason for worrying about rod bumping into the edge. Now pulling a bore brush rearward would be another story. [/QUOTE]
