[QUOTE="J E Custom, post: 1734838, member: 2736"] Both Belted or shouldered cases can/will have case head separation if not sized correctly or to much. The tighter the space between the case head and the bolt with the round seated against the shoulder the better. Case stretch is the culprit and anything that can reduce it will help prevent head separation. To be honest, I have never "Bumped" a shoulder when a partial full length sizing was all it took to chamber the round without altering the case length. Different brands of cases will last a different number of firings, but improper sizing or over sizing will reduce the number of firings of any brass case. Belted case are the most notorious for case head separation because if sized the way they were intended to be there is lots of clearance between the shoulder of the chamber and the shoulder of the case if head spaced on the belt. Improper sizing is normally the biggest cause of this problem. J E CUSTOM [/QUOTE]
