[QUOTE="BountyHunter, post: 289973, member: 12"] Case head separation is a sign of improperly adjusted FL size dies and can happen in as little as 3-4 firings. IF your dies are adjusted correctly to give .002 bump on the shoulders, case head separation will not be an issue. As for the usefull life, you will see other signs depending on the pressure you are running and overall softness of the brass. Primer pockets will loosen and necks will work harden are the two most common. Necks can be reannealled to lengthen life and less pressure will keep primer pockets intact. I have run cases as many as 30x and Tom Sarver who set the IBS LG world record group at 1k with a 1.4xx inch group, 5x and 50 score had 54 reloadings on his cases at the time of the record and retired them at 80 reloadings (Lapua brass) and annealed after every shot.
