[QUOTE="Rardoin, post: 2175841, member: 114954"] Brass neck life, without annealing, will largely depend on the amount of work hardening done during the sizing process. If you are using SAAMI spec dies that shrink the neck down a large amount, say 0.012"+ over fired size, and pull it back out 0.006" or so it will work harden the necks earlier and increase the chance of splitting. Periodic annealing can restore the malleability and increase neck life. As Mikecr pointed out, primer pocket loosening will get you first in any cartridge run on the upper end of pressure. I have some 6.5 x55 BJAI brass, that I annealed multiple times throughout their life, that have near 30 firings. I also have some of the same that were only sized in a Warner die insert that bought the neck directly (no expander ball or mandrel needed) to the final diameter down from the fired diameter (0.005" change) and were never annealed and have 20+ firings and no split necks short of one that separated at the N/S junction from too deep of a cut from neck turning.
