I don't anneal, so the case neck splits before the primer pockets gets loose, usually around 5-7 loadings. We shoot 2-gun every month, have about 2-3 squads and there is only myself and 1 other guy that reloads, so we get all the brass we could want.i do pretty much the same. and I have been annealing every reload, so i can only tell by primer pocket.
