[QUOTE="Guest, post: 116896"] [ QUOTE ] [b] Brass life (reloads per case) depends on three things: how much the case is sized down form its fired dimensions, how hot the load is and the quality of the cartridge brass.[/b] [/ QUOTE ] Everyone seems to have missed a major determinate - cartridge. A 300 RUM at max SAMMI pressure doesn't have nearly the life of Bart's hottest 308 WCF loads. 300 RUMs typically get 3-4 reloading. [ QUOTE ] [b] I and many others get between 50 and 100 reloads per good commercial rimless bottleneck cases when fired in SAAMI minimum chambers and full-length sized such that body diameter's not reduced more than .003-in. and the shoulder's set back no more than .003-in. using maximum loads producing best accuracy.
