[QUOTE="Bart B, post: 381739, member: 5302"] In my opinion, more often that not, short brass life is caused by sizing the fired case too much in body and neck diameters as well as setting the shoulder back too far. Loading to pressures higher than SAAMI or factory specs is another cause. Primer pockets should remain tight for at least 10 to 15 reloads. Belted cases can be reloaded 15 to 20 times in full length bushing-type sizing dies that reduce body and neck diameters as well as setting the shoulder back 2 to 3 thousandths. Us a bushing that's 2 to 3 thousandths smaller than loaded round neck diameter. And you'll need a special die to reduce the body diameter at the front edge of the belt that conventional full length dies don't size; get one from [url=http://www.larrywillis.com]Innovative Technologies - Reloading Equipment[/url]. For rimless bottleneck cases, one can get several dozen loads per case doing the same thing. And best accuracy usually happens when fired cases are so sized. [/QUOTE]
