[QUOTE="bigedp51, post: 1506256, member: 28965"] Below is a exaggerated illustration of the effects of excessive pressure on the base of the case and the brass stretching beyond its elastic limits. The brass case is a expendable item and not worth having a scored bolt face from a leaking primer pocket. [IMG]https://i.imgur.com/IBJQA9p.gif[/IMG] Below on the left is a Federal .223 case with a thin flash hole web, and on the right is a military Lake City case with a much thicker flash hole web. The thickness of the flash hole web adds strength to the base of the case and and the longevity of the primer pocket. [img]https://i.imgur.com/cYeTsDp.jpg[/img] Below is a photo from a AR15 reloading forum and the person who posted the photo said he didn't worry about loose primer pockets. And he also stated he would just replace the bolt when it got bad enough. [img]https://i.imgur.com/VMkEdYr.jpg[/img] I use a simple test for loose primer pockets, below is a Lee depriming tool and if the primer moves with just finger pressure the case goes in the scrap brass bucket. [img]https://i.imgur.com/m1PlERq.jpg[/img] The cartridge case is a expandable item and the last thing anyone needs is a scored bolt face trying to save a few cents. [/QUOTE]
