[QUOTE="backwoods83, post: 851360, member: 29890"] Just because a primer pocket gets loose, that doesn't have **** to do with abuse of cases or any rifle per say. Not all brass is made equal, actually everyone favorite (lapua) has less tin and chromium than lesser brands and is usually 77% copper and 23% zinc, went cartridge brass should ideally be 75% copper 24% zinc .5% chromium and .5% tin, like winchester for instance, it isn't very uniform but its as tough as nails. Also the locking lugs will let you know when its time to step up to a bigger case, when they start gualding up, then you're damaging the rifle, other than that if a manufacterer chambers a 65k psi cartridge, you can bet your *** the rifle was proof tested to double that pressure. This also means that all europeans are idiots as well, since they run some of the same cartridges we have 15-20% higher in pressure than we do. 338lm for example, they run it just shy of 70k psi we cut it back under 65k. Primers are the most useless way to check for high pressure than any other method. [/QUOTE]
