The military is using bimetal cases and 80+kpsi So other than beating the crap out of the brass is there really that much to worry about if the load conforms with regular signs? No excessive primer flattening. No sticky bolt lift. And lastly primer pockets that last a reasonable amount of firings.
If the brass lasts 7 or 8 firings and the bolt ain’t sticky. It’s all good you guys worry too much.
