[QUOTE="codyadams, post: 2645062, member: 87243"] Seems pretty obvious, the loads are way over pressure..... 0.7 grains is not near enough of a drop for a component change of brass and bullets. In a case that size I generally drop 3ish grains or more from max I established with similar weight bullets any time I do a major component change like brass, and do a gross work up in .3-.5 grain jumps just to establish my pressure/velocity range and where I find max pressure. In that scenario, worst case is you shoot 10 or so extra bullets. Changing brass manufacturers, and changing bullets, and then dropping only .7 grains is asking for trouble. Then to shoot and blow 3 primers....you may have etched your bolt face, or possibly even set lugs back slightly depending on how over pressure you were. Please be safe man! That was minimum 75,000+ psi inches from your face, 3 times. [/QUOTE]
