[QUOTE="MagnumManiac, post: 2239715, member: 10755"] No….it will have more pressure than virgin brass because some of the pressure is used in virgin brass to fire form it. OP, it is a well known fact that ADG brass hits pressure early, it is substantially thicker (LESS VOLUME) than other brands. Stiff bolt lift is a sure sign you have surpassed safe pressures for THAT BRASS. It matters not that you haven’t reached the book max, or the velocity you’re expecting. Brass expands in ALL directions, it has a plastic tendency, which is why brass is used, it expands then shrinks, BUT if you expand it so much that the action also springs, the brass has lost it’s spring and doesn’t shrink back, this is what causes stiff bolt lift. This is bad for your bolts lugs and the actions abutments, over time with continuous hard loads, the 2 can gall and even setback over time. ANY hard bolt lift is a sign to back off, whether other signs are present or not. Cheers. [/QUOTE]
