[QUOTE="Arapaho, post: 2654948, member: 111801"] Measure the case web near the base of a new piece of brass and then measure the web on a piece that was hard to extract. BR2 primers are hard and it takes a lot to show pressure there. The problem may have came from hot loads during load development (especially the brass that had primers fall out) and weakened the case web. I have ruined nearly a whole box of Nosler brass in my 280 Ackley that extracted fine on the first firing but was hard to extract on the second firing. I found that in this caliber, once the case web over expands from hidden pressure, the brass is basically ruined. Once I got a load, I just used new brass and it reloads and chambers and extracts fine, after firing. The case web is about 1/4 inch from the rim of the case, where the brass begins to thin. I can send you photos of my ruined brass if you need them to show you where the case web expands too much with too much pressure. This caliber and my 7 SAUM seem to hide pressure and if you aren't careful, the case web will suffer. May not be your issue at all but worth checking. [/QUOTE]
