I think the primer pocket will wear out eventually using those orings..........
Over the years i certainly have seen primer pockets get flame cut, and ruined. This plug never gets any flame around the nose of the primer, ever. What is it you believe will cause the wear of the pocket? Nothing is working on it? Maybe 1200 shots, maybe more, so far, judging by the big primer box, and more, emptied.
Of course, nothing lasts forever. ☺
