Do they make dies that will take once fired brass back to non fired size? 300 rum rcbs FL sizing die will put fired brass to SAAMI spec, .525 @ shoulder, .550 @ base. Non fired brass is .520 @ shoulder and .545 @ base. Haven't checked headspacing length yet. I have a lot of once and twice fired brass and can't size it to fit into my new match barrel. The camber is a lot tighter but non fired brass fits just fine of course.
