Sat down to prep some commercial 7.62x54R brass recently, and ran shells through the ol' RCBS FL size/decap die. Most went smoothly, 1 primer stuck to the walls of the pocket and the depriming pin tore the top out of the primer, leaving the walls stuck to the pocket sides! I've never had that happen before, checked with a buddy that has a swager, but he said it will only trim the lip of the pocket, not "bore out" the excess primer material.
Any favorite techniques on getting the primer remains out of the cup without damaging the brass? Reloadable in this caliber is hard to find, and I don't want to waste it!
