This may help, but only if someone knows what kinds of primers are used by these manufacturers. I recently replaced a firing pin in my 20-ga. Superposed. On the skeet range, it immediately and consistently began hanging up on Estate shells. I switched to AAs and it would then hang up only about once a box. I still have a problem, though, as I want to be able to shoot whatever kind of ammo is on hand.
Terry, can you explain a bit more about your procedure? I'm fairly handy, but no gunsmith. The pins will remain stationary enough that you can lightly knock off a squared edge, all without disassembly? What kind of tool is used for "stoning"? I've always pictured something like an oilstone for sharpening knives, but you're obviously talking about a precision operation requiring something small and handy. Thanks. TT
