Hey all,
Somewhat of a shot in the dark question but is there a number/ measurment used by gunsmiths when working on a side by side shotgun as to how far past the face of the standing breach the firing pins should protrude to hit the primer of the shell? I am working on a old West German side by side 12 gauge shotgun. Not sure the actual manufacturer but i've been told by a few guys that looked at it that it's marking are from that part of the country. Very well made boxlock although it's been handled roughly by amateur gunsmiths in the past.
I suspect from dry firing so many times the shape of the firing pins have changed/ elongated ever so slightly from the force of inertia through the holes in the standing breach. After firing the gun it's hard to break back open, the firing pins dig down through the spent primers. You can see the marks clearly on the primers of the spent shells. I'm thinking this is the cause of the issue, or I hope so anyways...
Thanks in advance!
