I worked on one a few years ago. The customer fired it with some Corbon ammo and with the larger shotgun firing pin holes in the breach face the primer pierced and the escaping pressure blew the stock off it. He brought it to me to bush down the firing pin holes and turn down the pins. When I was done with it it was much safer and didn't even crater the primers.
Something to consider.
i was actually considering doing that same thing. can these actions take higher pressure loads like the corbon?
