I know most guys on here are not gunsmiths as I am not either, but this is the only group I can ask these questions. Up here in northern Wyoming,(where it's -12 degrees F today!), most people have never even heard of a double rifle. If they have, they were telling their buddies that "DANG! I seen a gun that costed $20,000! That's five times what I paid for my pickup!" All jokes aside though, I even talked to the gunsmith I use to work on my m-14 about it. He has never even heard of anyone ATTEMPTING to convert a shotgun, but he's willing to take a stab at it. I have confidence in him as he was a tool and die maker for a lot of years and is now semi-retired doing gunsmithing. So almost any advice I get on here helps me with my twisted thought processes on this project. Thanks!
