My uncle died years ago and left me his model 37. Great shotgun but he put a bulge in the barrel right behind the mounting lug. I have another model 37 that I use for fowl and this one has been cut off and relegated to safe dust. I don't really know what to do with it. It now wears a 18.5 barrel and has that damn bulge in it. It's safe to shoot shot but I'm not interested in slugs through it. There it sits. I have a small collection of guns that I need to get rid of and can't because of flaws that devalue them pre to bad. Even the LGS wants nothing to do with it. Any ideas what to do with it that doesn't involve spending twice the value on a new barrel?
