I've got a wonderful old Griefelt 12 gauge with VERY thick Krupp steel barrels both choked .060, Nitro proofed 2 3/4" chambers, and I'm wondering what the heck to do with it, since I don't shoot waterfowl. I don't recall seeing barrels this thick on a shotgun. It's a finely tiny scroll engraved sidelock hammer gun with outstanding wood, a high condition gun. I really don't want to modify the chokes, since someone else might want it just as it is. Anybody out there looking for something like this?
