I recently bough an unfired Winchester M23, 12 gauge with 28 inch barrels and got a good buy on it. I had planned on putting in choke tubes but the OD of the barrels is only .797 and Mike Orlen say there isn't enough there for him to do it so my only choice is Briley at a cost of $400 plus shipping each way.Briley isn't even positive they can do it but think they probably can. My hunting days are over and I had planned to use this gun mostly for skeet maybe an occasional round of wobble trap. The chokes on it measure .015 on the right and .035 on the left. That full choke on the right is a bit tight for skeet. It's a 12 gauge gun and I have some 20 gauge Chambermates to use with it as well. I can have the chokes opened up by a local gunsmith I trust and indeally I'd probably go about .005 and .010. Will this kill resale value? I don't plan on parting with it any time soon but hate to substantially hurt the value.
