I am trying to help out a buddy of mine with his shotgun. He has a 1959 Browning Belgium A-5 in 12 gauge. He is wanting a Japanesse Browning A5 28inch barrel that can shoot steel shot. He also wants it to be able to be choked. The gun will shoot up to 3". Does anyone have any experience with this type of setup? Just trying to get some info to point him in the right direction.
