Well, I have an old Crescent Peerless model 12ga, and it is a great old gun, but it has or is becoming loose at the action or the correct term may be 'off face". What needs to be done to fix it? It is a good old gun and has good barrels on it, and I (in the past) never thought twice about shooting high brass 2 3/4 loads out of it for turkey hunting, I don't shoot anything out of it now but I really hate to see it become a "wall hanger". Thanks for any info you can provide.
