I too have a Trapper 12 ga. Unfortunately mine has the unlined barrel and the infernal screw in choke system. Have thought about having the barrel shortened to get rid of the screw in. Have refinished the stock as I did not like the "painted" om walnut looking finish. It is a good shooter that I have used succesfully on Turkey squirrel and rabbit. Also generates a lot of looks at the trap range :: In addition I have a .50 cal. CVA Mt. Pistol that is a great shooter and fairly accurate.
