You might want to contact Chuck Boswell at Kicks Ind. They manufacture chokes for all your needs. Been using their chokes for at least 10 years. Have had them thread several shotguns. They also do forcing cones. They have several styles such as High Flyer for steel, BUCK kICKER FOR BUCKSHOT, a sporting clays series, turkey tubes, as well as card shooter tubes.
