Sounding good TB, what is the list of your other barrel chamberings you use?

Turkey with screw chokes, .410 full choke, and .58 cal huntsman (being modified to be 20 ga. smoothbore with screw chokes for muzzle loading shotgun. And my .50 cal Traditions barrel latches up tight, but I haven't modified up a forend to lock this in place yet.
