I've never owned a Judge but I did have a TC Contender with a 10" barrel chambered for .45 Colt/410. When shooting 410 through it it had a screw in choke that was groved to straighten out the shot that would have otherwise came out like a spiral galaxy due to its rifling. I would shoot clays with it, drawing from its huge holster after the clay was in the air. Very cool.
