I've been using Cowboy .45s for shooting tin cans at 20 feet with an earth backstop as suggested by the local gun-shop. They're a bit expensive, but fairly consistent as far as I can tell. I keep my Judge loaded with the PDX1 round in the bedroom otherwise (no kids or crazy people in the house). I've seen arguments both ways about the PDX1 vs Federal 000 buckshot. Before I go out and buy more ammo, I'd be very interested in some current informed comments about the best ammo for casual target use and serious self-defense with the Judge. Thanks!
