I'm thinking about a 460S&W barrel for my encore (Katahdin barrel). I understand I could shoot 45Colt and 454 ammo through the same barrel. What level of accuracy can I hope to get with these calibers. I don't reload so I'm talking in terms of factory loads. I like the idea of being able to shoot three calibers from one barrel.Is this a waste of time or is there any value to this?
