I swapped into a nice Freedom Arms 4 3/4 inch at he last gunshow and I was wondering if it would be advisiable to shoot 45LC in the 454 casul. Freedom Arms advises against it because of the powder ring it builds up on the end of the cylinder. A lot of people shoot the 45LC in the 454 casul . I think that as long as you clean it properly after shooting it you would be okay. Anyone had any problems with this happening. I called Freedom arms wanting to see if I could swap the cylinder and maybe pay some boot for a 45LC cylinder but they don't do that but they will gladly sell you a new cylinder for 418 dollars and you have to pay shipping and insurance both ways so it is quite expensive.
