I have a straight 13/16 .36 caliber barrel, and I was wondering if anyone has ever swamped a straight barrel? I know it will probably be hard but has any one done it. When I bought it I was not wise to the greatness of a swamped barrel. I don’t really want to go through the “trouble” of selling it and then buying a swamped barrel. I would rather go through the “trouble” of sending it to someone who would machine it and pay them. Or swamp it by hand. I know that sounds silly but I always loose money when I sell stuff. Any pointers in how to do it. Thanks!!!
