I bought all the parts for a SBH off of Gunbroker to get the GF. All the parts are there including the cylinder. If I fit the cylinder to one of my 45's, is there a smith who will just rechamber the cylinder to 45? Or is there a reamer made to do this that I can purchase? I guess it would have to have 2 pilots, one to guide on the 44 cylinder, and one to guide on the 44 throats. I also bought an OM Super. Is there anyone recommended to simply rechamber/rebarrel to 45 without getting into the $2K custom realm?
