I am looking at am easy way to convert a single action into a .25-20.
Am I correct in thinking that the RB22AW (rimfire Bisley)is on a large frame? Would it be difficult to convert the firing pin from rim to center fire? I'm thinking just replacing the recoil shield and firing pin, but don't know for sure. Starting with a RB22AW It should be a simple matter to ream the chambers, convert the firing pin, and replace the barrel with a .257 bore. Or I could buy the Bisley, send it back to Ruger for a "replacement" cylinder, put the "replacement" cylinder in another Blackhawk in .357 or such, and have it reamed, timed, and re-barreled. I know Ruger would replace the cylinder in the Bisley cheap, but probably wouldn't sell the cylinder separately. Bowen wants about $235 bucks for a Blackhawk cylinder with pilot holes only. It is a high quality part, but pricey. Using the replacement cylinder would mean I would be stuck with a factory new Bisley in .22, I don't see that as a problem.
