I have heard of pistolsmiths changing the angle of a revolvers forcing cone (I think thats what you call the end of the barrel where boolit enters) for improved accuracy. I was wondering if anyone has tried this and was looking at Brownells but could not find a tool for a do it yourselfer. They do have cylinder chamber reamers and muzzle crown cutters. Maybe I did not look hard enough.
Anyway does anyone think this a benefit? Is a certain angle better than another. I shoot some pretty old revolvers and was thinking they might benefit from at least a "cleaning up" in this area. What ya think???
