I know champfering is a common(?) modification on BP revolver cylinders. I now own four revolvers, all .44, and plan to buy at least one .31 and .36 caliber revolver. I want to make my guns the best they can be, but I'm not sure about champfering cylinders. I've been shooting my 1860 Colt Army (reproduction) for 50 years abd have always watched for the ring of lead to be shaved off of the ball when loading. It makes me think I'm getting the exact right fit of ball to cylinder. Seems like the ring won't be shaved off in a champfered cylinder. Why do I want to champfer my cylinders?
