Easy there, I don't think Butch meant any offense just as you did not. We both gave the OP our take on it based on many years of experience as professional gunsmiths. I happen to think reaming an improved chamber by hand is not a great way of doing things for various reason but this doesn't mean it can't be done. I know at least one guy who is so exceptionally skilled at doing things by hand that he could probably get a good result most of the time. It is my opinion that most people will not. As for myself, I'm better off using the lathe, for sure. GD
