Just sayin, Gryffyd, nailed it, and it was so simple everybody just blew on by.

And, OLD FUFF, is correct, a pilot throat reamer,which is what I assumed we were talking about all along, is the only way to do this, you do not want to learn on your own gun, have a pro, do it.

That said, I don't think that you are going to get a lot of improvement in terms of hand-held accuracy

For me the biggest benefit I got from having my cylinders reamed was reduced leading.
