I have a question. How is it possible to cut a chamber with a reamer and get a bulge deeper in the chamber or in this case near the shoulder? I can understand getting a bulge at the rear near base but not forward. With some kind of a boring bar I can understand but not with a reamer. I only ask this because I am confused as to how this can happen.
Thanks Chet
Lateral force on the reamer tail.
The far end 'wallows' the chamber.
Hand reamed chamber?
I have seen more than one that was oval.
