Thanks for any insight you can give me.
Yes. Take light cuts (.015 to .030) and clean.
The reamer will always try to center it's self in the old chamber.
The reason for taking small cuts is so as soon as the pilot reaches the bore it will true up
any misalignment that may have existed in the old chamber.
You should not have any problems as long as you take it easy.
Good luck and have fun.
