I just started reloading 30-06 and I have a Rcbs JR3 press and I bought a set of Lyman All-American full length dies. I have a Lee shell holder. When I set my die, I raise the ram all the way up and screw the die down until it contacts the shell holder hard. After I size the cases and put them in my savage axis the bolt will barely close. It seems I need to bump the shoulder back a few more thousandths. Could I just grind a few thousandths off the end of the die to allow for setting it a little closer to the shell plate. I am a machinist so I would be using a precision grinding machine.
