Thanks to all for reply!
Choosing the round is the first of a number of questions I have. The Mauser was brought back from WWII by my uncle who gave it to me while I was in high school 55 years ago. I want to upgrade it before giving it to my son.
The next step is choosing the barrel. It will be either .243 or .308.
I would like to buy a short chambered, finish blued barrel that will require only hand reaming to headspace exactly. Should it come cut so as to bottom up on the primary torque ring with minimal gap to the receiver?
Can a supplier be recommended?
