7mm rem mag, savage dbm and berger bullets
Ok I am building a semi-custom savage dbm 7mm rem mag and am wanting to use berger bullets
Q-1 I don't know what bullets will fit loaded into my mag with enough room for powder. I have 3.5'' of length in my mag to work with, what bullet should I start with?
Q- 2 what is free bore and how much should I have my gunsmith put in and what reamer should he use to chamber the barrel just a normal 7 mag or something different? I would still like to have the option of shooting normal bullets.
