Re: Loading for .300WM - Ideas?
I have a custom built 300 Win Mag and it likes 71.0 gr of IMR 4831 with the 190gr SMK in WW brass and CCI mag primers.
MV averages 3031fps, average of 10 shots.
Re: another 300 Win Mag load question
I have a custom Mauser action with a 27.5" barrel that really likes the
Sierra 190gr Matchking bullet with 71.0gr of IMR-4831 in WW brass and
CCI magnum primers.
Average velocity for 10 rounds is 3031fps.
