Re: Anyone own a 7mm 300 Win Mag?
Broz, I have the numbers somewhere on exactly what you are gaining. I had considered having my .338 Win Mag reamed out to .338-300 Win Mag, but I was only going to get another 100 fps or so.
Running it through Quickload , real quick, I'm getting 3100-3150 with a 168 SMK with a 28" tube using RL22 & RL25. My guess is it will run 100-150 fps faster than a 7mm Rem Mag.
7mm RM with a 168gr SMK set at 3.4" has a usable case capacity of 75.645, using the .300 WM case at the same coal it shows 85.512
