Interesting that's almost the exact ballistics for a 300 WSM with a 185 Berger. And does it a few grains less powder too, I guess.Why not a .270 Winchester. We've built a half a dozen that shoot the Berger 170gr EOL bullet at 2960fps. Tack drivers, low recoil, use it all day long on elk at 800yds. 2000fps and 1600lbs of energy at 800.
