Theoretically a 270, 300 mag and a 375 would do it.
I do it with;
1. A pre war Mod 70 .30-06 blued with a Rimrock stock, Warne bases with the built in peep sight rear. Warne QR rings and a 3x9x40 oldstyle matte Vari-X 2.
2. A .30-06 SS Model 70 FW "All Terrrain" with the plastic stock. I added iron sights. It has Weaver bases and a new style 2.5x8 Leupold Scope.
3. A .338 Win Mag SS Model 70 Classic shortened to 23 inches with a KDF varmint brake [that was a waste of $200] I don't use. Iron sights added. Warne Premier bases and rings again with the built in peep. Scope is an old style Vari-X 3 2.5x8 Leupold. I had to change to a Mc Millan stock to get this gun to shoot to its potential.
