If I were buying ammo and using the 30-06 out west, I would use the Federal Blue box 150 grain cartridges. The ones loaded with Speer grand slams. I used them on prairie Mules last year. The did plenty but not excessive meat Damage and chronographed 2940 from my 22 inch barreled 7600 Remington pump. They also grouped under 1 1/2 inches. The box says 2910 and they surpassed that in my rifle.
