I have a 30-06 and a 300 WSM High Country. My 06 likes 150gr SP's with IMR 4350 and groups are about 1 to 1.25 MOA, now the 300 WSM shoots between 0.5 to 0.75 MOA with 165gr SP bullets with IMR 4350. I did minimal load development on each; matter of fact for the WSM very little because I got lucky on my initial development. I have both triggers set at roughly 4 lbs. The 300 WSM is a real shooter out-of-the-box, I have shoot 1 MOA groups with factory ammo in the WSM. I push both of these rounds about 3000fps. I have killed 6 deer with 06 and 4 with WSM, all but 1 dropped on the spot. I have Vortex Vipers on both (06 - 6.5x20 and WSM 4x16).
