    Get away from the CCIs.

    Fed 210 or WLR generally works the best in the WSM.

    I recently worked up a load for a buddies .300 WSM using 165gr's. I tried every load that was in the Nosler #5 manual. Nothing seemed to work in his A-bolt. I eventually went to a max load of RL22 and Rem 9.5M primers. Three shots, one hole. He was pleased and I was tired of the recoil.
    I don't think there is a listing for RL22 under the 165gr so I did the math and came up with 70gr as max. However, 69gr shot the best in his rifle. Hope this helps. Johnny K.
