handloading 300wsm

I recently bought a winchester mdl 70 coyote in 300wsm. second box of bullets were federal premium factory ammo and groups were around 1moa. since then a friend and I have been trying to work up a load for it and I wanted to shoot 180 gr accubonds. I have all but given up on getting the accubonds to group as we have tried several different powders with nothing grouping under 1.5 moa. does anyone have any suggestions?

    Try 65-66grs of Reloader 17. It is the best performing powder in the 300wsm with 180's. I am getting 3180fps out of a 26" barrel with 180's. I have had really good luck with Supreme 780 too.

    I've been using H-4350 with both 180 Nosler Ballistic tips and Berger 185 VLD's with sb-MOA results @ 2995ft/sec .

    I'm getting good groups with 165gr Hornady Interbonds with 69.0grs of Winchester WXR or Reloader-22 and also 65.0grs of IMR-4350.

    H4350 and RL17 are good powders in the 300 WSM. RL17 will get you a good bit more velocity. I would say just keep trying different combos of bullets and powder until you get a good one. And make sure your loading procedures are accurate and consistant.

    I am using 65 grains of h4350 loaded to 2.855 oal with 180 ct ballistic silvertips in my tikka and its a .5" gun. Attempted the accubonds which look the same but cost twice as much and best group I could get was 2+" I was so disgusted I did not even measure it I just switched back to my cheap highly effective bullets. I have not had anything yet that shot the accubonds well.
