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?
