71 grains of H4831SC seated .01" off the lands worked best for me. RL22 gave pretty good results, and H1000 did not for me. However, I use the 200 grain SMKs, and I have been so happy with how they shoot I am going to try them for my extended range elk hunts
first instead of the accubonds. If I have problems, I'll switch back to the accubonds. For the SMKs, I am at 71.3 grains H4831SC .005" off the lands, and this load produces .3" groups when I don't screw it up, and RL22 did only half that good. H1000 did not do good at all with the SMKs, at least up to 78 grains.
