I’ve been toying with Hunter and 160 Sierras, results so far have been good, though best accuracy has been on the lower end (~2450 fps). I am using a magnum primer.
I haven’t gone higher than 46.0, which produced an average velocity of 2525 fps out of a 22” M70.
Based on my rifle, I still believe 4350’s are a better bet. Might go back and work up slightly from 46.0 for Hunter though.
