55 grains of H4350, gave me an average of 5/16 inch groups.
57 grains of 4831 gave me a 3/8ths inch group, always with one flyer.
These were 100 yard groups and were with Sierra 168 grain HPBT, they were pretty hot and I would suggest you work up to them.
58 grains of 4350 would stick a case but shot very well.
Those were the two powders that shot best in this rifle, groups were shot in 1976.
Hope they work for you!
