RR thanks for the tip but it took me 6 months to develop this load for this rifle. It pretty much shoots 1/2 MOA all day long. This group was .625" C-C and that was with a bit of a crosswind. With the 32X Mueller scope on it I was punching .45" groups at 200 yards with it which calculates out to about 1/4 MOA. So I stocked up on H4350 and pick up bullets and primers when I can.
