I shot this load yesterday. 40.5 grains of the pull down powder. Accuracy was excellent. while the group was 4 inches it was a straight line string vertically. You could have put a straight edge along the holes. 10 shots in that group. The string is my fault. I can see well enough to keep the windage on but elevation I have trouble with. Old eyes I guess.
I think the big difference in the load was that the military load ran in a .3 grain variation and the old hard primer was inconsistent. I tossed exactly 40.5 grains and used a new primer.
I also shot a varget load with that bullet. Not good at all. Now I'm sorry I burned off that powder from the first batch.
