Thanks. I knew H4350 is the go to power, but all I have is H4831SC. My current load is Amax 140gr 0.01" off the land, 46.8gr H4831SC, 210M, 2833 FPS. 5 shots group are about 0.56-0.66MOA. Not bad, just not as tight as NCC 140gr.
What bothers me is 3 shots around 0.2MOA, then next two shots open the groups up to 0.6MOA, there is definitely room for improvement.
