I got the bottom of my accuracy issue. It was not the powder, but it was the Bullets. It was recommended to me to try the Nosler 300 grain partition in a black sabot that Nosler sells. They did not like my gun at all. About every third shot at 100 yards would totally miss a 2'x3' target. I cleaned it up again and switched to some 295 power belts and my groups went to sub 2". I guess with my cheapo CVA pre-buckhorn, its gotta be powerbelts. I have shot the 245s in it well also. The whitehots seem to be fine anyway with equal accuracy to the 777 I was using.
