[QUOTE="Casing, post: 514667, member: 17014"] I shoot Nosler brass, Nosler 140 grain Accubonds with 59-62.5 grains of H4831sc. I get the best accuracy with 59 grains and then close to the same accuracy with 62.5 grains H4831sc at 3050 fps. My groups open up a little in between these two weights. I was shooting Federal 210 match primers and seemed to get a slight flier or a shot out of the group every now and then. I switched to Win LR primers and my problem went away. 5 shot groups under 1/2". This is the ultimate caliber, I love it! RL 22 is also a good powder for this caliber but it is so temp. sensitive I got away from it. I was getting good groups in the warmer months and then when cold weather came in my point of impact would move almost 3 inches!...........I would have to say H4831 is the go to powder for the 280 AI.
