I would be happy with that accuracy and I think you found a good load. I use something similar in a sabot for my deer load. Since I can't use sabots when elk hunting in CO, I use the 338 gr platinum power belts and 100 gr of 777 in my encore. The average distance three elk traveled after being hit in the lungs was about 10 yards. The distances shot were 40 yds, 65 yds, and 124 yds. The bullets were complete pass throughs on two cows and was just under the skin on the off side of a 5x5 bull.
