I have a Model 12 Savage 22/250 with a 26 inch, bull barrel 1 in 12 twist. I would like to know what bullet weight would be most accurate at 100, 200 and 300 yds.? Would a heavier weight give me more accuracy at even longer ranges ? Right now I have 10 boxes of 55 gr PSP in three different mnfgs. I was somewhat disappointed the first and only time I shot the rifle as the best group I could get was about 1 moa. I know that gun should be capable of shooting better. There was a slight breeze, 5 mph at my back that I didn't think should effect it that much.
