I shoot the 250 grain sst with 46 grains of IMR 4227 with the mmp sabot,tried other combos like the barnes and i dont remember which sabot now but they would barely make it out of the barrel.Accuracy is about 2-3 inches at 100 yards. Hope you get it worked out.
That is PRECISELY the load I shoot. I have a Leupold 2x7 x 28 scope mounted on it. Mine will consistently group 1 1/2" or LESS at 100 yards rested. Mine is also the non accu-trigger 10ML-II.
