I'm running 72gr H4831 CCI 250 Hornady brass .050 jump. I have varied loads and jump....remember the mag does come into play, though I have been feeding it single action. The rifle is doing 2-3 MOA @ 100yrds. With a #2 contour barrel I would expect a lot better???
By chance are you using a brake? I have a brake on mine and that helps me, (mostly for spotting my own shots at longer distances). Also, don't take this wrong, but maybe recoil affecting some with accuracy? I'm wondering about copper fouling also. How many rounds through the tube? Maybe try cleaning the barrel and then see what happens if you haven't done so.
