and I've yet to see anything I've tried it in shoot superformance, so moa out of superformance is pretty good imo, I would grab some 168 eld-m white box hornady match and all 3-Fusion weights, plus a box of or two of the federal blue box usuals and go 3-shot group comparing between them with that rig, those are standard knowns to shoot well in most things
if you get bored and want even less recoil and muzzle jump for more fun on running deer etc. you're pushing 30-06 levels there, that thing would be a peach with standard velocity stuff and make follow ups not just fun but why not get your money's worth and sink as many into em as you can
