I also have an SFII. It would shoot about an MOA until I bedded the action. That got it down to 1/2 MOA right away. I am about to start working up loads for match bullets, but with 74 gr. of IMR4350 I am getting 1/2 MOA with Speers 150 gr SPBT.

About to try H1000 and 168 Berger VLD. Am going to the range tomorrow to try out 5 different loadings. I am hoping to shoot 500 and 1000 yards, and am working up loads for this. Will try 180 gr bullets next.

Just try different bullet, powder, primer combinations and go with what works.
