SAS, the results are exactly what I expected. I am neither excited nor disappointed. I would have been thrilled with 1.5 MOA. I agree with you, round groups are more better!

I'm sure tweaking loads will shrink it. I might run a group of 175 smk's just for kicks.

In its current form it will make a fine MPBR rig which in reality is what 5 lb rifle is designed for.
