Did some internet digging and came up with a few different loads I wanted to try. I loaded up a few groups and hit the range.
With a freshly cleaned bore, I put the remaining Fed 168 GMM through the bore to foul it before testing. The group reported was the Clean Cold Bore, the rest of the groups hovered around the 1 - 1.25 MOA mark. This also served as baseline to see if I could hold the same groups as when I had the 20x scope on it. Comfortable with the results, I started the testing.
*All groups were shot with a Trijicon 4x. This is what the rifle will be setup for, a light easy to handle rifle good for 500m.

This barrel seems to be sub-MOA capable with the right ammo, and will shoot anything you throw at it around 1 - 2 MOA mark.
I not done testing just yet, I will post more as I go on. Almost there.
