I have not done that yet, however, while fire forming I tried 75 - 90 grains and found better groups with the 90 grains. However, that's a good point, will mount the scope and try some different loads again at various ranges for groups and get the Oehler out and record velocities.

Recoil from the bench is pretty stiff but not bad at all off the sticks with the slip on spongy pad.

Did get a few rounds shot today at 1K off sticks, once on target all stayed well within the white, a 40 inch circle on a 72 inch square gong. So all is coming together well with this rifle and makes me happy!
