Does it do it through the whole adjustment? At 8 MOA is it half as big of group? If it were bedding or an issue with the rifle you would see it throughout the adjustment. It might be an issue with the scopes erector setup.
At 600, it seems to be about 1 MOA right of my wind call. 1/2 MOA of that should be spin drift so there is somewhere between 1/4 and 1/2 MOA misalignment. You answered what I was asking although I would like a few more responses. Getting it much better than I have it may be chasing my tail.
It isn't a rifle issue, it seems to be a scope issue. I don't get any of the horizontal dispersion when I add elevation. The last 3 shot group I shot with 9 MOA on was slightly over 1/4". I thought about getting a 10 MOA rail, but it would raise my scope which I don't want to do. Plus, I may have to screw with the crosshair alignment again.
