When I had the scope on the 7saum I had a correction factor because the scope was moving too far. I think now it is on a different rifle the 100yd zero is in the part of the scope adjustment where the clicks are 1/4 MOA but when I get past 700 I'm getting into the part of the adjustment where the clicks are more than 1/4MOA, probably closer to 1/3MOA.
To get to 700yds I need 14.7 MOA, to get to 800 I need 18.2 MOA, so an extra 3.5 MOA. If the clicks are 0.3MOA it will actually move 4.2MOA, which will be 5.6" high.
At 980 yds I need 25.1 MOA, which if the clicks are 0.3MOA would actually move 27.18 MOA, and I'd be 20" high.
This pretty much agrees with what I've seen in practice.
So i've got to do the check against a grid to see where the click values change, if they do.
