Close. A 20 moa cantered rail would be a little off, thus I use...

Formula= (Scope's "Tube Diameter"\2) + (Bolt's "Diameter"\2) + (Distance between bottom of scope tube and top of bolt in middle of tube area equally between ring mounts) = Scope Height!

Just as C.O.Shooter posted!

My best guess would be that the optically correct location to measure the height to would be the center of the exit pupil (if you can find it).

Well said!

Out of curiosity, I just ran the data, on Exbal, for one of my rifles at 1000 yds. The elevation at that distance came back as 28.25 MOA. I then went back and only changed the scope height from 1.75" to 2.0". That elevation came back as 28.0 MOA.

1/4 MOA change at 1000 for a 1/4" difference in scope height.

I just wish I had a place to shoot at 1000 to demonstrate it!

As previously mentioned, measuring & adjusting to fit dope seems to work the best for me. I measure at the turrets, then tweak it to fit actual poi at range
