my buddy, a damn good shot and he knows his stuff. Was 81 degrees, at sea level BP and humidity were stable. Target at 835 yards he was hitting about 2 MOA high, with a 260 match. Recalculated everything and still hitting bout 2 moa high. The kicker- 700 yards of this shot was over water. We know that the humid air weighs less than dry air...
My question how do you calculate for this? What is the part of the equation that I am failing see?

THIS EXPLAINS IT ALL!!
Don't understand it but if I had to guess I would guess it is the inaccuracy of the MOA adjustments in the scope. If it is supposed to be .25 MOA per click and is off that measurement by even a small margin it could account for several inches at over 8 football fields away.

or was he using MOA on his drop chart, but the scope adjustments were in inches?
Really?
Warm air is lighter than cold air, and I expect humidity would make the air even heavier.
