    Don't get too wrapped up in this figure. It doesn't make a lot of difference. I just went to http://www.vortexoptics.com/content/lrbc and entered the following info:

    Factory Ammo - Black Hills Gold .308 Win 168gr AMax
    100 yard zero
    4550ft elevation
    45 degrees, 58% humidity, 25.47" pressure

    Scope height - 1.5" - 1,000 yard drop = 35.5 moa
    Scope height - 2.0" - 1,000 yard drop = 35.1 moa

    Try it for yourself. I leave the scope height at the 1.75" default anymore. Worry about reading the wind and not scope height in tenths of inches. One less thing to worry about.
