Started messing around with this formula using my Vortex Viper HS-T set on 16 power. Target is 36in. tall set at 800yrds. Target is 4 MOA looking through scope. Formula is heigth of target x 95.5 ÷ MOA = yards. The yardage was shot in with my rangefinder. Equation, 36 x 95.5 ÷ 4 = 859.5 tell me what is wrong here. 60 yards is another 10 clicks for me and that is a little over 20in. drop. That my friend equals a clean miss. So is my rangefinder off or or the MOA on the scope or what. Just want a good way to a estimate yardage if the electronics fail. Thanks.
