[QUOTE="BrentM, post: 770740, member: 61747"] Thought this over a bit and decided to throw out a couple of numbers: 1050 yards. 267 inches drop. 24.3 MOA- 0 degree slope Variable is 35 degree slope. Conventional cosine angle says 861 yards. 17.3 MOA (1050x.82=861) ACI x drop says 975 yards. 21.4 (267x.82=219) 219 drop = 975 yards Shooter says 19.2 MOA 17.3 ACI 21.4 drop x aci 19.2 shooter Max spread is 4.1 moa. Difference between horizontal and computer is 1.9 MOA. That is if I did the math right. So that would suggest if you simply took the ACI x yards you could be at least 1.9 MOA or 19 inches low vs a computer program. I am not convinced the ACI x drop is accurate yet. That is incredibly steep angle to only pull 75 yards off the entire number. I am thinking your impact would be high. OK. If I did this all correctly and the slope is now 15 degrees, fairly normal slope...... 22.7 ACI x yards = 1008 23.7 1034 yards or 256 inches drop 23.4 shooter Max spread is 1 MOA. .5 ACI vs shooter. Clearly the steeper the angle the greater the difference. What I don't know is if my Leica will give a horizontal distance = to ACI x yards. This I must find out. I wonder how the G7 handles this equation. [/QUOTE]
