[QUOTE="Blaine Fields, post: 30738, member: 183"] You aren't going to get the correct drop value by simple multiplying the path by the cosine of the shot angle. The formula is: path = -(drop * cos(a) + scope height) + ((zero drop + scope height)* (range/zero range)) Another point: there shouldn't be an appreciable difference in the path whether the shot angle is positive or negative. It's odd that JBM shows a 5" difference. [ 01-19-2004: Message edited by: Blaine Fields ] [/QUOTE]
