[QUOTE="LouBoyd, post: 671135, member: 9253"] 12 inch of horizontal error for a 6 degree cant indicates a drop of: 1/tan(6) * 1 ft = 9.51 feet The time for gravity to cause a 9.51 drop =16* T^2 so T = sqrt(9.51/16) = .77 seconds. So shooting a 0.60 BC bullet at 3312 fps or a 0.70 BC bullet at 3218 fps would give 0.77 seconds time of flight at 700 yards an the horizontal errror discussed above. Cant error, like drop, expressed as an angle or linear measurement is directly proportional to the square of the time of flight. [/QUOTE]
