[QUOTE="greenejc, post: 2339081, member: 60453"] Actually the horizontal leg distance is what you use. That's because an angled (up or down, it doesn't matter) shot gets an assist from gravity. The reason there are charts is because that assist is constant, due to the gravitic constant. The military uses this constant to determine maximum ordinates for artillery, rockets and mortars. In world War I, they used tables and bullet weight/B.C. to determine what angle to fire massed machineguns at targets such as road intersections and other open targets. They could put massed fires on targets as far out as 4500 yards. It was quite effective. The angle off of horizontal effectively flattens the trajectory. [/QUOTE]
