[QUOTE="speedengineer, post: 1981671, member: 112986"] Stgraves, While the chart you referenced isn't wrong (and is a helpful contribution to this discussion), you are indeed using it incorrectly. What that chart does is allows you to easily calculate the horizontal distance to the target, knowing the shot's inclination angle and line-of-sight distance. This horizontal distance to the target is then typically used with a range card to get the values for bullet drop. Instead of looking up the bullet drop on the card for 500 yards line-of-sight, you'd look up the drop for 499.5 yards of horizontal distance (for 2.5 degrees inclination). For this case with such a small inclination angle, this would give pretty much the exact same answer for drop value. Using a ballistic calculator with an input for the shooting angle is a more accurate solution, especially for high inclination angles. The old school quick n dirty chart method will get you close....but only if you use it correctly!!!!! [/QUOTE]
