[QUOTE="Triple BB, post: 541494, member: 947"] I copied this from a write up on another site. Still trying to figure what he's saying. Wish the author would've include a sample diagram. Anyone use this method? If so, how about more detail. "Another Rule-of-Thumb, suggested to me by Sergeant Neal Terry, a longtime sniper instructor and police SWAT sniper, is to draw an invisible vertical line through the up or down target, and where this line intersects the earth's surface, range it! Disregard the angle, ignore the direct distance from muzzle-to-target, concentrate only on adjusting elevation for the distance to where that vertical line touches the earth. Compensate for that distance, aim dead-on and fire. We've worn out several pads of paper comparing Neal's math to other kinds of up/down calculations - it works and it's the essence of simplicity!"
