It's just fine for a precision shooter to calculate a moving target's compensation down to the closest half inch, but it's tough to actually shoot this way. A simpler means of applying moving target compensation goes all the way back to the days of musketry and is called, appropriately, using "leads."
Our forefathers knew chat it was hard to estimate what an inch looks like against and in front of a distant target, especially a moving one. So these frontiersmen applied Yankee ingenuity and decided that a man was 12 inches wide—1 foot—when looked at from the side, as we've illustrated. This became one "lead."
Looking at our .308 168-grain/Ml 18 data, therefore, instead of leading a 100-yard walking man by 7 inches, I use half a lead, which is measured from the cemcr of his body. My aim point becomes the edge of his body in the direction he's moving, which means although a perfect lead should be 7 inches, I'm using only 6 inches and will be 1 inch off—a tiny compromise to make considering how clearly my mind's eye can tell me to aim at the leading edge of his body. If he was walking at 500 yards, I'd hold 6 leads ahead of his center, equal to 36 inches.

Deer hunting is an interesting thing that reminds you of those golden old ages of 19th centuries, where a handsome hunk well equipped with all hunting material rides on horse searching for his target animal either for the purpose of displaying his masculine powers or for enticing and wooing his lady love.
