Re: Am I missing something?
What am I missing here?
Well, a Dastardly Daesh at 3500 yards (unless you happen to be this particular Canadian sniper, which I doubt). And drag. The vertical component of the bullet's speed is not affected by gravity only but by the vertical component of the bullet's drag, which decreases with at least the square of the speed (and probably some higher-order factors). So you're not dealing with a pure parabola, and you would have to wrangle some fierce higher-order equation series to get at the right answer.
