I normally zero my rifle at 100m, and shoot at metal targets whether they be circles or a ram-shaped target at 500-600m. If I get a chronograph and it measures to what ever the muzzle velocity, how do I determine how much it drops out to 500-600m. Is there like a special mathematical equation of sorts to figure this out?
