Holdover For Compensating Bullet Drop
To be able to use the elevation holdovers eectively, you have to know
the distance to your target and bullet trajectory (bullet drop in inches or
mils). Since most of bullet ballistic charts highlight bullet drops in inches,
you have to know that, 1 mil equals to 3.6 inches at 100 yards, 7.2 inches
at 200 yards, and 36 inches at 1000 yards, etc.
For example, under no wind condition, if you knew your target is at 500
yards and your ammo has a 54 inch bullet drop at that distance, you want
to use 3 mil holdover point. Here is how you got the 3 mil: since 1 mil
equals to 3.6 inches x 5 = 18 inches at 500 yards, and then 3 mils equal
to 3 x 18 inches =54 inches at 500 yards, you want to hold the 3 mil drop
point to compensate the 54 inch bullet drop.
To achieve ultimate precision, it is always a better idea to develop your
own D.O.P.E (Data of Previous Engagement ) chart so that you can refer
back to it for specic bullet drop compensation under dierent ambient
environment and weather condition.
Example
3 mil /54 inch holdover for a target at 500 yards out. No wind.
