3 mil / 54 inch holdeover for a target at 500 yards out. No wind.
Example
Holdover For Compensating Bullet Drop
To be able to use the elevation holdovers effectively, you have to
know the distance to your target and bullet trajectory (bullet drop
in inches or mils). Since most of bullet balistic chart highlight
bullet drops in inches, you have to know that, 1mil 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 yeards,
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 specific bullet drop compensation under
different ambient environment and weather condition.
