This process works well for many cartridges and weapon systems,but not all will impact exactly the same. However this system should
place you close enough to make a solid hit, all else being equal. If shooting with a different caliber or muzzle velocity, you may need to
add to or subtract from the original elevation hold to adapt the formula for your needs.
CALCuLATing hoLdS FoR Moving TARgETS
The H59 reticle has a series of even numbers above the main horizontal stadia.
These numbers represent speeds for moving targets at 2, 4, 6, 8 and 10
mph, with additional holds starting at 20 mils and continuing every 10 mph
thereafter to the left and right. These speeds are optimized for .308 caliber, but
may be used with many other calibers.
To hold on a target moving at one of these speeds, simply hold the portion of
the horizontal stadia that intersects with the short line nearest the number
representing the target speed over the moving target, accounting for possible
adjustments for distances different from optimal. If using the Horus grid (below
center) for elevation, use a hold point in line with the appropriate speed. To hold
on a target traveling at a speed between markings (such as 5 mph) you hold
between the even numbers on either side of it (4 and 6 mph).
