Horus H58 Reticle
 First Focal Plane
 Milliradian based
 gridded design
 designed for precise references for firing solutions and range estimation

elevation and wind on the H58 can be applied to what accuracy?
.1 mil

range estimation can be done to what accuracy?
.1 mil

what allows for accurate range estimation at any magnification?
the first focal plane (FFP)

The H58 reticle speed shooting feature is effective at what ranges?
250600 meters

How do you use the speed shooting portion of the reticle?
Flash mil the target utilizing the mil lines above the moving reference points, divide by 2.
Ex:8MPH ref line divided by 2 is 4 mil elevation

4 critical components necessary to calculate wind solutions:
 Actual windspeed
 Wind direction (value)
 Distance to target
 Cartridge BC and muzzle velocity

Why is the constant 4MPH significant to short wind formula?
 A 4MPH full value wind is required to move a .308 projectile (with a BC of .4 or more) 1 mil at 1000 yards.
 *(.9 at 900, .5 at 500, etc)

Clock positions for wind value that is 90% of full value?
2,4,8 and 10 o'clock

Clock positions for a wind value that is 70% of full value?
1:30, 4:30, 7:30 and 10:30

Clock positions for a wind value that is 50% of a full value wind?
12:30, 5:30, 6:30 and 11:30
