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?
range estimation can be done to what accuracy?
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?
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
