Long Range 101 Part 84 - How Mil-Dots are Used for Ranging Targets

Ranging targets with your scope reticle discussed in detail.

Ranging Formulas:
Target size (any unit) x 1000 / Mils = Range (any unit)
Target Size (inches) x 25.4 / Mils = Range (m)
Target size (inches) x 100 / MOA = Range (yards)

HOW TO USE:
Collect and record the dimensions of various potential TRPs (target reference points) in your dope book. Try to anticipate any possible objects that you may see in your AO that could be used to range distances to various TRPs on your range card.
Draw up range card... designate and range all your TRPs ahead of time. This will enable you to deliver fire very quickly when a target presents itself in proximity to a TRP at a predetermined distance.

If target presents itself at an unknown range, you may have to range the target itself (assuming you know its dimensions).

Advantages:
Positive range bracket acquisition
Passive range finding system (does not emit light)
Mils are always available -- can't loose your optic
Not battery dependent -- can operate for extended periods w/o battery resupply

Limitations:
Have to know target dimensions
The full known dimensions of the object being ranged must be visible and should be situated perpendicular to the range finding device
Requires extreme steady position
Only relatively effective out to 700 yards for most applications
Typically takes 10 -- 30 seconds to accomplish

When to use Ranging Reticles:
At a minimum, an optical trigonometric confirmation of any target's range should be performed when time allows -- don't trust LASER or GPS readings alone.
Use in situations where use of LASERs may risk enemy detection.
Although reticles will have somewhat limited use at longer ranges do to error probability the ranging reticle will be your PRIMARY RANGING BACKUP & CONFIRMATION METHOD.
