Ranging with MRAD
MRAD measurements are effective for ranging using a
simple formula. Knowing the size of the target or a nearby
object is essential to using these formulas.
For the most accurate solution, use the longest dimension.
If the object is taller than it is wide, it is best to use the
object’s height in the formula. Using either the vertical
or horizontal MRAD scale, place the reticle on a target of
known dimensions and read the number of MRAD spanned.
You will obtain the best results if measured to the nearest
1/10
th
MRAD.
Accurate measuring will depend on a very steady hold. The
optic should be firmly braced using a rest or a tripod. Once
you have an accurate MRAD reading, use the formula to
calculate the distance.
