Ranging with mrads
Mrad measurements are very effective for ranging using simple
formulas. Knowing the size of the target or a nearby object is
essential to using these formulas.
Using either the vertical or horizontal mrad scale, place the
reticle on the target of known dimension and read the number
of mrads spanned. Obtain maximum accuracy in ranging by
calculating exact mrad measurements—try to estimate mrad
measurement in 1/10s if possible.
Range (Yards) =
Target Size (Yards) x 1000
Measured mrads
Range (Yards) =
Target Size (Inches) x 27.8
Measured mrads
Range (Meters) =
Target Size (Meters) x 1000
Measured mrads
Accurate measuring will depend on a very steady hold. Be
sure to solidly brace the arms when measuring or use a tripod
mount for maximum accuracy. Once you have an accurate
mrad reading, use one of the formulas to calculate the
distance.
Ranging a 6-foot target (2 yards) at 4 mrads yields 500 yards.
