RANGING WITH THE MRAD RETICLE
MRAD measurements are very effective
for ranging using simple formulas—
knowing the size of the target or nearby
object is essential.
= Range (Yards)
Target Size in Yards x 1000
Measured MRAD
= Range (Yards)
Target Size in Inches x 27.8
Measured MRAD
= Range (Meters)
Target Size in Meters x 1000
Measured MRAD
Be sure reticle is in focus before ranging.
Using either the vertical or horizontal
MRAD scale, place the reticle on the
object of known dimension and read
the number of MRAD spanned. Obtain
maximum accuracy in ranging by
calculating exact MRAD measurements.
Estimate MRAD measurement in 1/10
MRAD increments if possible.
Example: Ranging a 6-foot target (2
yards) at 4 MRAD yields 500 yards.
2 x 1000
4 MRAD
= 500 Yards
Accurate measuring will depend on a
very steady hold—be sure to use a high-
quality tripod. Once you have an accurate
MRAD reading, use the formula to
calculate the distance
