Ranging a 6-foot target (2 yards) at 4 mrads yields 500 yards.
Example
2 x 1000
4 mrads
500 Yards
=
Target Size (Yards) x 1000
MRADs Read
Range (Yards)

To use these formulas, you will need to know the measured
size of the target or a nearby object. Using either the vertical or
horizontal mrad scale, place the reticle on the target of known
measurement and read the number of mrads spanned.
Accurate measuring will depend on a very steady hold—the rifle
should be solidly braced using a rest, bipod or sling. Once you
have an accurate mrad reading, use any of the listed ranging
formulas to calculate distance.
Maximum accuracy in ranging will be obtained by calculating
exact mrad measurements—mrads should be estimated in tenths
if possible.
Ranging
Mrad reticles are very effective for ranging using simple formulas:
Target Size (Meters) x 1000
MRADs Read
Range (Meters)
=
Target Size (Inches) x 27.8
MRADs Read
Range (Yards)
=
