Using the Razor HD 30x R/T Eyepiece with MOA Ranging Reticle

Use the reticle focus to adjust
the reticle image sharpness.


To fine tune the reticle
orientation in uneven tripod
conditions, rotate the scope
using the Razor HD’s tripod
collar adjustment.

This MOA-based Razor HD reticle can be used to estimate distances (see back) as well as to call shots and
provide rapid MOA corrections for stray shots. It will be be most useful when used in conjunction with
MOA-based riflescopes.

The reticle also supplies quick-ranging brackets based on target objects spanning either 9 or 18 inches. For
example, 18 inches would span the back-to-brisket dimension on a typical whitetail deer. To use, simply
match the closest bracket in size to the object known to span 9 or 18 inches and read the matching yardage
in meters (1 meter = 1.1 yards).

Using either the vertical or horizontal MOA scale, place the
reticle on the target of known dimensions and read the number of
MOAs spanned. You will obtain maximum accuracy in ranging by
calculating exact MOA measurements. MOAs should be estimated
in 1/4s if possible. To help calculate fractions of MOAs, the inner
crosshair line thickness can be used as a reference.

Example:

Ranging a 6-foot target (72 inches)

at 12 MOAs yields 500 yards.

Accurate measuring will
depend on a very steady
hold—be sure to use a
high quality tripod. Once
you have an accurate MOA
reading, use the formula to
calculate the distance.

MOA measurements are very effective for ranging using simple
formulas—knowing the size of the target or nearby object is essential.

Note: In the MOA ranging formula, a shooter may substitute 100 for 95.5 in
the interest of speedier calculations. Be aware that this will produce a five percent
over-estimation error of the yardage distance obtained.
