HOW TO USE THE RANGEFINDER RETICLE
A Rangefinder Reticle
contains either two or more
horizontal lines placed at given
distances away from each other or
a horizontal line that is a certain thickness.
The distance between the lines, or the line
thickness, when placed against an object of known
size, such as a game animal, will closely approximate
the distance from the shooter to the target. The shooter
then uses the lines to properly adjust the point of aim so
as to align the point of aim with the intended point of impact.

FIGURE 1.
1. First, it is necessary to know the magnification of your scope at
the moment you look at the target. As an example, an 8-32x50
scope can have magnifications from 8x to 32x. At a setting of 8x,
you have Power = 8.
2. In addition, you need to know the actual target size. For
example, a deer that is 4 feet tall fits into 4 increments of "A" in
the reticle (See Fig. 1). That means each increment of "A" is 1
foot long at the target. So, you have A=12" (it must be in inches).
3. Here is the formula to use to calculate Range:
Power x A (inches) x 2.5 = Range (yards)
So, in the example, 8 x12 x 2.5 = 240 yards.
Therefore your target is 240 yards away.
DETERMINING RANGE USING MINUTE OF ANGLE (MOA)
1. The vertical line of the reticle is divided into 2
MOA increments (approx. 2" @ 100yds). These
vertical increments are used for range estimation,
multiple zero points and accurate bullet drop
compensation.
2. Any size target can be easily ranged using a
simple formula:
Target Size In Inches .. MOA x 100 = Range In Yards
3. For example, the target is 18" high and the target's
height measures 6 MOA. The range to the target is
300 yards (18" .. 6 MOA x 100 = 300 yards).
4. Once the range is determined select an appropriate
hold point based on the bullet drop of your
cartridge. The vertical spacings can easily be split
into 1 MOA increments further enhancing long
range accuracy.
