The CP4 reticle is used to determine the
range of a target of known size. The example
below shows an 18” wide target bracketed
between the first two shorter vertical stadia
lines of the reticle. The distance between
these two stadia lines is 18” at 100 yds as
stated in diagram XX (which will be the
reticle diagram with dimensions).
The lower range scales is for bracketing a
32” tall target.
If you reference the MOA chart you will
see that the distance between the short
line at the top of the target and the bottom
horizontal line is 16 MOA.
The formula is then: 32 (height of the target)
÷16 (MOA from chart) x 100 = 200 yds.
AImING
The CP4 reticle can be used for aiming even
though it is not a bullet drop design.
To use the reticle for aiming you must know
several data points. First, you must know
the bullet drop of your specific cartridge.
For example let’s use M855 5.56 NATO. Zero
the firearm at 100 yds. Move to 200 yards
and fire a three to five shot group. Measure
the distance between your point of aim
and center of the group. Let’s say it drops
4.0”. You must then have a reference of a known measurement on the reticle to use
as an aiming point. In this case the center dot of the reticle measures 1.8” at 100 yds.
So at 200 yds it will be 3.6” (1.8” x 2=3.6”) which is as close to a 4.0” reference point as
you will get with the reticle. Hold over the height of the dot from your intended point of
impact at 200.
At 300 yds the M855 will drop approx. 15.2”. The measurement of reference “J” of the
reticle is 10.1” at 100 yds, so at 300 yds it is 30.0”. Use the halfway point of the vertical
stadia line as a hold point on the target at 300 yds.
