ATN RANgEFINDER RETIclE
The rangefinder reticle in your riflescope was designed to
assist you in determining the range of your target. These dis-
tances are based on a 6’ target, if a 6’ target fits between the
numbered baseline (the five short horizontal lines) and the
post of the reticle above the baseline determines your dis-
tance. If a 6’ target fits between the horizontal post of the ret-
icle and 2 the target is 200 yards away. If the same target fits
between the 4 and the horizontal post of the reticle the target
is 400 yards away. The same is with the 6 and 10. The target
would be either 600, 800 or 1000 yards away.
mIl-DoT RETIclE
Mil dot reticle is a reliable mean for determining distances to targets, introducing leads for
moving targets, and for alternate aiming points for windage and elevation holds.
Look through the scope, and bracket the object between dots. The space between dot
centers subtends one milliradian (mil). One mil. subtends 3.6 inches at 100 yards or 36
inches at 1,000 yards. To use this system effectively you must know the size of the target.
By measuring the height or width of a known (or approximately known target size) in mil-
radians using the reticles, the target distance can be calculated as follows.
R = range in meters, H = target size in meters, M = mil-radians of the image size:
R = 1000 * h / m
Military shooters are trained to know that the
common male torso is 39 inches from crotch
to top of head. This is very close to exactly
one meter. This formula then becomes
R = 1000 / m
for a one meter target size.
All of the following formula are equivalent to
the one above for estimating range.
R = range in meters, H = target size in inches,
M = mil-radians of the image:
R = 25.4 * h / m
R = range in yards, H = target size in inches,
M = mil-radians of the image:
R = 27.78 * h / m
R = range in yards, H = target size in feet,
M = mil-radians of the image:
R=333.3 * h / m

The 4-12x also comes standard with a 1000 yard bullet drop compensator for the .50BMG
round. The 2-6x also comes standard with a 500 yard bullet drop compensator for the
.223 round. You should have zeroed your scope at 100 yards target for 2-6x68 and a 200
yard target for 4-12x80. When shooting at longer ranges the bullet drop compensator can
be adjusted for 200, 300, 400, and 500 yards. Pending on the distance click the bullet
