USING MIL DOTS
Your new Bushnell riflescope contains a mil-dot reticle, the most
accurate means of range estimation using a manual optical device.
These mil dots also allow precise leads for moving targets and exact
compensation for shooting in a crosswind. The zoom ring 9x marking
is red instead of white because this is the synchronized magnification
for ranging on these mil dots.
RETICLE DESCRIPTION
The middle of this reticle contains four evenly spaced mil dots arrayed
outward vertically and horizontally from the center. Actually, because
the very center dot was left out to allow clear aiming, the reticle
represents five mils in any direction -- ten vertical mils -- as shown in
the illustration. Note that the most outward dot is replaced by the
edge of the heavier reticle line.
One mil is the space from center-dot to center-dot. One-half and
one-quarter mils are easy to estimate mentally; with practice, you can
measure tenths of mils for the most exact ranging.
RANGING WITH YOUR MIL-DOT RETICLE
The mil is an angular measurement -- 1/6400th of a circle -- which
equals almost precisely one yard at 1000 yards, or one meter at
1000 meters. This proportional relationship makes possible a simple
formula to compute distances:
The Measured Object’s Width
Or Height In Yards x 1000
= Range In Yards
Object’s Width Or Height In Mils
This formula works equally well with meters, but don’t mix meters
and yards: Measure the object in yards to find the distance in yards,
use meters to yield distances in meters.
Looking through your scope, set at 9x, select an object at the distance
you want to range -- an object whose width or height you know or
can estimate accurately. Man-made objects of uniform size, such as
fenceposts, are best, but any object of known dimensions will do.
Measure the object’s height or width carefully in mils, compute it
according to the formula and you will find its range. Support your
rifle and be precise when measuring objects; any measuring error
causes an error in the computed range. Equally, mis-estimating the
object size results in a proportional range error.
Here’s an example:
A coyote is sunning himself in a snowfield beside
a fencepost; having crossed the fence earlier, you know that the post
is four feet high, or 1.33 yards. The fencepost measures 2.5 mils in
your reticle.
1.33 yards x 1000
1330
= = 532 Yards
2.5 mils
2.5
Since this is a variable power scope and the reticle stays the same size
no matter the magnification, it must be set at the 9x index dot to
synchronize the mil-dot size for ranging
CALCULATING HOLDS FOR WIND AND MOVING TARGETS
Your horizontal mil dots provide a precise way of holding for
crosswinds and target movement. Just look in your cartridge’s wind
drift and moving target tables to determine the exact holds for
different distances. The accompanying table lists one-mil widths from
100 to 600 yards, so you can calculate how many mils to hold right or
left when firing in a crosswind, or engaging a moving target.
One mil is the distance between center of dots. It’s easy to measure
in half-mils or even quarter-mils but with practice you can measure
tenths of a mil.
MIL WIDTH FOR WIND AND MOVING TARGET LEADS

100 Yards 3.6” (0.1 Yard)
200 Yards 7.2” (0.2 Yard)
300 Yards 10.8” (0.3 Yard)
400 Yards 14.4” (0.4 Yard)
500 Yards 18.0” (0.5 Yard)
600 Yards 21.6” (0.6 Yard)
