APPendIx: USInG MIL dOT ReTICLeS
some models of the elite riflescope contain 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.
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 on the next page. 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 (be sure to set it on the synchronized magnification setting-see below for more info), 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,
a mistake in 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
all elite scopes with mil dot reticles have their reticle in the second focal plane (the reticle stays the same size regardless
of magnification). therefore, the power selector ring must be set at the designated, calibrated power (indicated by a
dot or red color for the magnification number on the power ring) to synchronize the mil-dot size for ranging. but
you also can range at half that power if you divide the range estimate in half, or at double the calibrated power, by
doubling the range estimate, as shown in the next section (using as an example a 2nd focal plane reticle with a calibrated
(synchronized) setting of 12x power):
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.
