USING THE MIL DOT RETICLE (ET3124F / ET6245F)

Your Bushnell riﬂescope contains a mil-dot reticle (1st focal plane), 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 ve 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 nd the distance in yards, use

meters to yield distances in meters.

Looking through your scope, 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
