LIT. #: 98-0397/03-04 MIL DOT RIFLESCOPE INSTRUCTION MANUAL 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 Object's Width Or Height In Mils = Range In Yards 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 2.5 mils 1330 = = 532 Yards 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.
