User manual BUSHNELL TROPHY MIL DOT

[. . . ] #: 91-0272/10-01 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. [. . . ] 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 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 2. 5 1330 = 532 Yards Range In Yards 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.

[. . . ] 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. www. bushnell. com [. . . ]
