Looking through your scope at the synchronized magnication setting, 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 fence posts, 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 nd its
range. Support your rie and be precise when measuring objects; any measuring error causes an error in
the computed range. Equally, incorrectly estimating the object size results in a proportional range error.
Here’s an example: A coyote is sunning himself in a snoweld beside a fencepost; having crossed the
fence earlier, you know that the post is four feet high, or 1.33 yards. e 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 magnication, it must
be set at the 12x 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 dierent distances.
e accompanying table lists one-mil widths from 100 to 600 yards, so you can calculate how many mils
to hold right or left when ring in a crosswind, or engaging a moving target.
