Millet Sights TRS-2 - Manual (Page 6)

Mil-Dotbar™ reticle
Millett has developed the Mil-Dotbar™
reticle to assist the shooter in range-
finding and hold-over at longer
ranges. From the center of the Dot to
the Bar is one mil, which is 3.6
inches at 100 yards.
The TRS-1, and TRS-2 scopes Mil-
Dotbar is set for use at 10 X. On the
TRS-1 if you are not on 10 X power you
will have to adjust your measurement
using the Mil-Dotbar chart below.
At 500 yards it’s 18 inches and 36 inches
at 1000 yards. This measurement can be used
to hold over for bullet drop and for wind and
moving targets. The dot is .75 inches in diameter at 100 yards which is also useful as
a measuring device. The bar is .20 inches in thickness.
By learning to use the Mil-Dotbar reticle, you will be able to judge range and shoot more
accurately. See the range chart for more on the measurement of the system. See Chart 4 for
a simple method of use of the Mil-Dotbar reticle. A good reference is www.mil-dot.com.
Use of the TRS scopes and Mil-Dotbar at longer ranges
As the TRS scope does not have a turn counter on the elevation turret for keeping track
of number of turns adjusted, using the Mil-Dotbar reticle is more important. By sighting
in at a longer range and using the hold over measurements of the Mil-Dotbars, the lack
of a turn counter is less important.
If you sight your rifle in at 200 or 250 yards, it’s possible to get good accuracy out to
600 yards by using the Mil-Dotbars to hold over. For example; a 308 Win with a 168 gr
bullet sighted in at 200 Yards is 54 inches low at 500 yards, which is a 3 Mil-Dotbar
hold over for dead-on impact. At 600 the drop is 92 inches and 1 mil equals 21.6
inches, so 4 mils equals 86.4 inches. Therefore you need to come up 8 clicks as each
click equals .75 inches.
