Zeroing the Accu-Trac Remove the hex head screw and dial from the scope. Make zero adjustments as required using a screwdriver or coin inserted into the slot at the top of the elevation plunger.Accu-Trac is calibrated from 200 to 600 yards so you will need a 200 yard zero. If possible, zero on an actual 200 yard range. If a 200 yard range is not available, you can zero the scope high at 100 yards. The amount of this MRT is shown below:

Dial MRT

"A" +1.6"

"B" +2.0"

"C" +2.4"

"D" 0.0"

* "D" dial is calibrated from a 100 yard zero

Note: Accu-Trac elevation dials are different MOA value (Adjustment increment values) than the windage dials and the elevation dials on None Accu-Trac scopes. Elevation knob value per graduation for Accu-Trac scopes is 0.4" per click.

Calibrating the dial Once the scope has been zeroed, place the correct dial on the elevation turret and turn clockwise until it stops. (See the Accu-Trac Compatible ballistics chart shown below) The zero distance number should be aligned with the reference line on the outer tube. Tighten the hex head screw being careful not to change the elevation setting while doing so. Your Accu-Trac is now calibrated for the 200 yard zero and all other ranges.

Using Accu-Trac With the rifle at your shoulder in a normal shooting position, sight on the game, placing its body between the two "stadia" wires. Turn the power selector ring (zoom in or out)...

When the game fits between the stadia wires from shoulder to brisket, read the range as the last figure visible at the bottom of the scope.

With the proper dial for your bullet caliber and weight installed, turn the elevation dial to the range indicated (i.e. "5" for 500 yards). You have now compensated for bullet drop from zero at that range.

Aim right on target without holdover. Since you have already estimated range, you can increase or decrease the scope power as desired without affecting the trajectory or point of impact.

Avoid letting the sun shine directly into the objective lens. This lens can act as a "burning glass", causing deterioration of the Accu-Range scale inside of the scope.

Using Accu-Trac on various sized game Deer measuring approximately 18" from shoulder to brisket are perfect objects for using Accu-Trac. However, applying the factors listed below can also use other animals of larger or smaller size.

For example: The body of an elk measuring 24' from shoulder to brisket, indicates a distance of 300 yards. To compensate for the large body size, find the actual distance under the 300-yard column as 400-yards.

Coyote 9" shoulder to brisket 100 150 200 250 300

To install the proper dial for the bullet caliber and weight you will be using, simply find that bullet listing in the Accu-Trac Compatible Ballistics chart following. Remove the dial that comes with your scope and install the proper dial in its place.
