BORE SIGHTING
Bore sighting is a preliminary procedure to achieve proper alignment of the scope with the rifle bore. It is best done using a
Bushnell
®
Bore Sighter. If a bore sighter is not available, it can be done as follows: Remove the bolt and sight through the gun
barrel at a 100 yard target. Then sight through the scope and bring the crosshairs to the same point on the target. Certain
mounts have integral windage adjustments and, when bore sighting, these should be used instead of the scope’s internal
adjustments. If major elevation adjustments are needed, they should be accomplished by shimming the mount base.
ZEROING
Final sighting-in of your rifle should be done with live ammunition, based on your expected shooting distance. If most of your
shots will be at short range, zero-in at 100 yards. But, for long-range shooting at big game, most experienced shooters zero-in
about three inches high at 100 yards. Three-shot groups are useful for averaging the point of impact.
ELEVATION AND WINDAGE ADJUSTMENT
Your Bushnell

Trophy

Xtreme scope features finger-adjustable, audible-click elevation and windage adjustments.
1. Remove the covers from the Elevation and Windage Adjustments.
2. Grasp the Adjustment Dial and turn it in the appropriate “UP” (and/or “R”) direction indicated by the arrows. Each “click” or
increment on the Adjustment Scale Ring will change the bullet impact by ¼” Minute of Angle. See scope adjustment dial
for the click adjustment value on your scope. ¼ MOA corresponds to ¼ inch at 100 yards, ½ inch at 200 yards, ¾ inch at
300 yards and so on.
RESETTING THE ADJUSTMENT SCALE RING
This step is not necessary, but, for future reference, you may want to realign the zero marks on the Adjustment Scale Rings
with the index dots.
1. Using a jeweler’s screwdriver, loosen the two Phillips screws on the Adjustment Bar about 1/2 turn. Take care not to
