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.

SIGHTING IN RIFLE AT THE RANGE

-Remove the elevation cap. If the standard elevation turret is not installed, remove the BDC turret and install it. This is done by using a coin to unscrew the retaining screw in the center of the turret. Grasp knurl at top of the Turret and lift upward, disengaging turret from the elevation adjustment pin. Reverse to install a new turret.

-Sight-in the rifle, firing a group of at least three shots at 100 yard target. Note the relationship of the center of group to the center or the target. Rotate the turret the required number of clicks to make the necessary point of impact move. Follow with the windage adjustment to bring shots to center of target. Fire another group to see if proper adjustment has been made. Repeat as necessary until center of group is in center of target.

-Once the rifle is sighted-in at 100 yds, you may install the proper BDC Turret for your caliber and bullet weight (see “SELECT PROPER TURRET” below).

(NOTE: When the selected BDC turret is installed, the elevation cap cannot be used. If the standard elevation turret is installed, the cap can be threaded onto the scope).
