U SING A BORE - SIGHTING COLLIMATOR
To save time and ammunition, start out in your shop or gun room with a
bore-sighting collimator (a spud and an optical assembly) to “get on the
paper.” Remember that adjustments made during bore-sighting will appear
to move in the opposite direction than that indicated by the adjustment dial.
1.
Assemble the collimator with the correct spud and insert it into the barrel.
2.
Look through the scope. Note that the collimator displays a crosshair that
is at 45º to the scope’s reticle. The center of the scope reticle is normally
some distance away from the center of the
boresight reticle. This shows the scope’s
line of sight relative to the axis of the bore.
3.
For purposes of demonstration, Figure A
depicts a scope that is low and to the left.
Begin with the windage adjustment.
