RIFLESCOPE

Bore Sighting
Initial bore sighting of the riflescope will save time and money at the
range. This can be done in a number of ways. A mechanical or laser
bore sighter can be used according to the manufacturer’s instructions.
On some rifles, bore sighting can be done by removing the bolt and
sighting through the barrel.
To visually bore sight a rifle:
• Place the rifle solidly on a rest and remove the bolt.
• Sight through the bore at a target approximately 100 yards away.
• Move the rifle and rest until the target is visually centered inside
the barrel.
• With the target centered in the bore, make windage and elevation
adjustments until the reticle crosshair is also centered over the target.

Final Range Sight-In
After the riflescope has been bore-sighted, final sight-in should be
done at the range using the exact ammunition expected to be used
while shooting. Sight in and zero the riflescope at the preferred
distance. 100 yards is the most common zero distance, although a 50
yard zero may be preferred for shorter range applications.
• Be sure the reticle is in focus (see Reticle Focus on page 4).
• Following all safe shooting practices, fire a three-shot group as
precisely as possible.
• Next, adjust the reticle to match the approximate center of the
shot group (see section on Windage and Elevation Adjustment on
page 5).
Note: If the rifle is very solidly mounted and cannot be moved,
simply look through the scope and adjust the reticle until it is
centered on the fired group.
• Carefully fire another three-shot group and see if the bullet
group is centered on the bulls eye.
This procedure can be repeated as many times as necessary to achieve
a perfect zero.
