BSA Optics CAT416X44SP - Manual (Page 5)

• The arrows on the dial show which direction they will move the bullet.
Turn according to the MOA scale on the dial.
The Catseye™ is 1/4 MOA, that means one click will move the bullet 1/4” at
100 yards. (Note, if you zero at a different yardage, say 50 yards, one click will
move the bullet only 1/8” at 50 yards.)
Once you have adjusted the windage and the elevation, you are now ready
for another 3 shot group. Repeat this process until you are satisfied with the
results.
Note: It is important to allow the barrel to cool down in between the three
shot groups as heating of the barrel can cause bullet flight to vary. It is also
recommended to swab the bore between shots with a dry patch to reduce
buildup. DO NOT use any cleaning fluid or oil on the swab as this can affect
bullet flight. If you are sighting in the firearm for hunting deer, you may want
to adjust the elevation an inch or two above bulls eye at 100 yards. This will
give your firearm extended range and still keep you in the kill zone at 100
yards and less. After zeroing, use the hex wrench provided to loosen the three
adjustment screws on both the windage and elevation knobs and reposition
them so the that the (“0”) lines up with the indicator line. Any further windage
and elevation adjustments can be made more precisely by calculating the
amount of clicks from the zero point.
5.) ILLUMINATED MODELS
Located at in the turret housing opposite the windage there is a rheostat
knob, which controls the degree of illumination. The lower the number the
dimmer the setting. The “0” position indicates the illumination is off.
Included with illuminated models is a 3v Lithium battery, type 2032.
TO INSTALL: Remove the battery cover and insert the battery positive side
up. Replace the cover. (NOTE: If the reticle dims or does not light at all,
replacing the batteries may be necessary).
