| The
following information is to assist you in properly zeroing your
scope. Normally, not more than six to eight inches of adjustment
are required for zeroing. In extreme cases, ten to twelve inches
are needed. We suggest you carefully check your mounting system
first. Your scope is optically centered from the factory, which
means the erector system in your scope sits right in the middle
of the scope's tube. Any adjustments made using the W/E dials
will move the erector system from the center. Please make sure
that you can zero the Point of Impact (bullet impact point)
and Point of Aim (crosshair point) without using excessive amount
of W/E adjustment. |

FOR
THOSE WHO DO NOT HAVE A
BORE-SIGHTER
|
| Mount
your scope on your rifle and tighten all screws. Set the target
at 25 yards. From bench rest, aim at the center of your target
and shoot 2 or 3 rounds. Examine your target, check how far
your Point of Impact (POI) is from your Point of Aim (POA).
If the bullet hits were more than 3 inches (12 inches/100 yards)
apart from where you aimed at, you have problem(s) with your
mounting system. Do not use W/E adjustment screw. Adjust the
mounting system first. |

FOR THOSE WHO ARE USING A BORE-SIGHTER
|
With
the top portion of your mounting rings open, put your riflescope
on your rings, determine how far the center of your crosshairs
is from the center of your bore-sighter grid. If they are more
than 3 squares (12 inches/100 yards) apart from each other,
you have problem(s) with your mounting system. Do not use W/E
adjustment screw. Adjust the mounting system first.
NOTE: Never force the W/E screws past their natural stop. Internal
damage can result rendering the scope inoperative. The most
common occurrence with "over-adjusting" includes: power change
system jamming, broken inner lenses, poor image quality, insufficient
grouping of shots, and limited or irregular movement of POI
alignment. |

AFTER YOU HAVE BORE SIGHTED AND IT IS
CLOSE
|
Locate a safe place to test fire and fine tune your firearm,
preferable a firing range. The next step is to find a stable
surface to fire from. If you cannot hold the firearm still,
it will not zero in correctly. A couple of small sand bags
will come in handy for stabilizing the firearm. A dry patch
should be run through the bore to remove any oil. With a
target set up at 100 yards you are now ready to test fire.
Holding the crosshairs steady on the target, squeeze off
a round. Repeat this two more times to get a three shot
group. Retrieve your target and triangulate the shots to
get an average point of impact. Measure from that POI to
the bulls eye where you aimed. This measurement can now
be adjusted out with adjusting screws located under the
top and side (screw off caps) located in the center of the
scope. The arrows on the dial show which direction they
will move the bullet. Turn the adjusting screws according
to the MOA scale on the dial. If they say 1/4 MOA, that's
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 (side screw) and the
elevation (top screw), you are now ready for another 3 shot
group. Repeat this process until you are satisfied with
the results. 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 bullseye at 100 yards. This
will give your firearm extended range and still keep you
in the kill zone at 100 yards and less. Sighting in should
be done on a windless day or a least on a day when the wind
is 5mph or less. When it is time to go shooting or hunting
later, make sure to run a dry patch through the bore to
remove the protecting oil that was used after the last cleaning.
