2. With scope mounted set zoom to mid power and rest the rie on a
steady support.
3. Look through the bore from the breech at a target 50 yards away.
Move to butt stock so that the target is in the center of the bore.
4. Without moving the rie, loosen the lockable bell of the scope at
the base of the turret by turning it counter clockwise with ngers
(see image below).
5. Turn the windage and elevation adjustment dials in the direction you
wish the bullet’s point-of-impact to change (up/down, left/right).
6. Tighten the lockable bell of the scope at the base of the turret by
turning it clockwise.
Boresighting
Bore sighting your riescope with you rie will allow you to quickly and
more accurately “zero in” or “sight in” your riescope to the correct
shooting distance. You will always need to shoot a test group of shots
after you bore sight your ries to you rie. Bore sighting your riescope
will reduce wasting ammunition when targeting in your rie during
test shooting.
Example: You have a newly mounted zoom power riescope on a
rie and aim at a target 100 yards away. You aim for the center of the
target with the scope and re for the rst time, but you see no impact
on the target in the view of the scope. If you were not able to see
where the bullet actually landed then you would need to guess how
you need to adjust the scopes windage and elevation on the next shot.
You would need to continue shooting multiple test shots and adjusting
the scope until the actual impact of the bullet comes into view of the
scope. This will waste time and ammunition.
Why does this happen? A newly mounted riescope’s actual zero
point on a rie is unknown due to many variables; type of scope base,
height of mounting rings, type of rile, type of ammunition etc.
Zeroing
Set scope zoom to the max power, and adjust the windage and
elevation knobs as needed to correct the aim.
After zeroing in your scope, you can follow pre-zeroing procedure to
scale back to zero.
Each click adjustment of the windage and elevation changes/moves
the bullet strikes by the amount in chart below.
1/4”
WINDAGE / ELEVATION (inches per click or movement)
50yds
100yds 200yds 300yds
1/8 inch 1/4 inch 1/2 inch 3/4 inch
NOTE: Climatic conditions such as rain and wind as well as altitude
can affect the trajectory and you might nd it useful note some sight
deviations in the settings from one shooting session to the next.
Re-Zeroing
Re-zeroing scale back to zero is optional and should only be done
after zeroing in your scope.
WARNING: Turning the hex screw too tight or too loose can cause
damage to the scope.
1. Loosen the lockable bell at the base of the turret by turning
it counter-clockwise.
2. Loosen hexagon screw by turning counter clockwise until the screw
hits the stopper screw inside. About 1-1½ turn of the allen wrench.
Note: The hexagon screw CANNOT be totally removed.
3. Pull the turret cap gently up to disconnect it from the drum inside.
4. Turn the cap to reset the scale to zero.
5. Hold the cap and turn hexagon screw clockwise to lock the cap
1-1½ turn of the allen wrench.
6. Your scale is now re-zeroed.
