TURRETS PRE-ZEROING
Before mounting the scope remove the windage and
elevation caps (where fitted) to expose the adjusters.
Typical examples of turrets are shown below:
1. Low profile resettable.
2. Finger Resettable
3. Posi-grip resettable style. 4. Low profile resettable
5. Locking and resettable.
6. Turret reset to zero
Turret Adjustment:
Each click of adjustment is measured in minutes of
angle on the target. One click of movement equates
to 1/4” of movement on a target set at 100 yds
distance. Therefore at different ranges, each click
of adjustment changes:
Example: One click at:-
-50 yds -100 yds -200 yds -300 yds
1/8” 1/4” 1/2” 3/4”
Pre-zero sighting can be done either visually or with a
bore sighting collimator. Bore sighting collimators such
as the “Hawke Shot Saver” are the best way to pre-zero.
If a Bore sighting collimator is not available, it is
recommended to pre-zero visually.
To bore sight visually:
• With the firearm in a steady rest position open the
action of the firearm and look along the bore to a
predetermined target (at approximately 50 yards
distance).
• Scopes fitted with an adjustable objective or side
focus should be adjusted to the 50 yds position.
Set a variable power scope to mid-power.
• Remove the caps from the windage and elevation
turrets. Adjust the windage and elevation adjusters
to position the reticle on the center of the target.
• For windage adjustment, turn the windage
adjustment turret clockwise to move the point of
impact left and counter clockwise to move the point
of impact right. In the same manner, adjust the
elevation by turning the elevation adjustment
clockwise to lower the point of impact and counter
clockwise to raise the point of impact.
NOTE: When using windage-adjustable rings,
make major windage correction with them. In certain
shooting situations such as close range air gunning
when specialised elevation adjustable rings are
not available, the rings may have to be shimmed.
Only final precision adjustment should be made with
the scope’s adjustment turrets.
