BORE SIGHTING METHOD
1. Place a target at 25 to 50 yards.
2. Remove the bolt from the rifle.
3. Place the rifle on sandbags or a shooting rest.
4. Set the scope to its lowest magnification.
5. Peer through the bore from the receiver and adjust the position
of the rifle to center the target bull’s eye in the bore (Fig. A).
6. Without moving the rifle, look into the scope and note the
position of the reticle on the target. On models with capped
elevations and windage adjustments, remove the caps. Adjust
the windage and elevation adjustments to center the reticle on
the bull’s eye (Fig. B).
FINAL SIGHTING-IN
WARNING: SINCE THIS PROCEDURE INVOLVES LIVE FIRE, IT SHOULD BE DONE AT AN APPROVED RANGE
OR OTHER SAFE AREA. CHECK BORE FOR OBSTRUCTIONS. AN OBSTRUCTED BORE MAY CAUSE INJURY TO
YOU AND OTHERS NEARBY. EYE AND EAR PROTECTION IS RECOMMENDED.
1. From a steady rest position, fire two or three rounds at a 100-yard target. Note the impact of the bullet on the target
and adjust the windage and elevation dials as needed.
2. To move the bullet impact, turn the windage and/or elevation adjustments in the direction on the dials that corresponds
to where the impact point falls on the target (for example, if test shots are hitting low, adjust elevation “down”). The
adjustments on your riflescope model are marked in MOA (minutes of arc), and the point of impact at 100 yards will
change by 1/4 MOA for each click of the windage or elevation adjustment. One full revolution of the adjustment=12
MOA.
3. When the impact on the 100-yard target is satisfactory, switch to a target set at the desired distance for final zeroing.
Set the magnification to the desired power on variable power models.
THE DROP ZONE 22LR RETICLE (Model # RP3103BS4 only)
The Prime scope model with the DROP ZONE-22LR Reticle is designed to be sighted-
in at 50 yds, with aiming points every 25 yds, out to 125 yds. This reticle is calibrated
for use with .22 Long Rifle high velocity ammunition. The scope must also be set to
the highest magnification for the reticle’s ballistic feature to function properly. In the
case of the 3.5-10x36mm model featuring this reticle, the power change ring must be
set at 10x for the ballistic function to work correctly
How To Use the DZ 22LR Reticle:
1. Sight in at 50 yds on any magnification setting.
2. Determine distance to target. For the best accuracy in determining distance,
utilize a Bushnell Laser Rangefinder (Prime™ or Nitro™).
3. Set the scope’s magnification to 10x (10 power).
4. Place the appropriate aiming point on the desired target. If the target was
determined to be at 115 yds, hold directly between the 100 yd aiming point and
the 125 yd aiming point.
ALTITUDE AND TEMPERATURE
Ballistic charts published by ammunition manufacturers are based upon standard sea level conditions. When sighting in,
it is well to keep in mind that altitude and temperature affect trajectory. It is best to sight-in under the same conditions in
which you will be hunting.
DO YOU NEED TO SEND YOUR SCOPE TO US?
Before returning your scope for service, you should check the following points to make sure the problem is with the scope:
• Check the mounting system and rings for looseness or misalignment.
• Check to be sure the barrel and action are properly bedded and all receiver screws are tight.
• Check to be sure the mounting system allows sufficient clearance between the objective bell and the barrel.
• Check to be sure you are using the same type and weight ammunition that you used for sighting-in.
