range SighT-in and rZr Zero STop SeT
Once the riflescope has been boresighted, final sight-in and RZR
Zero Stop set should be done at the range shooting the same
ammunition expected to be used in the field. 100 yards is the most
common zero distance, although a 200 yard zero may be preferred
for long distance applications. As previously noted in the section on
Boresighting, the outer elevation turret cap should be removed and
zero stop lock screws on inner turret should be loose.
1. Be sure to follow all safe shooting practices.
2. Before shooting, be sure the reticle and side focus are properly
set (see Reticle Focus Adjustment pg. 6, Image Focus pg. 8).
3. At your preferred zero distance, fire a three-shot group as
precisely as possible.
4. Next, adjust the reticle to match the approximate center of the
shot group (see section on Windage and Elevation Adjustment). If
the rifle is very solidly mounted and has not shifted you can simply
look through the scope and adjust the reticle until it is centered on
the fired group.
5. Carefully fire another three-shot group and see if the bullet group
is centered on the bullseye. Repeat process until group is centered
in desired spot.
6. Gradually tighten the three inner
turret zero stop lock screws in an
even pattern until firmly tight. If
using torque wrench, tighten screws
to approximately 8 in/lbs.
7. Replace elevation turret outer cap, being sure to align “0” mark
on cap with the zero reference line on scope body. Push the cap
straight down and avoid rotating while doing this. Be sure the cap is
fully down.
8. Gradually tighten the three outer elevation cap retaining screws
in an even pattern until firmly tight. If using torque wrench, tighten
screws to approximately 8 in/lbs.
9. Check to be sure the zero stop
is correctly set – elevation turret
should not be able to rotate in
clockwise direction.
Note: After setting, if zero stop does rotate clockwise or if you wish
to re-zero a different load, repeat complete boresighting and range
sight-in procedures. It is very important to always begin any sight-in
adjustments by turning elevation turret clockwise until fully stopped.
