Troubleshooting
Many times, problems thought to be with the scope are actually
mount problems. Be sure the mounts are tight to the rifle and
the scope is secured so it doesn’t twist or move in the rings.
An insufficient windage or elevation adjustment range may
indicate problems with the base mount, base mount holes drilled
in the rifle’s receiver, or barrel/receiver alignment.
Check for Correct Base and Ring Alignment
1. Re-center the scope reticle (see Centering of the Reticle).
2. Attach bore sighter, or remove bolt and visually boresight rifle.
3. Look through the scope.
If the reticle appears way off center
on the boresighter image or when compared to the visually
centered target when looking through rifle’s bore, there may
be a problem with the bases or rings being used. Confirm
that correct base and rings are being used—and in the proper
orientation.
There are many issues that can cause poor bullet grouping.
Grouping Problems
• Maintain a good shooting technique and use a solid rest.
• Check that all screws on rifle’s action are properly tightened.
• Be sure rifle barrel and action are clean and free of excessive
oil or copper fouling.
• Check that rings are correctly torqued per the manufacturer’s
instructions.
• Some rifles and ammunition don’t work well together—try
different ammunition and see if accuracy improves.
