Bushnell 98-0243/04-03 Instruction Manual

To ensure years of dependable service,
we suggest you have your riflescope
professionally mounted.

An off-axis optical alignment between the
rifles bore and the riflescope may result
in scattered groups and poor optical
performance, as well as possible internal
damage to your riflescope.

Shimming may be required to properly
align your riflescope to the bore of the
rifle. This alignment of the riflescope
mount to the bore will reserve the rifle­scope’s internal adjustment for small,
fine corrections needed to sight-in.

A shim table is included to assist your
gunsmith in the proper mounting of your
riflescope to the suggested course
alignment.

SHIM GUIDE

*

ELEVATION and WINDAGE adjustment travel should
be reserved for fine correction. While normally not
required, major alignments should be made by shim­ming the mounts and/or bases. Over-adjustment of
Elevation and Windage controls may lead to internal
damage of your riflescope.

GUIDE DE CALAGE

Afin d'obtenir des années de service fiable,
nous conseillons de faire monter la lunette de
visée par un professionnel.

Un défaut d'alignement optique des axes de
perçage du canon du fusil et de la lunette de
visée peut entraîner des groupes dispersés,
une performance optique insatisfaisante, ainsi
que d'éventuels dommages internes dans la
lunette de visée.

Pour que la lunette soit correctement alignée
sur le perçage du canon du fusil, un calage
peut être nécessaire. Cet alignement de la
monture de la lunette sur le perçage du canon
permettra de réserver les réglages internes de
la lunette pour des corrections minimes néces-
saires au pointage.

Un tableau de calage est inclus pour aider
l'armurier à effectuer le montage correct de la
lunette de visée selon l'alignement de
trajectoire suggéré.
