Bushnell PROFESSIONAL BORE SIGHTER 74-3333 User Manual

The Bushnell Professional Boresighter is an essential tool for quickly adjusting scope
or iron sights to align with the rifle or handgun barrel. Correct use of your Boresighter
will put sighting-in test shots “on the paper”, requiring only minor expenditure of time
and ammunition by test firing to achieve pin-point zero at a given distance. Because of
the many variables involved in both ammunition and the firearm itself, final “sighting
in” must be done by actual firing.
After “sighting in” by firing, reinstall the Boresighter in the muzzle of your gun and
note the position of your scope reticle on the grid of the Boresighter. Make a record
of this position for later use in checking the sighting in the field. Be sure to note the
ammunition that was used.
On the hunt, the Boresighter is an invaluable aid for making sure that your rifle remains
accurately sighted when test shots would frighten the game for miles around! In the
shop it is ideal for checking stock bedding for sensitivity to barrel pressure.
