BORE SIGHTER Model # 743333

Instruction

Manual

The Bushnell Professional Boresighter is an essential tool for quickly adjusting scope or

iron sights to align with the rie 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 ring to achieve pin-point zero at a given distance. Because of the many

variables involved in both ammunition and the rearm itself, nal “sighting in” must be done

by actual ring.

HOW TO BORE SIGHT A SCOPE-MOUNTED RIFLE OR HANDGUN

Scope/Rie Combination

Once you have secured the Boresighter, place the rie on a suitable support. Remove the

adjustment caps from your riescope. Then sight through the riescope and align the reticle

with the crosshairs of the graduated grid reticle in the Boresighter by using the riescope’s

elevation and windage adjustments. Once you have aligned the riescope reticle with the

graduated grid reticle in the Boresighter, you are ready for sighting-in on the range. If bore

sighting has been done properly, sighting-in should take a minimum of time and ammunition.

HOW TO INSERT THE EXPANDABLE ARBOR INTO THE GUN BARREL

Place the gun with mounted scope into a suitable support. Select the proper arbor and make

sure the expandable tips are completely closed by turning the arbor’s locking nut (Fig. 1/2: A)

counter-clockwise until the tips contract. Insert the small end of the arbor into the Boresighter

mount with the at area down, so that the end of the clamp screw will bear against (Fig. 1/2: B)

the at surface. Turn the screw clockwise until it is ngertight. Now, with the Boresighter in an

upright position, insert the arbor into the barrel and push it forward carefully until the muzzle

rests against the tapered section of the arbor ). With the arbor locking nut loosened, (Fig. 2)

and while looking through the scope, swing the Boresighter to align vertical grid lines with

the scope reticle. Turn the arbor locking nut clockwise until the arbor holds rmly to the bore;

the expandable tips prevent the Boresighter from turning of its own weight.

NOTE: To remove the arbor from the barrel, simply loosen the arbor locking nut (Fig 1: A),

push inward to retract the tips, and pull the unit from the barrel.

After “sighting-in”, don’t forget to reinstall the Boresighter and record the reticle position.

Scope/Handgun Combination

Once you have secured the Boresighter to the barrel, place the handgun on a suitable

support. Remove the adjustment caps from the scope. Sight through the scope and align

the crosshairs with the crosshairs in the Boresighter using the scope’s elevation and windage

adjustments. Once you have aligned the scope crosshairs with those of the Boresighter, your

handgun is ready for sighting-in on the range.

How to Bore Sight a Rie or Handgun with Iron Sights

Once you have secured the Boresighter to the barrel, place the handgun or rie on a suitable

support. Viewing through the rear sight, adjust the sights to align with the crosshairs on

the graduated grid reticle in the Boresighter. When you have completed bore sighting, the

handgun or rie is ready for sighting-in on the range.

After “sighting in” by ring, 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 eld. Be sure to note the ammunition that was used.

On the hunt, the Boresighter is an invaluable aid for making sure that your rie 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.

How to Make Corrections for Bullet Drop

Using the scope adjustments, you can

make correction for bullet drop at a

specic distance provided the trajectory of

the specic load is known. Each graduation

on the Boresighter grid is equivalent to 4

inches at 100 yards. When the scope reticle

is below the grid center, the gun will shoot

high.
