TRADITIONAL BORE-SIGHTING (BOLT ACTIONS
Preliminary sighting-in can also accomplished by bore-sighting at the firing range using a target 20 to 50 yards away.
1. Position the firearm on the bench, using sandbags to steady the firearm .
2. Remove the bolt from the firearm .
3. Looking through the bore itself , move the firearm to center the bull’s-eye of the target inside the barrel , as shown in f1.
4. Hold the rifle steady .With the bull’s-eye centered when viewed through the bore , make windage and elevation adjustments to the scope until the very center of the reticle is aligned with the bull’s-eye of the target , as shown in f2.
TRADITIONAL BORE-SIGHTING (LEVER ACTIONS)
An inexpensive device with a small mirror , which inserts into the chamber or rests on the magazine follower to allow sighting down the barrel , is necessary for bore-sighting lever action rifles .Follow the instructions provided with this device when using it to bore-sight your lever action firearm.
THE FINAL STEP: THREE-SHOT GROUPS
Whichever bore-sighting method you’ve use , the next steps are the some on the firing range .To ensure reliable , always fire from a rested potion when performing these step . ( if you are using an adjustable objective or side focus model scope , perform any correction for parallax before continuing , as explained in “Understanding Parallax .” )
1. Fire a shot or two .
2. If you are several inches off center , make an appropriate amount of adjustment to move the reticle to the center of the target .
3. Carefully fire a three-shot group .
4. Use the center of that group as a reference point for the final adjustments to windage and elevation .
On the sample target the center of the group is two inches low and three inches right . Assuming you’re sighting-in at 100 yards , you should make a 2-MOA adjustment up , and a 3-MOA adjustment left. Your next three-shot group should be very close to the center of the target. To learn about making final adjustments, proceed to the upcoming section on windage and elevation adjustments.
