Never use the scope as a substitute for binoculars. Never watch another person through the scope. As always, the Golden Rule applies. 10 11 11 How to Sight-In USING A BORE-SIGHTING COLLIMATOR To save time and ammunition, start out in your shop or gun room with a bore-sighting collimator. Follow the directions included with the collimator for specific instructions on its proper use. Remember, when possible, it is better to make the initial windage adjustments to the mount base before using the scope’s windage adjustment. NOTE: Bore-sighting alone is not sufficient to sight-in a scope. You must make final adjustments by shooting the firearm using the same ammunition you use in the field. USING THE LEUPOLD ZERO POINT ILLUMINATED MAGNETIC BORESIGHTER This tool fits any rifle, shotgun, or pistol, and helps you get “on the paper” fast, without barrel spuds. It works with any optical sight, and can even be used to recheck your zero, without firing a shot. See your Leupold Golden Ring Dealer or visit for more information. 12 TRADITIONAL BORE-SIGHTING (BOLT ACTIONS) Preliminary sighting-in can also be accomplished by bore-sighting at the firing range using a target from 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 Figure A. 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 Figure B. Target as seen through the bore.

To ensure reliable results, always fire from a rested position when performing these steps. (If you are using an adjustable objective or side focus model scope, perform any correction for parallax before continuing, as explained in “Understanding Parallax” on pages 24-27.) 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. 13 THE FINAL STEP: THREE-SHOT GROUPS Whichever bore-sighting method you’ve used, the next steps are the same on the firing range.

Use the center of that group as a reference point for the final adjustments to windage and elevation. 14 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. 14 On the sample target, the center of the group is two inches low and three inches right.

Making Precise Windage And Elevation Adjustments 15 The style of elevation and windage adjustments on Leupold riflescopes varies with specific models. Each, however, is clearly marked in easy to read increments. If, for example, there are four hash marks from zero to (and including) the number one on an adjustment knob, then the value of each increment...
