Chapter 9: Basic Shooting Skills
Rifle Shooting (continued)

Sighting-In Steps

Fire your rifle from a solid bench rest with the forestock resting on a pad or a sandbag. Don't rest the gun on its barrel—it will shoot higher than normal. Ideally, use an adjustable shooting tripod with sandbags. A spotting scope is also useful.

Sight-in instructions are printed on some targets available from retail outlets or manufacturers. The sighting-in process for most centerfire rifles begins at 25 yards, and then should be repeated at 100 yards. The basic steps involve firing at least three shots carefully and consistently at a target. If the bullets form a small group of holes on the target, but not where you were aiming, the sights will have to be adjusted.

When adjusting aperture or telescopic sights, the rear sights or dials are adjusted by a certain number of minutes-of-angle or "clicks" in a certain direction. Read the sight's instruction manual to see how much each click changes the sight at 100 yards.

The rear sight is moved in the same direction you want your shot to move on the target. Moving shots from side to side is "adjusting for windage." Moving shots up or down is "adjusting for elevation."

Specific instructions about trajectory and what fractions or inches you should be above the bull's-eye at 25, 50, or 100 yards are usually included on sight-in targets. You also might consult a ballistics chart or get help from an experienced shooter.
