Adding a scope to your rifle will help you to fire consistent and accurate shots when hunting or during target practice. The scope's magnification ability, which will vary depending on the type of scope that you use, will also increase the range at which you can comfortably aim at a target. You will need to understand how to adjust your scope.
Secure the gun on the shooting table so that it is aimed at your target. Line up the open sights of the rifle, which you should be able to view beneath the scope mount, on your target.
Alternate your view between the open sights and the scope. By adjusting the alignment knobs on the scope, you will be able to bring the crosshairs of the scope in line with your view through the open sights.
Depending on the type of scope you are using, the alignment knobs will have an adjust value of ¼ or ½ inch at a given yardage, usually 50 or 100 yards. When you turn the knob there will be an audible "click." Each "click" corresponds to one unit of adjustment.
The initial adjustment will bring your scope close enough to being in line that you should at least hit the target with your first shot. You will need to fine-tune your scope by "clicking" in the scope with the adjustment knobs, either up and down or side to side. Some scopes can be adjusted by hand. Others will need to be adjusted using a small screwdriver or other tool.
On the first couple of shots you may be able to adjust the scope in large increments. As you narrow in on your target, you will soon be making finer, one-click adjustments. Keeping the rifle solidly braced ensures that variations from shot to shot are limited.
- You will have to make adjustments aiming based on the distance you are shooting if it is different from the distance you have sighted in to. It is good practice to know the manufacturer-specified trajectories of the ammunition you are using.
- It is best to sight your scope at a distance that is a common shooting range in your hunting area or on the target range. Always sight in your gun using the same ammunition you will be firing in the future. The ballistics of various bullets can result in different trajectories. If you will be switching the type of bullet you will be using, it is best to resight your scope. Scopes can be knocked out of alignment fairly easily. You should sight in your gun at regular intervals, and always before a new hunting season.
