Bore sighting is a preliminary procedure and usually takes place within a close range of somewhere between 25 to 50 yards using a large paper target. While the bolt action and single-shot guns can be bore-sighted in an old-fashioned way by looking through the barrel, semiautomatics, pumps, and lever-action rifles can be sighted only with the help of a device called laser bore sighter.
The bore sighter can be inserted in the muzzle, or the chamber of your rifle, and its role is used to line up the barrel with your optics. Make sure you get a bore sighter that is suitable to the type of weapon you are using, as they range in size. One bore sighter that I use often is the SiteLite Ultra pictured below , which fits all calibers from.

After you fire the first group, you will need a little mathematics to work out what changes you need to make. Your shots might not have hit the center, so you should measure in inches how far off your group Point of Impact POI was from the center and adjust your scope until the crosshairs of the reticle are right in the center of the three-shot group.
In the image below, you can see how the adjustments work to bring your tight grouping to the center of the target. Since you have taken both the vertical and horizontal distance of the center into account, you will recalculate inches in MOA Minute of Angle — as seen below and convert it into the appropriate amount of clicks with turrets on your riflescope. The MOA is simply a unit of measurement for an angle, except it uses time as a measurement.
One MOA is equal to one inch per yards. The best way to work out your MOA is to measure your grouping. If you are shooting at a target that is 50 yards away, and you have shot 3 inches to the left of that target, then remembering that 1 MOA is 1 inch per yards, your MOA taking a look at the diagram below is 6 MOA.
For example, adjusting the scope for windage or elevation for 1 inch would take 4 clicks of rotation. However, if you are following a trend toward scopes of higher power and hunting with longer distances than yards, you will need some of the scopes for yards. Get your eyepiece situated in such a way that you see a clear, distinct image.

There is no time to waste trying to find your target in your scope. What makes a scope work is the amount of light that passes through its lenses.
So, what happens in a low-light situation? Overcast days, dawn, dusk and thick woods will all affect the workings of the scope.
