Turret Adjustment M.O.A. (Minutes of Angle)
Adjustments are made in “Minutes of Angle” (MOA). This is a unit of measurement of a circle, and is 1.0472 at 100 yards. For all practical purposes it is called 1 inch at 100 yards. It is 2 inches at 200 yards, 5 inches at 500 yards, one half inch at 50 yards.

Scope adjustments are most often made in 1/4 inch increments at 100 yards. Each “click” of an elevation or windage turret will move your point of impact 1/4 inch at 100 yards. That same 1/4 inch click will move your point of impact 1/2 of an inch at 200 yards, or 1/8 inch at 50 yards. Some scopes have clicks that are 1/2 inch or even 1 inch. Some adjustment dials don’t have clicks at all, just a friction type adjustment that is infinitely adjustable.

If your bullet hole is four inches low at 100 yards and you have a scope with 1/4 minute clicks, you need to adjust your dial in the direction of the “up” arrow on your turret 16 clicks.

The turrets are housed in the center of your scope tube in a protrusion called the turret housing. The turrets are sometimes made to be turned with a coin, and sometimes they are finger adjustable. Target turrets are tall, and the clicks are easily seen and felt. Target turrets are most suited to use where they won’t get banged around or snagged on gear or brush. This is why hunting scopes don’t have them, and instead are much lower profile.

The turret caps are often sealed with an “O” ring, and help prevent moisture and debris entering the scope through its weakest parts.

Magnification
Riflescopes are specified by a set of numbers such as 6×42 or 3-9x40 etc. The first number(s) indicates the power of magnification or how much larger, or closer, the object will appear than when seen with normal vision. For example in a riflescope designation 6 x 42, for example, objects will appear 6 times larger, or closer, than when seen with the naked eye.

When considering magnification, more is not necessarily better. As magnification increases, brightness and clarity may diminish, depth of field can become shallower and the field of view is usually more restricted. More noticeable and disturbing at higher powers are fine hand tremors and the effects of atmospheric conditions, such as the distortion caused by heat waves.

If your observation is done primarily at close range, such as in woodland area, then a good 9 X riflescope might be the best choice. This range of magnification generally gives you a larger picture (wider field of view) which is especially important for viewing objects relatively close at hand. Also, riflescopes of this magnification usually deliver better performance under conditions of low available light, due either to the time of day, weather conditions, or shadows caused by dense vegetation or other structures. This same type of riflescope also works well for fast-moving action like sporting events, since the wide field of view allows the action to remain in the viewing area.

For long distance viewing or where greater detail is required, a higher magnification of 24 or 40 X should be considered. Great for target or long range shooting.

Remember: magnification should only be considered in relation to other factors such as aperture size, exit pupil, hand-held stability, atmospheric conditions, available light, optical design.

Eye Relief
Eye relief is the comfortable distance that a riflescope can be held from the eye and still allow the shooter to see the entire field of view. It is literally the distance of your shooting eye to the eyepiece. It will usually be stated as a range, since in a variable power scope the eye relief will vary with the power. Lateral adjustment can be made while mounting the scope to give the individual shooter the optimum eye relief.

On a rifle, the more generous the eye relief the better. This will allow you to acquire the target more quickly, which is a must for running shots. 3.5" (89mm) is a good number that will fit most hunters.

On large, powerful rifles, a greater eye relief is required, so when the rifle recoils, the scope doesn't come back and cause possible injury.

Field of View
When looking through a riflescope, the widest dimension of circular viewing area that you can see (the width of the horizon) is described as the field of view (F.O.V.). This is usually measured either in terms of linear metres at a 100m range or as an angle. As a general rule, the field of view will decrease as the magnification increases so a powerful 24 X riflescope will usually have a smaller field of view.

For observing at close quarters in deep woods, scanning the sky birds or for picking up fast moving objects such as rabbits, a wide field of view is desirable. If you have too large a field of view (over 150m for instance) the object you want to observe may become lost amid the confusion of its surroundings.

Exit Pupil
The small circle of light that appears in the eyepiece when you hold a scope at arms length is called an exit pupil. A formula for exit pupil is as follows: Divide the objective lens size in millimeters by the magnification.
Examples:
3-9X40 scope is set at 3X,
40 divided by 3 equals 13.3 mm which is large enough for almost all low light applications.

3-9X40 scope is set at 9X,
40 divided by 9 equals 4.4mm The difference in available light from the larger exit pupil is significant

Parallax
This is NOT a focus adjustment or a range finder. This adjustment allows your scope to adjust the optics, so that the crosshairs will be correctly positioned when shooting at different distances. This is accomplished by adjusting the front lens to remove the parallax, making sure the image focuses on the same plane as the crosshairs . . . . not in front or behind it.

Most scopes have a fixed parallax setting that is exactly correct for shooting at only "one" specific distance. If your scope has a parallax adjustment it can be perfectly adjusted for shooting at any distance, so that your crosshairs will appear to be rock solid, no matter where your eye is positioned. The crosshairs should appear stationary, as if they were painted on your target. This is very important when the "exact" position of your eye is not always concentric with your scope. The slightest variance can make a huge difference.
