When it comes to rifle scopes, the numbers on the scope can be confusing. Many people don’t know what the numbers mean and how they affect the scope’s performance. The most common numbers on a rifle scope are 3 9x40. So, what do these numbers mean? The first number, 3, is the magnification power of the scope. This means that the image you see through the scope will be three times larger than it would be without the scope. The second number, 9, is the diameter of the objective lens in millimeters.

The objective lens is the lens at the front of the scope that gathers light and projects the image onto the reticle. The last number, 40, is the size of the exit pupil in millimeters. The exit pupil is the light that is projected through the eyepiece of the scope. The combination of these three numbers is important for determining the performance of the scope. The larger the magnification power, the more detail you will be able to see in the image. The larger the objective lens, the more light will be gathered and the brighter the image will be. The larger the exit pupil, the more light will be projected through the eyepiece and the brighter the image will be.

When choosing a rifle scope, it is important to consider the numbers on the scope. The 3 9x40 combination is a good starting point for most shooters. Rifle scopes are an essential tool for any hunter or shooter. They allow you to accurately aim and hit your target from a distance. But what do the numbers on a rifle scope mean? The numbers on a rifle scope refer to the magnification power of the scope.

The first number is the magnification power, and the second number is the diameter of the objective lens. For example, a 3-9x40 scope has a magnification power of 3-9x, meaning it can magnify the image 3 to 9 times. The 40 refers to the diameter of the objective lens, which is 40mm. The magnification power of a rifle scope is important because it determines how far away you can accurately shoot. Generally speaking, the higher the magnification power, the farther away you can shoot. A 3-9x40 scope is good for shooting targets up to 300 yards away.

However, if you need to shoot targets farther away, you may need a scope with a higher magnification power. In addition to the magnification power, the size of the objective lens is also important. The larger the objective lens, the more light it can gather, which can help you see your target more clearly. A 40mm objective lens is good for shooting targets up to 300 yards away, but if you need to shoot targets farther away, you may need a larger objective lens.

When choosing a rifle scope, it is important to Rifle scopes are an essential tool for any shooter, allowing them to accurately and precisely aim their shots. But what do the numbers on a rifle scope mean? Understanding the numbers on a rifle scope can help you make the right choice for your shooting needs. The numbers on a rifle scope refer to the magnification, the diameter of the objective lens, and the size of the exit pupil. The first number is the magnification, which is the amount of times the image is magnified.

For example, a 4x12x40 scope means that the image is magnified 4 times. The second number is the diameter of the objective lens, which is the lens at the end of the scope that gathers light. In this example, the objective lens is 12mm in diameter. The third number is the size of the exit pupil, which is the size of the beam of light that exits the scope. In this example, the exit pupil is 40mm.

The magnification of a rifle scope is important for determining the range of your shots. Higher magnification scopes allow you to shoot at longer distances, while lower magnification scopes are better for close range shooting. The diameter of the objective lens is important for gathering light, which is important for shooting in low light conditions. The size of the exit pupil is important for determining how much light is available to the shooter. A larger exit pupil means more light is available, which is important for shooting in low light
