Most owners of rifled weapons try to equip it with a telescope sight to be able to effectively hunt furry or hoofed game. Pleasure is not cheap, so that money is not wasted, you need to understand how to make a choice. And the result of the shooting will depend on the correct decision.

The first thing buyers see is the multiplicity. Simply speaking, this characteristic shows the ability of the sight to zoom in (bring closer) the object under consideration. The ratio determines the distance at which the reticle will be optimally used. Certainly, figures show not the maximum distance to the target, but the degree of magnification of the image of the object in comparison with how the human eye perceives it at this or that distance.
In order to select the correct multiplicity, it is necessary to have an accurate idea of the distances at which the shooting will be conducted. And to make it easier to orientate, there are special tables, which roughly compare the estimated range and multiplicity.
By multiplicity all sights are conditionally divided into three groups:
- Small multiplicity (1-6);
- The average multiplicity (7-9);
- High multiplicity (from 10).
The sight with a multiplicity of 1-6 is enough for encampment hunting. This will allow you to shoot even with a tip, aiming with two open eyes like with a colimator sight. On hunts with the approach it is advisable to use the sights of medium magnification. Well, high-frequency sights require bipods, focus when firing. In addition, the sights with the multiplicity of more than 15 are already installed on the army weapon samples when used in military affairs.
Also when selecting the multiplicity, remember that the higher the approach, the narrower the field of view. That’s why small and medium multiples are used for paddock hunting and when firing from the approach.
The sights are divided into two more groups:
- With constant multiplicity (for example, 6×50 or 4×32);
- With variable multiplicity (e.g. 1-6×50).
In the first case, the reticle may be slightly restricted due to more or less fixed range of application. However, its reliability is significantly enhanced by the relative simplicity of the device.
Variable multiples, of course, expands the scope of the arrow. Allows the same sight to be used on different hunts, both in forest and open space. Of course, such sights are much more expensive.
Input lens diameter
There is no doubt that the second digit in this indicator is striking when choosing the reticle’s multiplicity. For example, 6×50. It indicates the diameter of the input (front) lens in the lens. This value is expressed in millimeters and affects the amount of light that is allowed to pass through the lens. The larger the diameter of the lens (lens), the more light it transmits, which means that the picture will be clearer and the target will be better viewed.
It is worth remembering here that sights with large lenses require high mounts on the gun or the use of special adapters that connect the mounts to the sights itself.
Output pupil diameter
This characteristic also affects how well the target is seen, especially in low light conditions. It is calculated by dividing the lens diameter by magnification and is expressed in millimeters. For example, for the 8×32 sight you need 32 divided by 8. It’ll be 4 mm. The optimum value is 5 mm.
The sighting grid is a scale that is applied to one of the lenses. That’s what the shooter sees when he’s aiming through the optics. There are several types of nets designed for different firing conditions. In addition, there are also branded nets, which are a kind of business card of any brand.
The Saami simple grid – a classic cross or cross – allows you to aim at stationary targets at short distances. More complex mesh variants have additional divisions and scales, with the help of which the shooter can determine the distance to the target, its size. Such grids are used mainly at distances from 500 meters.
Also, when selecting a grid, it is necessary to take into account the conditions of firing, weapons. A well-trained specialist can help you make the right choice. Very good if the grid is backlit.
Parallax is an effect in which the target and the reticle move relative to each other if the shooter changes his eye position relative to the optical axis of the reticle. This effect can be removed by adjustment, but not on all sights. Some of them have a fixed setting at a certain distance. Others are designed with an adjustment device. In layman’s terms, it’s a “wheel on the side of the scope body. It can also be a tagged ring located on the lens.
Here it is necessary to orient, first of all, on the brackets with which the weapon is equipped.
The most common are swallowtails and Weaver or Picatini bars. It is not always possible that the scope mounts may coincide completely with the gun mounts. For these cases there are adapters – adapters. You’ll have to buy them separately.
These are the main features of the sights, which should be paid attention to in the first place. It only remains to add that a good, high-quality device will always be hermetic, filled with inert gas (most often it is nitrogen).
As for the cabinet materials, it is best if it is steel or anodized aluminium. Such sights withstand the recoil well even on large calibers with a powerful cartridge.
A good telescopic sight, if not predict the success of hunting, is able to significantly affect it in any case. But besides the quality of the device itself there is another important factor – the right choice. Here are two good scopes comparison – https://tacticsfaq.com/vortex-viper-vs-venom/.
When buying a sight it is important to ask yourself a question: for what purposes you choose it, what kind of hunting (or shooting) and from what weapons are you going to do? Yes, there are universal sights, suitable for different tasks, but they also have their limitations. Here we will consider the main characteristics of telescopic sights and their influence on the success of shooting under different conditions.
