Have you ever get stuck that buying a long-range scope? The technical specifications, the terminologies, and other acronyms can become a tricky part for a great hunting game.

However, you do not have to worry about it anymore because all of them require a bit of a deep understanding to select an excellent long-range scope.

Long range hunting

If you are in this stream and try to hook a new optic for your firearm, I am here to support you through my post.

Check the quality of the optic

To adjudicate the quality of optic used for a scope lens, the best point would be checking it straightly.

If you are not sure the designs of rifle optics, it would be great to find out the reputable brand. Seek to enterprises which have premium quality lenses. If you scrutinize a scope in individual, it would be cooler!

Know what “exit pupil” is mean

Frankly speaking, a low-light performance of an optic depends on several factors. However, the exit pupil plays a significant role in this performance.

It is found by classifying the objective lens diameter from the magnification. You even could recognize the trade-offs in capability.

For instance, an 8×32 binocular chassis has the 4-millimeter exit pupil.

Please keep in mind that you should apply the exit pupil above 4 millimeters in the low-light performance.

This offers your eye a correct, suitable amount of light when it is modified in darker conditions. In the bright conditions, your eye’s pupil narrows. In other words, you should take a smaller exit pupil and it is definitely ideal most of the time.

Modify your diopter

In general, long-range scopes are equipped with a diopter adjustment to support focus. This is because the diopter is used to emphasize the reticle at the back of the eyeball. Diopter adjustments are used for your eye and left alone.

To make your rifle scope diopter properly, seek the rifle scope at a simple background (it is probably closer than 20 feet). Modify the diopter until the reticle is definitely clear. Please bear in mind that when the diopter is put, you should no longer adjust it!

What happens when you do not adjust the diopter on your long-range scope? You probably have a fuzzy reticle and it does not offer the right aim.

It is popular for people to peep that when using binoculars for a long period of time, they get headaches. It will not occur in the right diopter!

Position the reticle

The reticle is the first or the second focal plane. Sometimes, it is inbuilt at the back or in front of the zooming process.

In general, reticles in the first focal plane are more correct but it often changes with the zoom levels.

The second focal plane is more stable, but it will need more indemnification when shooting. This will create a big difference in the long-range scopes.

Determine how much magnification you will need

Scope often comes with two numbers like 13-9×40 and a wide range of magnifications. It relies on your range as well. The number in the left show how much big the target will see at naked eyes. The 3x will create the target occur three times as large in the optic.

For carbines, it is recommended that a reflex sight can work well. It is often solid enough for most promiscuous hunters or standard target shooters.

There is no actual benefit to settling for higher magnification. The 20-time zooming can use for hunting whitetail deer which often causes missed shots and wasted ammo as well.

Check your frequent environmental conditions and how strong the scope is

A good long-range scope often has fog-proof and waterproof factors. If not, your hunting game does not have a good consequence at all.

This is a basic requirement! However, not all of the scopes are made to keep up in additional conditions like humidity, moisture, and heats as well.

In case you have to hunt in various conditions or live in harsh environments, pay more money for a scope with these extra scenarios.

Understand additional features in a long-range scope

Along with the reticle and diopter, you should also recognize other features.

  •       MOA: Usually, 1 MOA will be 1 inch (2.5cm) when shooting at 100 yards. Therefore, if you cannot catch 1 inch, you will need to adjust with a click. They are the most popular for various shooters. Nonetheless, it is not ideal when shooting at different distance (not 100 yards).
  •       MRAD: 1 MRAD is approximately 3.6 inches (9.1cm) at 100 yards. Nonetheless, you may modify the right to the optic. If you miss 1 MRAD, you can adjust the scope again.
  •       Fully-coated: a coating layer can wrap all of the air-glass surfaces.

Decide your use purpose

Any optic used for hunting is not frequently a high magnification. They probably have bigger objective lens sizes because of the capability to create more light in for dark condition low-light environment. They could contain a heavy kind of reticle or illuminated one for a similar reason.


When considering the above factors, you should not miss out other criterions such as the sizing, its weight, ruggedness, and how easy it is to use if you shoot the scope in the field. It will need to shoot in several conditions.

Also, keep in mind that the quality of the optical is more important than objective size. A medium objective lens with good glass can reach fewer targets than a high-quality glass.
