Make sure to look at all the aspects of a scope before purchasing it as you want to have it be in one piece for more than one use.

Here are some factors to consider when looking to purchase a scope.


The best scope for your 300 Win Mag is the one that is best for your intended shooting distance. Make sure to buy one that is meant for long range shooting. The rifle is meant to be used for long range shooting, so you want to be able to go longer than 300 yards. You should test the scope out on the shooting range. You should be able to adjust the MOA easily so that the scope can be quickly adjusted for all distances.

2. Light

Your ideal scope for a 300 Win Mag is one with great light gathering ability. Since you might be shooting game in many different light conditions, you want one that operates well in any light condition.


The 300 Win Mag delivers a whopping recoil. You need to be sure that your scope is made with high quality materials so that it will not be obliterated the first time you use it.

4. Reticle

A reticle is helpful when sighting your target. Some scopes will have sights, others may have a BDC reticle and some may have a red dot. This is an optional tool, but nice to have as it only helps to increase your aim accuracy.

5. Magnification

The magnification level of a scope is probably one of the most important factors when looking to purchase one. Magnification is defined as the range at which the scope can multiple what the eye is seeing. Magnification level is based on individual preference.

You need to be mindful of the type of shooting you plan on doing as this will help you decide what your magnification ability should be with a scope.

6.Objective lens

The objective lens is an important aspect of the scope. It is located closest to the rifle’s barrel. The lens is designed to allow light into the scope, which helps you to view the objects clearly. The larger the lens is, the more light that gets in. Keep in mind though, that a larger lens is also a heavier one.


Weight is an important factor. If you are out hunting, a heavier scope will contribute to user fatigue so you should choose a lighter weight scope. However, if you are going to be shooting at a range, you can use a bipod or sandbag and that will make the weight of a scope a little less of a factor.

8. Windage adjustment

The turret for windage and elevation are necessary if you want to adjust the reticle to in order to shoot closer to the target. It allows you to further adjust for accuracy and increase your chances of successfully hitting your intended target.

9.Lens coating

Lens coating on a scope serves two purposes. It helps to cut down glare for you when sighting your target. The coating also allows the light to be transmitted effectively for you to see the target and your surroundings. It is not a necessary part of a scope, but if you find a scope with lens coating you won’t be sorry.

It will cause them to miss their targets and to not fully develop their marksmanship skills at the range too. The 300 Win Mag is the bigger bullet with the bigger kick.

Points to Remember

The 300 Win Mag is a powerful cartridge. If you are an experienced hunter or long-range shooter this is for you. This will pack a punch. When you are looking to purchase a scope, it needs to be well made since the recoil will destroy a cheaper version. This can even happen after the very first use. The heavy recoil of the 300 Win Mag is another reason why only very experienced shooters should be using them in the first place.

On its own the 300 Win Mag is great at distances of about 300 yards. Adding the right scope can take that maximum effective distance to 1000 yards quite easily. Just keep a few things in mind when purchasing your scope.

The first point is to pick a solid, well built scope. You should not just pick based on price, there are budget scopes for a 300 Win Mag available. A cheaper scope might be easier on your wallet in the short term, but you will be needing to replace it quickly as it will not stand up to recoil. Some cheaper scopes can actually be damaged with the first use.

You also want to consider magnification levels. By its very nature the 300 Win Mag is the ideal ammo for long range hunting of big game. On its own it is capable of 300 yards. A top scope for a 300 Win Mag will have the right magnification power for you to easily and accurately shoot out to 1000 yards.

Weight is also another factor to consider when purchasing the best scope for a 300 Win Mag for long range shooting. It is important to realize that the weight of the scope needs to be factored in to your combo. A heavier scope is generally a scope that has more options and capabilities. The tradeoff is the added weight, which can contribute to user fatigue. If you will be shooting on the range with a bipod or sandbags, weight of the scope becomes less of an issue. However, if you are in the field the weight is important. As your arm and shoulder become fatigued, you start to drop and then you will be missing targets. So when selecting the top scope for a 300 Win Mag, weight is a key factor.

Most scopes do have some type of lens coating. Although not as important as some other features to be found on a scope, lens coating is a nice touch. The purpose of coating is to help you see your target more clearly. The lens coating helps to cut down on glare and allows the scope to gather the image more clearly for you. The size of the objective lens goes hand in hand with lens coating as well. The size of the objective lens is a double-edged sword. A bigger objective lens will be able to gather more light and portray the image that much clearer and give you a bigger field of view. The downside is that the bigger the lens, the more the scope will weigh. So, this is another instance of where it is beneficial to know exactly what type of long range shooting you will be doing.

And the best tactical scope for a 300 Win Mag will have a reticle which is not necessary, but helpful. Having a BDC on a scope for a 300 Win Mag is a tool that new hunters, as well as the experts, can use to ensure accuracy. This feature is most advantageous when shooting out past 300 yards as it will help you refine your shot even further. Along the same line of reason is the addition of windage and elevation adjustments. A great hunter may not need to use them, but they are always helpful if they are present on your scope.


The 300 Win Mag is an extremely powerful cartridge. It is an excellent option for experienced hunters who enjoy long range and big game hunting. If you are looking to increase the maximum effective range of the 300 Win Mag, consider adding a scope to your 300 Win Mag rifle.
