Buying Guide for Scopes for .300 Winchester Magnum

Magnification

The magnification range is one of the most important aspects of a riflescope, if not the most important. The magnification is the range by which the scope can multiply the targeted image of the shooter.

To determine the magnification range of a riflescope, you need to take a look at the model name of the product. For instance, if you see 4-12x50mm, it means that the magnification range is between 4x and 12x, and the scope comes with an objective lens of 50mm.

This means that the scope has a variable zoom. There are scopes with fixed magnification; they can be 5x, 4x, or any fixed zoom. A scope with a 3x35mm model name has a fixed magnification of 3x.

If you want to shoot a moving target from less than 100 yards, a scope with a magnification range of 3x to 9x will be just fine. This is also a great magnification ratio for 300 Win Mag, as you can take down targets from 100 yards effectively.

Magnification is almost entirely preferential. Your choice entirely depends on your intended use for the scope. As such, you need to consider what you want to use the scope before making a choice.

The Size of the Objective Lens

The objective lens of a scope is another vital thing you need to consider before buying. This lens allows light to enter the scope, providing you with brighter and clearer images. The larger the objective lens of a scope, the more light it accumulates. Nevertheless, larger objective lenses increase the overall weight of the scope.

If you do most of your shooting in the shooting range than outdoors, or you hunt from dusk to dawn, then you would greatly benefit from a large objective lens. However, you also need to consider the added weight of the scope if you are out hunting, as carrying a heavy and huge scope might be counterproductive to your hunt.

As such, you need to consider your need and choose to sacrifice weight for more light or sacrifice more light for weight, the choice is yours. In all, we recommend you go for objective lenses within the range of 40mm to 50mm, as they allow for great light transmission and they are also relatively light.

Lens Coating

You will always want to invest in a scope that will not hurt your eyes despite providing you with sharp and bright images. When it comes to lenses, one of your biggest enemies is glare, as it can make great aiming almost impossible in some lighting situations.

Coated optics minimize the light reflected from the objective but it also transmits light effectively. There are different types of optical coating. However, the best among all, which is also the most expensive, are multi-coated lenses.

Fully coated lenses are also a great choice, as both the objective and ocular are coated. The majority of products on our top seven picks come with multi-coated lenses.

Conclusion

There you go! Our top 7 picks of the best scope for 300 Win Mag. If you own one of these rifles, then the next thing you need is the best scope to go along with it.

From our recommendations, the clear winner is the Leupold VX-1 3-9x40mm Compact Riflescope because of its great performance, magnification range, waterproof, fog-proof, and shockproof performance. It is durable and it comes with multi coated lenses.
