How to Choose a Scope for 338 Win Mag

Buying the best scope for 338 Win Mag isn’t something you do on a whip. Here are the key things to take into account before settling on any specific product.


For such a big caliber, you need a scope that is built for long term use. Any cheaply built scope will fail to handle the recoil the round generates and end up being damaged after a few sessions of hunting.

To avoid that, go for a scope that is built using high-quality materials like aluminum or magnesium. The scope you get should also be shockproof, impact resistant and rated for recoil resistance.

Lens Coatings

In a scope, lens coatings play a big role of determining the amount of light transmitted. Go for a scope that has several layers of anti-reflection coatings applied on all air-to-glass surfaces. The more layers of lens coatings are applied, the more light will be transmitted and the brighter the images will be.

The best scope for 338 Win Mag should also be made with premium glass elements to enhance resolution and color accuracy.

Objective Lens

Another important thing to consider is the objective lens whose primary role is to collect light inside the optics. The larger the objective diameter is, the more light the scope collects and the wider the field of view it generates. A tip is to get a scope that has a large objective lens of between 40mm and 50mm. Such scopes offer the ultimate balance between weight and light collection.


When hunting, you need to have lightweight gear that don’t weigh you down as you move from one point to the other. Look for a scope that is durable but ultralight for easy carrying in the field. Having a lightweight scope is also beneficial for recoil dispersion.

Eye Relief

Another feature that is also important to factor in is eye relief. This is a measure of how far the scope has to be from your eye and still be able to see a full field of view. It is essential in that it determines how comfortable your glassing will be. We recommend that you get a scope that has an eye relief of 3.5 inches and above.
