Best Scope for 300 Win Mag: Buying Guide & Top 9 Picks

What is the best scope for 300 Win Mag? The 300 Winchester Magnum remains on the top list of hunters and shooters of today. It’s pretty obvious from the fact that a lot of rifle-manufacturing companies, such as Winchester, Remington, and Browning manufacture 300 Win mag rifles.

The 300 win mag is the perfect range shooting cartridge to serve hunters when the need arises. This hunting cartridge can fire the 30-caliber bullets with precision, so it becomes an instant hit among shooters, hobbyists, and even military personnel.

It’s designed and made to fire heavier bullets at an effective short, medium, and long range when hunting just about any big game. Any rifle meant for the Win Mag to hunt a black bear, deer, moose, and elk can do its job better using the best scope for 300 win mag. In this buying guide, I’ll help you search for a best long range scope for 300 win mag to improve your performance.

What kind of scope for 300 win mag?

The 300 win mag is one of the most popular choices among hunters and shooters in the category of versatile cartridges because of its high muzzle velocity and energy to the point that it could help you take down any big game in North America up to Zimbabwe.

The cartridges are also favored by the target shooting, marine, and military communities for their excellent ballistic coefficient and muzzle velocity, allowing for flat bullet trajectory.

A good scope for this mag is one that can allow firing at shorter ranges for big game hunting and long range shooting from 50 to 1000 yards. In addition, it should be able to hold zero even with the high recoil round of the magnum.

Rifle scopes for a 300 win mag come in a wide variety, making the selection process a bit hard and challenging especially for beginners looking to get their hands on the real deal sighting device for their rifle or handgun designed to use the 300 win mag.

There are expensive and affordable varieties; each with unique features and characteristics to make the life of a hunter or shooter easier.

One of them is the expensive Swarovski scope for 300 win mag, like the SWAROVSKI Z5 3.5 to 18×44 Ballistic Turret scope. It’s a premium scope for people not concerned about the price. It offers a magnification range from 3.5X to 18X, excelling at all types of ranges from close, middle, and up to long ranges.

You can also find a Thermal scope for 300 win mag, another premium rifle scope with a higher price tag compared to more pocket-friendly ones. Typically, thermal imagery scopes or thermographic weapon sights combine an aiming reticle with a thermographic camera, which can be mounted on a wide range of small primary arms and a couple of heavier weapons.

However, if you’re not ready to use an expensive rifle scope, you’re in luck because there are sighting devices for your rifle that cost between $100 to $1000+ depending on the brand and features. But still, the price shouldn’t be the only factor to compare and buy your ideal rifle scope for the 300 win mag.


The best scopes for 300 win mag should be durable to deal with harsh environments, elements, and pressure. They must also be able to keep up with force, submersion, and temperature. Of course, this will be complete with preferably a lifetime warranty.

Magnification power

Used for both long range shooting and big game hunting, the 300 win mag is a versatile round. With that said, find one that offers more capabilities for variable power. Typically, the basic magnification is from 1.5-5x or 2-7x.

On the other hand, if you’re using the scope for long distance shooting, you can go for a higher range in terms of magnification adjustments provided that you pick a sighting device that is made with high quality optics. Nevertheless, I’d go for 3-15x magnification for a 300 win mag scope to be sufficient.

It would be a better idea to choose quality scopes that offer between two to seven times magnifications especially if you’re not planning to shoot at long distances. But if you’re mostly shooting long ranges, you might want to stick to scopes of 4-16X.


Especially if buying a quality scope with wide zooming capabilities, you’ll need quality glass and lens coating, as it can significantly contribute to light transmission as well as image quality. Scopes with a better quality coating also tend to have more resistance against damage from water, scratch, and other elements.

Check for HD glass, ED glass, or fully multi coated lenses if that’s something you can afford. Any of these would work better than a traditional scope having only a single coating layer. For example, a fully multi coated lens means having multiple layers on all air to glass surfaces.

Tube size

Typically, a larger tube is better in terms of durability and it has an equally larger range of internal adjustments in its turrets, although bigger tubes are more expensive than their smaller counterparts.

A larger tube is a wiser choice if you’re shooting mostly long ranges because such requires more adjusting of the elevation and windage. A larger tube is at least 30mm. It is also designed to come with a larger objective lens.

Objective Lens

Choose a larger objective lens if you’re using a higher magnification in targeting your subject, while a smaller one if you’re using lower magnification. But again, larger objective lenses tend to be pricier and heavier.

Eye Relief and Eyebox

A bigger eye relief makes your eyes safer from heavy recoil, but it can also be a disadvantage since it will put you in an uncomfortable position for your head and eye. The standard ones are from three to four inches. But of course, we know that the 300 win mag can result in high recoil. I suggest choosing an eye relief between 3.5 inches to 4.2 inches.

What about the eyebox? Some scopes have a small eyebox, meaning only having less than an inch of wiggle room for the placement of your eyes. This can lead to frustration when in the field, and this can become an even larger problem if you’re using a higher magnification.


MOA and Mil dot types are favored if using the ideal scope for distances beyond 800 yards.

Focal Plane: First or Second?

First focal plane varieties are usually more expensive and can be rarely found on cheap rifle scopes. They are better for reticle holdovers on all levels of magnification. Meanwhile, the second focal plane might only be accurate mostly only at the highest magnification. So if you’re planning to shoot long range, choose first focal plane scopes.

Reticle illumination

Choose one with a good illumination because it will help with faster target acquisition, as it will make the reticle more visible.

Reticle and turret matching

See if the turret markings match that of the MOA or mil dot reticle you’re using. So if you’re picking a mil-dot reticle, choose mil dot turrets.


They must be repeatable and precise and must be finger adjustable especially if you’re shooting at long ranges. But then, turrets shouldn’t be too loose, or you’ll make unintentional adjustments. You might also want to look for a zero stop/reset feature.

Parallax adjustment

This is especially important if you’re doing more long range shots because these help you reduce the need to align your eye to the sighting device and improves shooting precision.

What power scope should I put on a 300 Win Mag?

When looking for the best hunting scope for 300 win mag, you must also think about its power. One of the factors to consider is your distance.

What are the common distances you’re shooting? This will help you address the amount of power to put on your 300 win mag.

A scope with variable magnification settings is good, but you don’t have to go higher if you’re shooting mostly at short to medium length distances.

For many hunters, the most common distance is between 200 and 300 yards, meaning magnification between three and nine times will be enough.

But then if you’re using your scope for long range shots up to 1,000 yards, magnification at least 10X will be the wiser choice.
