Best Scope for 300 Win Mag

One cartridge that enjoyed immense popularity amongst rifle users is the 300 Winchester Magnum. People hunt deer and even bear with this rifle cartridge. It has a pretty powerful recoil as well, considering it is designed to deliver a hefty blow. So the scopes mounted on rifles shooting the 300 Win Mag have to be pretty durable. We have covered such scopes in our review section for the best 300 Win Mag scopes in the market.

The 300 Win Mag, as they call it, is one of the most used cartridges in hunting big games. There is a long history associated with the 300 Win Mag. It was created and crafted with much precision and released for use in the Model 70 rifle. The Model 70, which is dubbed the rifleman’s rifle, was famous for its use as a sports rifle in hunting contests.

The 300 Win Mag was designed so that most standard rifles could accept the cartridge without hassle. It is based on the predecessor .338 Win Mag and .337 H&H Mag cartridges. Since most standard rifles can use the 300 Win Mag cartridges, scopes can vary. So finding the right optics for your gun will be a difficult task. But we will do our best to help you out with this review.

Why Do You Need a Scope for Rifles Using 300 Win Mag Cartridges ?

The .300 Win Mag cartridges are relatively standard and mainly used for long-range hunting applications. If it was close range, even the average hunter might be able to hit a target 50-yards away accurately. When we move away from the 100-yard distance, it becomes difficult to shoot on point. Some people can shoot as far as 150 to 200 yards without the help of optics. But these are people who practice at the gun range.

To shoot a moving target like a deer or wild sheep, you need accuracy. Such accuracy is impossible without the assistance of good optics. The .300 Winchester Magnum is said to be good for about 1000 yards distance and more. If you plan on long-range hunting, you would need a scope to aim at your target accurately.

People use scopes on a slug gun which has a maximum of 200-yard effectiveness using powerful slugs. The 300 Win Mag has an effective range of up to 1100-yards at most. If you want to shoot even half that distance with precision, you need a scope. Your iron sights won’t get you anywhere that kind of distance. A good scope with a variable magnification of up to 30X will make sure you don’t miss a single shot.

What to Look for in Scopes for 300 Win Mag

While used to hunt for bigger games, like bears and deers, the 300 Win Mag is also a competition cartridge. Law enforcers also use it for sniping targets at a distance too. If you want help picking out the scope for your rifle that uses the cartridge, check out this comprehensive buyer’s guide.

1. Durability

Scope for the rifle shooting a 300 Win Mag has to be durable. That is because the cartridge has a mighty kick to it. The cartridge has been developed to maximize power, and so it creates a good amount of recoil. And because of that, if you mount anything on your rifle that shoots it, it needs to be durable. That includes the scope and, of course, so always check the material from which the scope is made.

The industry-standard these days is aircraft-grade aluminum which is pretty light but also very strong. It is durable and does not rust over time, making it an ideal choice for this application. It is also waterproof because it does not accumulate rust regardless of the moisture. And lastly, the lighter weight helps when you have to carry around a heavy rifle everywhere when hunting.

But even if the scope holds its construction well, it does not necessarily mean it’s suitable for your rifle. If you have to zero it in after every round fired, it is utterly useless. Now the 300 Win Mag is designed to have more power in the cartridge. The increased amount of gunpowder to create that power means massive recoil at every shot. Your scope needs to bear the brunt without losing the adjustments you made to it before firing the shot.

2. Magnification

If you plan to use your rifle to shoot a 300 Win Mag round at the range, you need some excellent magnification on your scope. If you can’t see a target correctly, it will be hard to hit it. Since the cartridge is suitable for at least 1000 yards, you will need some powerful magnification options. Something above the 10X zoom is going to be necessary.

If you plan on hunting deer or elk with it, then maybe something a little lower will suffice. 9X zoom is ideal for hunting-based applications, but buy something that will work in both scenarios. So you don’t have to buy two of these and just go over your budget uselessly.

3. Reticle

The 300 Win Mag is designed to shoot at distances. When shooting over distances, a standard crosshair does not cut it. You need something that helps you adjust your shot according to space. For such applications, BDC or MOA is the preferred reticle style to have in your scope. 

4. Other Features

Some other features to look for in your scope are whether the lenses are multicoated or not. A multicoated lens improves the light transmission of the scope. This helps you hunt better, even during dusk when the natural light is fading. Multicoated lenses also help reduce glare and reflection of light. Plus, it helps ease any dust buildup on the lens as well.

All optics are usually nitrogen or argon purged, and O sealed to avoid fog buildup on the lenses during cold weather. And if the reticle is on the second focal plane or the first focal plane. The difference is when you adjust magnification, the reticle stays the same throughout in the second focal plane.

5. Budget

A scope with more features and higher magnification means it is going to be expensive. You can find various budgets in scopes for 300 Win Mag. Depending on your need, a scope can go anywhere from 200$ to 2000$ and above. The bottom line, though is, the more remarkable features a scope has, the more expensive it tends to be. Of course, there is also quality, but all of the scopes in the reviews below are top-notch. Even the cheapest one on our list is pretty solid..

In all essence, scopes for the 300 Win Mag can be pretty expensive. But that does not mean there aren’t any budget options in the market. The Nikon Buckmaster II is a prime example of a great budget lens. But one thing that is consistent throughout all the optics is their durability. The 300 Win Mag is deliberately designed to have more extensive housing for gunpowder. This is to reach higher velocities, making it the preference for shooters and law enforcers alike.

But as you go up in price, you start to receive more features in your scope. Higher magnification, illuminated reticle, special features like the ArmorTek coating and LotuTec coating are just some of the elements present in the high-end scopes. But the budget will depend on your requirements. If you want to hunt at night, then choose a scope with an illuminated reticle. On the other hand, if you’re going to hunt at a long distance, choose higher magnification. 

Regardless of that, any of these scopes will suffice your needs more than enough.
