The 6 Best Scope for 300 Win Mag Rifle in 2021

1. Vortex Optics Crossfire II – Best 300 win mag scope

Vortex Optics Crossfire II Adjustable riflescope

Well, I’ll talk about some of the features of Vortex Optics Crossfire II and find out the reasons why you should buy it and if it’s the best scope for 300 win mag. This scope is not only for 300 win mag. It is listed in my best scope for 22lr rifle also. Let’s first talk about the things that this scope comes with.

The scope comes in well packed in plastic wrapping, the box also contains rifles scope manual and foams are placed well so that the scope doesn’t get damaged while shipping.

One thing that you must remember is to read the warning label. If you haven’t, it tells you not to exceed 18 inches/pounds of torque on the ring’s screws. It also comes with lens covers which keeps your scope in a better condition by keeping grime and dirt off from your scope.

The scope doesn’t come with an amount, so you’ll have to get the amount separately.

On the back, it also has a focus range which helps you get dialed in. The turret caps are placed nice and tidy and they have covering seals there as well. The turret has an audible click and the travel per rotation is 30 MOA. Both the side and top turret are pretty similar.

One of its’ unique features is V Brite Reticle. This battery-powered reticle gives your dot an electronically powered mark which is quintessential for actions in low light situations. This illuminated red dot is an awesome ad on which gives it an edge over similarly classed scopes!

The weight of this scope is 1 pound which is quite heavy for a 1 to 4. For optics of such weight Id want more power and clarity and last but not least more magnification. Yet, it’s a quite good scope for 300 win mag.

This scope is waterproof, a small fog develops after getting it into the water but that goes away after some time and that’s normal. it also claims to be fog proof and shockproof!

Here is another review for Vortex Crossfire II 3-9×40


  • V Brite Reticle.
  • Effective waterproofing.
  • Designed for long-distance shooting.
  • Aircraft-grade aluminum body.
  • Lifetime warranty.


  • Heavy scope
  • Extremely fragile with slight over-torquing

2. Nikon Buckmasters II, 4-12x40mm, BDC

Nikon Buckmasters II  4 12x40mm BDC Rifle Scope

Nikon Buckmasters II is a highly popular affordable option for your rifle. One of the qualities that have to be talked about is its accuracy. The recoil of this scope is pretty good. The well-designed glass will give you enough light to pinpoint your targets. Glasses are also crystal clear which brings absolute contentment to the hearts of shooters like you!

The turrets are amazing and they come with intelligent lift-twist-drop control and its adjustments are highly audible, you will hear each click! So, the turrets are just amazing in this scope! It’s a quite good scope for 300 win mag.

3.75 eye relief is quite good and most modern scopes have similar eye relief. Eye relief in Buckmaster II will give you a longer shooting time.

Another thing that always surfaces in the discussion of scopes is the warranty. Nikon offers you a warranty of 30 long years which is quite fascinating! The warranty though is not transferable, which means it will only apply to the original buyer.

Nikon claims that this scope is effective in hunting animals. They also profess this scope to be water, fog, and shockproof.

A bright-sight picture is what I’d call its’ strength. You will be able to enjoy shooting with this scope in darker conditions. And with the improved accuracy, your hunting experiences are expected to be satisfactory.

Offering excellent quality in their product is something that created the Nikon fan base and they continue to maintain superb quality in designing scopes in Buckmaster II as well. Here is another Nikon ProStaff 3-9×40 Review.

The thing that separates this scope from any other scope in the market is its pricing. The quality Nikon offers at the price is just unimaginable.


  • Great quality.
  • Highly affordable.
  • Better than other scopes at the price.
  • Great hunting capabilities.


  • Reticle could have been better.
  • Parallax not adjustable.

3. Athlon Optics, Argos BTR, Riflescope, 6-24 x 50  


Athlon can be another option for your 300 win mag. There are some things which are good about this scope and it has a large market base as well. Yet there are some things which are not quite up to the mark which I’ll discuss now.

Let’s first get through the turrets. Tbh, the turrets are audible but still kinda mushy, could have been better, over spinning can easily occur if you’re not careful enough with it. This can mess you up if you’re competing in events that require quick shooting maneuvers.

The one feature which makes it unique is its first focal plane reticle, a sort of reticle which shrinks or grows along with zooming and zooming out. Thus, it is expected to have quick target engagement while requiring low power. This is something that should bring satisfaction to the shooters.

Athlon scopes don’t have many mechanical troubles so this scope too can be expected to perform well.

Glass quality and brightness is something that is lacking in this scope. Anything above 18 power becomes difficult to handle for this scope. Plus, shooting at dusk would be a hard thing to do for shooters with this scope.

Optical clarity under increasing power is kinda bit lacking. Again, this is something that is going to cause you trouble in intense situations.

Athlon Argos BTR also comes with scope caps, they’ll help your scope stay clean and clear. In all the Athlon scope this is perhaps one of the best scopes at this price.

It’s a budget scope in the high-end scope market. So, the features it offers are quite amazing if you compare the price. The overall quality with the price it comes with is quite good. Because you’re getting a 30 mm tube, side focus, and tactical turrets all within a short price range, which is astonishing! Add with it FFP and illuminated reticle, these make it an adequate choice for shooters.


  • Lifetime warranty.
  • First focal plane.
  • Illuminated reticle.
  • Aircraft-grade aluminum.


  • Turret may overspin.
  • Intolerant to power.

4. Vortex Optics Viper PST Gen II Riflescopes 

Vortex Optics Viper PST Gen II Second Focal Plane Riflescopes

Vortex Optics Viper Gen II is a long-range shooting rifle scope. This is a second focal plane rifle. It comes in a classy matte black box.

Another feature that Vortex very publicly advocates for this scope is its MOA reticle. The reticle is illuminated, it’s very bright and it has got several different settings.

One thing that you should keep in mind is that this is a power-hungry optic. Batteries in this optic may not last long, at the highest setting it may last for 2 days max. Better if you always have some extra batteries for this power-hungry beast!

This scope also has an adjustable parallax system in it, which starts with 25 yards to infinity. Let’s check How to adjust a rifle scope.

Well, if you’re considering buying a budget scope, this perhaps is not your thing. It’s a scope for serious shooters who truly has a passion for shooting or you have a pretty expensive rifle where you don’t wanna use a cheap scope.

The glass of this beauty is highly clear. Thus, you are expected to get better vision and better shooting. The scope is multicoated and Vortex also claims it to be water, fog, and shockproof. All in all, it is a tough scope which you may use in any rifle.

It’s a type 3 hard anodized coated body that is resistant to corrosion. Matte black finishing gives it a killer look!

Eye relief it has is about 3.4 inches which is quite good. It goes better with a cantilever mount.

One thing that you mustn’t forget is how sharp the edges are. If you don’t have a sharp edge it will be a disaster for you in high magnification. The visual you will get will be blurry and fuzzy which will shatter your shooting experience. But this scope offers you great edge-to-edge clarity, quite fascinating!

With Clear glass, good light transmission this is just a beauty overall!


  • Big turrets.
  • Knurling on the turrets.
  • Parallax setting.
  • Good reticle.
  • Great re-zero ability.


  • Low battery life.
  • Expensive.

5. Leupold VX-3i 3.5-10x50mm Riflescope 

Leupold VX 3i 3.5 10x50mm Riflescope

Well, the first thing that I should talk about this scope is the packaging it comes in. Beautiful matte black box with golden writing just looks breathtaking. It contains the owner’s manual, sticker, a piece of written information on the custom dial system, and a cover.

One of its’ key features is that it’s extremely lightweight. It’s only 13.1 ounces which is incredible for the scope of this class. Its 1-inch tube makes it one of the best scope for 300 win mag elk hunting sessions.

Another thing that you should keep in mind about this scope is that it has a staggering 52 MOA adjustments for elevation and windage, that’s a large number of adjustments.

Like the other Leupold scopes, it’s pretty tough. Made with 6061- T6 aircraft quality aluminum which gives it a strong body. Comes with strong housing, like the other scopes of this grade Leupold too claims this scope to be water and fog-proof.

Well, let’s come to one of the biggest selling points of this scope. Yes, you will get a lifetime guaranty for this scope. This goes to show how serious and confident Leupold is about its products. You will get the taste of made in US scope quality with this rifle.

It also has a unique twilight max light management system. Which Leupold tells us will allow you to get a better view in shadows, perfect for hunting at dawn or dusk, the light-gathering capabilities of this scope are satisfactory.

The matte black finishing is spectacular. The quality of the glass is pretty fine. Gives you the detail of the visual. It is perhaps the best long-range scope for 300 win mag.

If you’re someone who craves a truly high-end scope but cannot afford to have one then this is for you. You’ll get the high-end scope features within your price range.


  • Bright.
  • Hold zero best.
  • Easy to use.
  • Various MOA adjustments.
  • Aircraft quality aluminum.


  • Can be expensive for some.

6. Vortex Optics Razor HD Gen II First Focal Plane Riflescopes 

Vortex Optics Razor HD Gen II First Focal Plane Riflescopes

Well, let’s get straight into the details of this scope and begin with the glass quality of this. The quality of glass that comes with this scope is excellent, it has low tunneling. Even in the maximum 18 power, it has a clarity that covers one edge to the other. All in all, amazing glass quality.

Reticle design in this scope is another of its strengths. It’s outstandingly detailed that it is hard to come by on regular scopes. This reticle offers you a vast array of functionalities. A good fit for your 300 Winchester magnum rifle. It could be the best tactical scope for 300 win mag that you can use.

Let us now get a closer look at the turrets! Its turrets are locking turrets you just need to press it down to lock it. You also get locking windage and elevation as well. Even the illumination can be locked and unlocked. Turrets are highly tactile. And, yes, they are audible and not mushy. So, you can dial quickly too. Finally, the turrets of this scope are amazing.

The reticle quite amazingly illuminates everything that is there which includes windage holdover as well. Yet the black reticle can be a problem while shooting against darker backgrounds.

Overall the design of this masterpiece is outstanding. Despite the intelligent design, this scope is really simple and easy to handle. Uncomplicated yet handy this is absolutely a true genius design.

The finishing of this scope is really good. All the segments of this scope are smartly built.

Okay, weight can be one of its drawbacks if we have to talk about it. At 48.5 ounces this is quite heavy. For those who are looking for a lightweight scope Vortex Razor HD II is perhaps not the thing for them. But its’ weight is quite justified with the specs it comes with. Elevation adjustment is something that could be improved in the scope. But all in all, this is one absolute tank! For your 300 win mag, you can get it any day!


  • Outstanding glass quality.
  • Simple to use.
  • Smart design.
  • Superior locking designs.
  • Illuminated reticle.


  • Quite heavy.
  • Elevation adjustments could be improved.

Buying guide to get the best 300 win mag scope

Okay, getting the desired scope for your rifle isn’t an easy job. There are thousands of choices in the market and you’ll need to find the best sorta scope that fits your requirements as well as matches your rifle. Our guide will get you the required understanding that helps you choose the best 300 win mag scope.

Something here: How to use a rifle scope for hunting



The reticle is a series of markings printed on the glass of the scope to help you with the correct measurement for shooting. Getting a quality reticle in your scope is something that you should always look for.

The reticle design of the different scopes is not the same. So, getting a good reticle in your scope is recommended for a satisfactory shooting experience.

Glass quality


One thing that you must think about your 300 win mag scope magnification is its clarity. The quality of the glass of the scope is something that is a prerequisite for a decent shooting experience. You Must find the scopes with the best glasses. Try to find glasses with no tunneling. It increases the optical quality

Eye relief

Sometimes when you’re using a scope and with magnification, it starts to lose the image quality. It could be because you have the wrong eye relief. When you get a scope with a large objective or high ring, they seem to struggle to get your face in line with the scope. You can get a cheek rest as well for better eye relief. All in all, you should get a scope that offers you the best eye relief for more quality shooting time.


Turrets are important in terms of getting a scope for comfortable shooting. Try to see if your scope has locking turrets. This will give you the advantage of locking into your desirable adjustments. Otherwise, your desired adjustments may change during the shooting. 

Check here: How to adjust a rifle scope before hunting


You must choose your desired shooting range. Depending on your required shooting range you will choose the magnification of your scope.

There are two types of magnification systems in scopes. One is fixed another is, variable. Fixed magnification cannot be changed and you’ll have to stick with the installed magnification range. With variables, as the name suggests, you’ll be able to change magnifications as you want. Most of the recent and advanced scopes use variable magnification.


Another important factor that you always should check before buying a scope is its strength. Most of the scope manufacturer claims their scope to be water, fog and shockproof. Make sure your scope has those features before getting them exposed to water and other difficult conditions. Try to get scopes that are made with aircraft-grade aluminum. They are expected to be stronger than ordinary scope materials.


Weight is always something to think about before buying a scope from the market. If you’re not accustomed to heavy scopes you’ll certainly regret having one. The lighter scope will give you more reflex and flexibility. On the other hand, some high-end scopes tend to be heavier. So, before buying a scope you must understand if it suits your shooting style.


The warranty has become a selling point of most of the scopes right now in the market. Tbh, scopes that have true quality in there don’t need a lifetime warranty. Yet, offering a warranty gives in the user’s mind a sense of security and a sort of assurance that they will be looked after even after the purchase.

You can choose a scope that offers you a lifetime warranty. But also keep in mind the transferability of the warranty, you may not use a scope for your entire life and may want to sell it to someone for a possible upgrade.

Which scope is best for 300 win mag? (My personal opinion)

There are two scopes in particular which I’d like to talk about in this discussion. First off, the Nikon Buckmasters II, 4-12x40mm, BDC, riflescope should be mentioned. It’s a budget scope that will give an overall quality. With great eye relief and turrets, this is my pick as the scope for 300 win mag within a limited price range.

One other scope that can be added is the Leupold VX-3i 3.5-10x50mm Riflescope. It’s a tank! With great lighting and various MOA adjustments, this will give a flavor of high-end scopes. But Leupold brings this at a price that is hard to find elsewhere. This US-made beast is perhaps the greatest 300 win mag scope.

Final Words

Getting a quality scope may not be a serious matter of importance to some. But to the millions of gun lovers around the world, it is a matter worth discussing and an affair with much examination and study.

So, going through the details of the scopes you’re going to buy has become important. Understanding the characteristics of the scopes is required for acquiring better scopes.
