With its amazing performance, I can say that it is truly compatible with the needs of most shooters and hunters. It has a long eye relief, which sorts of prove how comfortable and dependable it is.

The next riflescope that I find special because of its numerous benefits is the Athlon Optics Argos BTR. One thing that makes it truly distinctive is that it is the first scope with a first focal plane that uses the 50-mm optic lens. It has a great magnification power, which is capable of retaining its reticle in different settings.

Such intensity levels also feature off positions that you can find in between each one of the settings. Another amazing thing about this 300 Win Mag tactical scope is its high level of color fidelity and resolution.
Such benefit is brought on by the built-in extra-low dispersion glass. With the fully XR multi-coated lens, I am sure of its ability to showcase better light transmission. One more thing I am so pleased with about the Amortek coatings utilized in this scope is that it offers protection to the lenses against oil, dirt, and scratches.

What Makes a Great 300 Win Mag Scope?
The .300 Winchester Magnum is one of the most popular .300 magnum rounds today. It is the ammunition of choice of many hunters, certain army units, and law enforcement officers. It has an almost perfect balance of power and accuracy for such a light round.
The rifles that can chamber .300 Win Mag cartridges include the Remington 783 Sendero SF II Bolt-Action Rifle, Weatherby Mark V Ultra Light, and the Winchester XPR Model 70 Sporter Bolt Action Rifle, among many others. However, what is the most surprising is that it can also be chambered by certain models of semi-automatic rifles.
The .300 Win Mag can fire accurately up to 250 yards. From this distance, the bullet will hit no more than an inch and a half above and three inches below the line of sight. This means that you can use a scope that is meant for medium-range targets – something with a magnification range of 3-9x or something with 2.5-10x is ideal.
At these distances, you can still set the scope in such a way that it holds zero so that the bullet will hit close to the center of the crosshairs. The best .300 Win Mag scope will actually depend on what you will be using the rifle for. If you will be hunting then you will definitely want a hunting scope that can help you get a clear sight picture and allow you to get a kill shot every time you pull the trigger.
Some people will tell you that there is no need to put a scope on a .300 Win Mag rifle but then again, it will not hurt the performance if you did. In fact, you can benefit greatly by installing the best scope for 300 win mag on your rifle.
Factors to Consider when Buying a Scope for 300 Win Mag
To boost the likelihood of you getting the right scope for 300 Win Mag, ensure that you spend time scrutinizing these factors:
One of the most important, if not the most significant, aspects of a riflescope is the magnification. This is the range by which the scope can multiply what the naked eye of the shooter can see. To determine the power magnification of a scope, you need to look at the model name.
For instance, if you see the numbers 3-9x32mm, it means that the scope has a 32mm wide objective lens and can magnify targets by 3x up to 9x zoom. This means that this is a variable zoom scope. On the other hand, a 4x32mm scope has a fixed magnification of 4x.
Magnification is almost entirely preferential. If you want to shoot at moving targets from under 100 yards, a scope with a magnification of 3-9x will do just fine. This is also the preferred zoom ratio for .300 Winchester Mag rifles as this kind of round only has an effective firing range of 100 yards.
Objective lens size
On a scope, the objective lens is the one that is closest to the barrel of the rifle. This lens lets light into the scope, making the sight image brighter and clearer. The larger the objective lens, the more light it transmits. However, it also makes the scope heavier.
If you will be spending most of your time shooting in the shooting range than outdoors then having a scope with a huge objective lens will be the best choice for you. On the other hand, a large objective lens will only be a hindrance when you are out hunting because carrying around a rifle with a huge and heavy scope will be counterproductive to your hunt.
You need to think about where you will be using your rifle the most. If you will be mostly plinking in your local range and you will be using sandbags or a bipod to hold your rifle steady, weight will not be much of an issue so get the rifle scopes with larger objective lenses if you fancy.
However, if you will be using your rifle more on hunting, then you need to get a lightweight scope, because stalking your prey with a top-heavy rifle can be very difficult.
Elevation and windage adjustment
The windage and elevation turrets are used to adjust the scope’s reticle pattern in relation to where the bullet hit the target so you can accurately set your sights to hit. This means that the bullet will hit relatively nearer to the center of the reticle the next time you shoot.
When you look into the scope, you just want to see a bright image but without any glare that can hurt your eyes and make aiming properly near impossible. Optical coatings aim to reduce the amount of light reflected by the objective lens but at the same time allow it to transmit a lot of light.
There are four primary types of lens coating available. The first one uses coated lenses characterized by either the objective or the ocular lens that features a single layer of anti-reflective film. Another type is the fully coated lens. Here, both the objective and the ocular lenses have a single layer of anti-reflective film.
There is also the multi-coated lenses with either the objective or the ocular lens having multiple coats of anti-reflective film. Lastly, you can choose the fully multicoated lens with both the objective and the ocular lenses having multiple coats of anti-reflective film.
The reticle, also called the crosshair, is the part of riflescopes that the shooter will use to gauge where the bullet will hit. Looking through the riflescope and using reticles is the same as using the iron sights but with more accuracy. There is really no “best” reticle. Some people might like the generic crosshairs. Some might want the one with the BDC reticle or otherwise known as the bullet drop compensator and windage chart while others prefer just having a red dot.
There are two types of focal planes in riflescopes, it is either in the first or the second focal plane. In the second focal plane, the reticle is found on the end of the erector tube, which is the part nearest to the ocular lens. In this configuration, the reticle will seem to get larger regardless of the magnification of the image.
When the reticle is on the first focal plane, it will remain the same six when you zoom in into the target. In this configuration, the reticle is in front to the erector tube. This means that the reticle will not change size regardless of the magnification level you set the sight to.
If this is the first time you will be buying a riflescope, you need to learn about the tube size, mainly because you will need this information to ensure that you purchase the right- sized mounting rings for your brand new scope.
There are generally two sizes of tubes – the 30mm tube diameter and the 1 inch. There are really no benefits that one has over the other. A larger tube does not mean that it lets more light in.
The real reason for tube size is that you do not want to get stuck with a 30mm scope and scope rings that are one inch in diameter. If you live in the US, most riflescopes are built using one-inch tubes and in Europe, the optics are usually 30mm.
Frequently Asked Questions
What size scope can you put on a 300 Win Mag?
By size, if you mean the tube size, you can use both the 30mm and the one-inch diameter tubes. You just need to use the appropriate mounting rings. If on the other hand you mean the size of the objective lens then the answer will depend on your preference and your intended use for your scope.
If you will be using the scope on a hunting rifle, then you can use one that has a big enough objective lens to let in enough ambient light from the surroundings.
The truth is you can put whatever size of riflescope you want on your .300 Win Mag rifle. Just as long as the objective bell does not touch any part of the rifle and it does not interfere with the bullet ejector and the bolt action then you are free to use any size of scope that you want.
What kind of scope can you put on a 300 Win Mag?
Again, there is no right or wrong choice of riflescope for 300 win mag, as long as you can use the rifle properly. Speaking of use, you should choose the right riflescope for how you will be using the rifle.
For instance, if you will be using the 300 win mag for hunting small and medium sized game, it is best that you choose a riflescope that is shock, water and fog proof because you will be spending a long time out in the cold forests stalking your prey. When you do spot your target, it would be really nice if you do not have to wipe off the fog that built up on the lenses of your rifle when taking aim.
Now, you could also use a long-range scope on your 300 win mag rifle, but it is much better to just stick to medium-range scopes for now. The 300 win mag ammo is only accurate up to 200 yards with the bullets hitting a couple of inches above or below the line of sight.
Go beyond that, like say 700 yards, and the bullet will hit more than five feet below your line of sight, which means you will have to compensate quite a lot for bullet drop, so much so that you will be aiming some distance above your target to actually have a chance at hitting it.
How to sight in a scope on a 300 Win Mag?
- Install the scope properly
You need to make sure that your scope bases fit your rifle properly, and that your scope also fits the scope mounts properly. If this is your first time using a scope, it is best that you buy a one-piece scope base and mount instead of getting a two-piece mount and scope rings setup.
- Adjust your eye relief
You need to adjust the eye relief, which is the distance between the end of the scope and your eye, properly so you can avoid really serious injuries from your recoiling rifle. The 300 win mag has quite a kick so you should get a scope that has an appropriate eye relief.
If you do not set the eye relief properly, the recoil from the 300 win mag will kick the rifle backwards and the eyepiece will hit your eye, which could cause all sorts of injuries, like a shattered eye socket, or it can even cause blindness if your eyeball gets hit.
- Level your rifle
To properly sight your scope, you need to place your rifle on a stable base for a secure range shooting position. It is near impossible to sight a scope while holding your rifle on your shoulder and standing up. You can either position your rifle on a shooting bench, or you can use a bipod.
- Align the crosshairs
You need to align the reticle of your scope before you start zeroing it in because if it isn’t properly aligned (called a canted reticle), your shots will start missing either to the left or the right of the center of the reticle.
- Set up your minute of angle
Most quality scopes allow reticle adjustments of ¼ MOA (minute of angle) increments, which means that ¼” movement per click when zeroing in at a distance of 100 yards. Most rifle users use either 1/8 or ¼ MOA clicks when sighting their .300 Win Mag scopes.
- Test fire in three-shot groups
Fire three-shot groups and take note of where they land. The most common way to sight in is slightly high at 100 yards, and then dead center at 200 yards. However, you can choose to sight your scope whichever way you prefer.
It is best that you are very familiar with your MOA so that you can adjust quickly for different distances. Keep tweaking your sight until you find that sweet spot that you can use for all distances.
The best scope ring is the one that can hold your scope firmly and securely. It should be something that will stay put in its base while also having the ability to effectively hold zero after every shot.
Even though you will not be able to hit targets from 700 yards reliably using the 300 win mag, you can still expect it to be very accurate from 200 to 250 yards. If you want to increase its accuracy and the speed of target acquisition, you will surely do well if you add the best scope for 300 Win Mag to your rifle.
A seasoned hunter might scoff at the idea but the truth is that any kind of firearm will benefit greatly if they have a scope installed, and anyone who says otherwise is most likely lying.
