What Makes a Great .308 Scope?

The .308 Winchester is probably the most popular hunting rifle in the United States, and maybe even the whole world. Not only does it have an excellent range (1000 yards according to the USMC), it is also one of the most consistent performing ammunition in the market today.

If you want to make the best use of its long effective range, you will need a scope that can give you a good sight picture up to 800 yards. Note that unless you are an army-trained sniper, aiming for 1000 yards is a bit challenging.

The .308 Winchester also has little recoil, so eye relief is not a priority. Still, you should not place your face too close to the eyepiece, because you might not be able to brace yourself enough to prevent the rifle from kicking back. This means that something with around 3-1/2” to 4” eye relief will be fine.

The magnification power and other aspects of the scope will depend mostly on where you will be using your rifle. If you will be using it for hunting, you need to keep the scope as lightweight as possible. When you are game hunting, you want to get as close to your target as possible. You will not risk it by shooting at it from 800 yards away. At most, you will be shooting from 150 yards, even when you are using a .308 Winchester. A scope that maxes out at 9x or 12x is more than enough for your needs.

What Magnification Do You Need?

In general, the type of scope magnification that you should get depends on for what you will be using the rifle the most. If you will be using the rifle for game, elk, or deer hunts, and you will only be shooting up to 150-200 yards, a scope with around 6-9x power will suffice. When you are hunting in the woods, your target will not be waiting for you while you make slight adjustments for windage and bullet drop, and of course, you will not be shooting from 800 yards away.

On the other hand, if you will be using the .308 rifle in the shooting range, and you will see if you can do the 1000-yard shot that USMC snipers routinely do, then you should get a scope that has a high magnification power—something that has 24x magnification range is the minimum that you should strive toward. Also, remember that something that has a BDC reticle will make taking long range shots much easier.

Should you choose a fixed magnification or a variable zoom scope? If you are out hunting, you need something that is convenient to use. Choose a hunting scope that you do not have to tweak to get a good sight picture. A fixed magnification is the best choice.

You just peek into the scope and place the crosshairs on your target and then pull the triggerno fuss or mess. If you will be shooting in a range and you have all the time in the world to line up your shot, then a variable powered optic or variable zoom will work the best.

Factors to Consider when Buying a Scope for 308

So what are the things and factors to look out for when shopping for a good .308 scope? Here are a few:

The Correct Magnification Power Is Essential

When you are buying a scope for a .308, the magnification power is the first thing that you should check out. How much magnification you need will depend on your particular use. Note that just because a scope has a higher magnification power than another, this does not instantly mean that it is better all around.

Sometimes, you will not need ultra-high magnification power, especially if you will be using the rifle for deer, game, or elk hunting. Regarding whether or not a fixed zoom or a variable zoom is best, it is subjective. For hunting, you need your scope to have the ability to acquire the target easily the moment you peek into it.

A Large Eye Relief Is Less of a Concern

For the .308 Winchester, the eye relief is not much of a concern, mainly because it does not have quite as much recoil as other ammunition with the same effective range. With that said, it does not mean that eye relief should be completely ignored.

If you are a beginner at using a rifle, you might not be able to fully absorb the recoil of the rifle using your shoulder. This means that it, along with the scope, will have a way to go before it stops. If your eye socket is in its way, it will hurt and possibly cause serious injury. Get a scope with at least a 3-1/2” to 4” eye relief.

Keep in Mind the Weight

The weight of the scope can be due to a number of sources. Most of the time, the majority of a rifle scope’s weight comes from the lenses it has inside, so you will need to make a compromise at this point.

For instance, if you want a light scope, then something that has a fixed 9x zoom with a 42mm objective lens is what you should get. It might not be usable for hitting targets 900 yards or more away, but if you will be using the scope for hunting, you will love having something that will not add any more weight to your gear.

Choose a Reticle That Matches Your Shooting Style

The reticle or crosshairs in your scope will depend on how you like to shoot. For instance, if you like shooting long distance, a BDC reticle might be good for you. These reticles have millings so that you can take into consideration the bullet-drop, as well as windage and elevation adjustments with every shot.

There are many different kinds of reticles you can choose from, and there is no one or two reticles that are actually better than the rest. It will all depend on your shooting style and which reticle you are comfortable using.

The objective lens is the one at the front of the scope, and its job is to allow light to come into the scope and give you a clearer sight picture. The bigger the objective lens is, the more light gets into the tube and the clearer the sight picture you can get. This is great when you are shooting in poor lighting conditions and you need to get a clear shot at your target.

The Objective Lens Will Minimize Extra Light

However, the bigger the lens system is, the heavier it is. You need to find some sort of middle ground so you can get the best image quality, but not add quite as much weight to your rifle. For hunting, a 42mm objective lens will do fine, although you could also get away with using 50mm, if you can find one with a fixed zoom so it will not be too heavy.

The Parallax Adjustment Is Important for Long-Range Scopes

In short to mid-range scopes, parallax is not really an issue because those scopes are already parallax-adjusted to those ranges. However, on a long-range scope, parallax is something that you have to deal with constantly.

Parallax happens when the reticle is not in the same focal plane as the target. As a result, the reticle will move about over your target when your eyes move in relation to the scope. If you are looking for a long range scope, find one with parallax adjustment. Those are the ones with a turret at the top of the tube.

Weatherproofing Avoids Damage

This is extremely important if you will be using your rifle primarily for hunting. It is quite rare that when a person goes out hunting, it will be a perfectly clear day. Most of the time, you will be hunting in the rain, thick fog, or a combination of both.

You will need a scope that can handle whatever mother nature can throw at it. Ideally, you should get a scope that is waterproof, dustproof, fog-proof, and also a bit shockproof, so you do not have to worry about banging your scope on the trees and rocks while you’re hunting.

The Lens Coating Eliminates Light Reflection

The lens coating of a rifle scope enables the lenses to absorb as much ambient light as possible from low light environments, while reducing the amount of glare that will make it hard for you to aim properly. The lens coating also reduces the amount of light reflected by the lenses.

This is important because reflected light does not only add to the glare. It also gives out your location to your target. Lens coating comes in coated (single coat, single external lens only), fully coated (single coat, both external lenses), multi-coated lenses (multiple coats, single external lens), and fully multi-coated optics (multiple coats, both external lenses).

Frequently Asked Questions

What size scope should I get for the AR .308?

There are many different sizes of scopes that can fit on an AR .308, and there is not one that can be called the “best.” It is purely subjective. You can use any size of scope that you want. You can even use the biggest one available if you want, as long as it does not interfere with the functions of the rifle. However, if the scope that you mount on your rifle does not suit the use that you are planning for it, then it is worthless.

The objective lens is one of the parts of the scope that dictates how big it will be. For instance, a scope with a 50mm objective lens is much bigger than one that has a 42mm objective. Although the 50mm objective scope can gather in more light, it is much too bulky for most people to use it for serious hunting. Choose the size of scope that fits your needs.

How do you sight in a rifle with a .308 scope?

It does not matter if you have a sophisticated rifle scope mounted on your .308 rifle. If it is not sighted in properly, you will not be able to use it to hit any target at any range. If this is the first you are using a rifle scope, here are the steps on how to sight it in properly.

1. Ensure that the scope is installed properly:

Almost all modern rifles available today already come with built-in mounting systems for scopes. Regardless if your rifle comes with pre-drilled and tapped holes for screwing in scope bases, or if it has a grooved rail system, like the Weaver and Picatinny rail systems, you need to make sure that the scope mounts and rings that you will get actually fits the mounting system of your rifle.

Do keep in mind that there are some scope rings that will only fit in certain types of scope bases, which is why it is of utmost importance that all your components match each other.

2. Adjust the eye relief:

Position your eyepiece so that you can see a clear image when you peek into the scope. You need to fine tune the scope and create the right amount of eye relief, which is the distance between the back end of the scope and your eye.

This is a key component to sighting your scope because you have to be sure that when you fire the rifle, the recoil will not send the scope far enough to smack you in the face and cause serious injury.

3. Set your rifle on a level shooting position:

To sight your scope properly, you need to set it on a stable shooting position. You can either use a bipod, or better, clamp your rifle on a shooting bench with a mount.

The thing about the rifle mount is that it can absorb almost all of the recoil, while still holding your rifle securely. There are many different mounts that you can choose from, but if you are going to get one, choose the one specifically designed for scope sighting.

4. Align the reticle:

Most beginner shooters do not take into consideration the alignment of their scope’s reticle when they are sighting in their new scopes. When the reticles are not aligned to the directions of the elevation and windage adjustments, it is called “reticle cant.”

This is important, especially for .308 scopes, because they are meant for long range. A reticle cant can result in your shots missing either right or left of the target, especially if the target is beyond 250 yards away.

5. Set the Minute of Adjustment (MOA):

Setting your scope’s zero involves several steps, and it is easiest to do it in an outdoor shooting range, mainly because you will need to set targets at multiple distances that are at least 100 yards away from you. In addition, you need to keep your rifle stable, so you will need a mount for it.

Most rifle scopes allow you to adjust the crosshairs in ¼ MOA increments, which equates to ¼” movement for every click when sighting at 100 yards. Most professional hunters set their MOA to 1/8” and ¼” MOA click value. To make your bullet hit an inch, or one MOA at 100 yards, you need to turn the elevation or windage turret by four clicks. The click value increases by ¼” per 100-yard increase in distance.

6. Fire three shot groups:

Once your rifle is on a level base, fire three shot groups at the target, then take note of where your shots land on the target. Depending on your use, you might want to sight in slightly high at 100 yards away then aim at the center of the target at 200 yards—It depends on you how to set your MOA. The important thing is that you are familiar with your MOA settings so you can quickly adjust at different ranges.

7. Keep tweaking until you are satisfied:

You should try different distances and repeat the sighting in process so you can consistently hit grouped shots that are close to the bull’s eye, regardless of how far they are. Keep in mind that you should not just factor in the rifle scope and distance from the target, but also the direction and strength of the wind and other environmental variables.

Nikon M-308 vs. P-308: Which one is better?

Between these two riflescopes made by Nikon, the M-308 is the higher-end model. These two riflescopes have similar features, but the M-308 has a couple of “premium” features that are not in the P-308, including the parallax setting, higher magnification, and large range of FOV and eye relief.

However, the P-308 sells for just half the price of the M-308. This is also combined with the fact that the additional features of the M-308 are somewhat niche features for long-range shooting. For value, the P-308 is the better choice of these two scopes.

Leupold Mark AR MOD 1 3-9x 40mm vs. Nikon Buckmasters II 3-9x 40mm Riflescope: Which one is better?

These two scopes from different companies have similar features. The Nikon Buckmasters II and the Leupold Mark AR MOD are both made for short- to medium-range shooting. The two also have almost identical profiles. However, the Nikon Buckmasters II is selling for just half the price of the Leupold.

The Leupold Mark AR MOD 1 was made entirely in the United States, so if you do not have a smaller budget, the Nikon Buckmasters II is one of the best scopes for the money.

Leupold VX-2 3-9x40mm Riflescope vs. Leupold VX-3i 3.5-10x40mm Riflescope: Which one is better?

These two copes made by Leupold are both good scopes, but one is much better: the VX-3i. The VX-2 does a little bit of everything. It is the kind of hunting scope that you take with you for a regular weekend hunting trip.

The VX-3i, on the other hand, has a little more to offer underneath its matte black exterior. Surely, the VX-3i is more expensive than the VX-2, but that is because it has more features.

If you are looking for a regular, reliable scope, go for the Leupold VX-2. It is the perfect choice if you want something a bit more special that can push the .308 to the test.

Conclusion

The .308 Winchester still holds the title of being the most popular ammunition today, due to its long effective range and its consistent reliability. You need to take advantage of the .308 Winchester’s accuracy and consistent performance by pairing it with a long-range scope that will help you make each and every shot hit its mark.

Unlike other rifles, there is little to no contention about using a scope for .308 rifles on the market, mainly because you can only shoot accurately up to 250 yards using just the iron sights. If you want to accurately shoot targets that are 500, 700, and up to 1000 yards away, then you really need to look for the best scope for .308.
