There’s more to your grandpa’s old hunting rifle than you think. Hunters around the world from Africa to Europe sing of its praises. It’s the most popular short-action, big-game hunting cartridge and it’s made right here in the USA.

For over 70 years, Winchester continues to proudly deliver the power of the battlefield to your hands. The same rifle that won WWI battles now brings dinner to your table and wins bets at the shooting range.

Civilians, military, police, and even NATO all love the .308 because:

  • It’s effective within its parameters
  • Aerodynamic shooting
  • Economic powder consumption
  • Utilizes all but the heaviest .308” bullets
  • Hefty, comfortable weight
  • Multi-use capabilities in several settings

Over time it has evolved into models with lighter recoil and improved downrange energy, making it applicable to metallic silhouette shooting. There’s absolutely nothing it can’t do and is all around is a machine that gets the job done.

It’s the rifle that every other rifle strives to be. In fact, it has been the inspiration for other popular hunting rifles. Although they are great in their own right, they aren’t even close to the same level.

Let’s look closer at what it can really do in a pair of trained and willing hands.   

Going the Distance: Maximize your Shooting Range

Out-of-the-box, a .308 Winchester can shoot accurately up to 200 yards with less than 1 MOA. 

After 200 yards, bullet drop increases and velocity decreases quickly. Many .308 users try to push the limitations of its range, expecting more than it can deliver alone. If you want to make that a reality, a .308 scope is a necessity in order to raise the bar. The .308 can shoot up to 800 yards and even further with the right scope and enough training and practice.

A Quick Guide to Distance: How Far will Your Bullet Go?

For an out-of-the-box 308 with a 28-in barrel, keep these rough measurements in mind:

  • Long Range: 350 yards and above
  • Medium Range: 150 – 349 yards
  • Close Range: Under 150 yards

When you hunt or go to target practice, how far away are your targets? Are you an up close and personal shot or do you get a thrill from stalking at long-distance? Since it will make a difference in the type of scope that you buy, you should pay attention to magnification.

Having the best scope for 308 rifles with the appropriate power will make all the difference.

What magnification do you need?

The .308 is a powerhouse that shoots farther than many other rifles can even think about shooting. However, just because you have a .308 doesn’t mean that you are required to do long-distance shooting.

If you do, longer shots will require higher magnification. What is magnification and what does it mean? Check out our quick guide here to understand how lens measurements and magnifications work.

Which one of these works best for your normal situation?

  • Long Range (350 yards and above)
    This is where you’ll really put the power of your rifle to the test. When you want to push far, far beyond these 350 yards, you’ll need .308 optics to get you there. If you’re ready to go for the long haul, we suggest 10x magnification and above. The smaller the target, the more magnification you will need.
  • Medium Range (150 – 350 yards)
    Since the .308 rifle is made to take down medium-to-large size game, this is your ideal distance. Why? Shooting from too far away can result in painful injury to the animal instead of a quick, clean kill. Also, a stressful death will only taint the flavor of the meat, negating your efforts. If you want to retain your position as an ethical hunter, you’ll want between 6 – 9x magnifications.
  • Close Range (Up to 150 yards)
    Higher magnification at close range will only blur your vision. If you want an accurate shot under 150 yards, you’ll use a lower magnification. We suggest 1 – 6x power.

The best scope for 308 rifles will always be one that compliments your shooting style. If you’re proud of your long-range skills, show them off with a scope that has high magnification. Otherwise, you might want to invest in a wide variable range to quickly adjust up and down.

Either way, your scope should match your personality. Don’t let anyone tell you otherwise.

Finding Your Next Scope

Read on to find out why we think these 4 scopes are the best for the .308.

1. Vortex Optics Crossfire II 6-24x50mm

Vortex Optics Crossfire II 6-24x50 AO, Second Focal Plane Riflescope - Dead-Hold BDC Reticle (MOA)

Check Price on Amazon

When loyal Vortex fans compare this budget scope to its $1000 counterpart, you know you’re getting the best quality. With a magnification range maxing out at 24x power, you can shoot well up to 1000 yard or more. Several factors make it an ideal medium to long-range scope for hunting or tactical shooting for your .308.

Anti-reflective coatings on its glass surfaces increase light transmission to near perfect. Glare is minimal in harsh sun and you can still see clearly in low light environments. It offers an above-average eye relief of 4 inches and a fast-focus eyepiece to keep you moving. For even greater agility in the field, the resettable MOA turrets have your back in high-intensity situations.

Dead-Hold BDC Reticle

The infamous Dead-Hold reticle takes the guesswork away from hold-over and windage. In this particular scope, it’s dead-on accurate up to 18x magnification. It uses the second focal plane design that maintains an ideal size through each adjustment. That means all you have to do is line up your shot and pull. It’s even easier with Vortex’s Long Range Ballistics Calculator (LRBC) which allows you to custom match yardage to drop hash marks.

The Bottom Line

If close range isn’t your scene, this is a great choice in our opinion. You will be hard-pressed to find a better scope for .308  at that price. It’s as close as you can get to a tournament-quality scope without paying tournament-quality money. Although we tried to find some negative aspects for a fair review, this scope just brings nothing but good news!

2. Athlon Optics, Argos BTR, Riflescope, 6-24 x 50 MIL Reticle

Athlon Optics , Argos BTR, Riflescope, 6-24 x 50 First Focal Plane (FFP) 30 mm Tube, Illuminated APMR MIL Reticle,

Check Price on Amazon

From the maker of affordable yet high-quality binoculars and riflescopes, we have the Argos BTR 6-24 x 50 MIL Reticle scope. If you’re looking for a long-range riflescope, the Argos BTR must be on your shopping list. What makes this riflescope stand out is the excellent optics, which comes at a very affordable price!  The Advanced Fully Multi-Coated lens produces crisp and clear images even under dimly lit or foggy conditions.

When it comes to the build quality, this riflescope passes the test with flying colors. It’s crafted out of 6061T6 aircraft grade aluminum. And that makes it one of the most durable scopes for the price.

But great build quality and durability don’t define a great riflescope. So, how good is the accuracy over long distances? Well, when you pair up the excellent optics with the 6x to 24x zoom, you have a deadly accurate long-range scope. You can even manage 1000-yard shots reliably with the Argos BTR.

However, not everything is sunshine and rainbows with this product. One of the biggest drawbacks is the relatively shorter eye relief of 3.3 inches.

Illuminated Reticle

This is surely one of the most underrated features of the Argos BTR. The illuminated reticle makes it so much easier to take accurate shots in dimly lit situations. And when you couple that with the crisp and clear optics, this riflescope performs admirably under dark conditions.

The Bottom Line

If you’re looking for an affordable long-range riflescope, which does everything almost as good as the more premium competitors, then the Argos BTR should surely be on your radar. Just don’t expect it to outperform the high-end scopes costing 4 figures.

3. Vortex Optics Diamondback 4-12x40mm SFPVortex Optics Diamondback 4-12x40 Second Focal Plane Riflescope - Dead-Hold BDC Reticle (MOA)

Check Price on Amazon

This Vortex riflescope can switch between 4x and 12x zoom levels. The scope has a 40 mm objective lens that’s wide enough to give you a good field of view no matter which magnification power you’re currently on. It’s not big enough to ruin the balance of your rifle, too, or require extra mounting options due to size.

In fact, switching between magnification settings is easier than ever, thanks to the precision glide erector system. This system helps ensure that every time you switch magnification powers is smooth and perfect without jamming.

BDC Reticle

As you can tell from the name, this Vortex scope has a reticle located on the second focal plane. It’s a dead-hold BDC variety. This means that the reticle comes equipped with hash marks under its vertical line. You can use these hash marks to estimate your bullet drop across distances. This effectively helps you be more accurate at long ranges, even with elevation differences between you and your target.

Estimating windage holdover is also a breeze since there are hash marks on the horizontal plane, as well. Since this is a second focal plane reticle, it won’t change sizes no matter which magnification setting you decide on.

The lenses are fully multicoated to give you bright sight pictures and high color contrast images, even in low-light conditions. The scope is also equipped with a fast-focus eyepiece that helps you focus on the reticle quickly.

The scope makes use of precision adjustment turrets. These turrets are made of metal for extra durability and consistency. As far as durability goes, the scope is made of a single piece of aluminum and has a hard-anodized finish. This anodized finish prevents the scope from glaring in sunlight, possibly preserving your hidden location during a hunt. It also resists rust damage over time.

The Bottom Line

This scope is excellent for making snappy shots at all sorts of ranges. Switching between zoom levels is quick, and you can make use of the fast-focus eyepiece to land shots at a moment’s notice.

4. SWFA SS 3-15x42mm Tactical Rifle Scope SWFA SS 3-15x42 Tactical Rifle Scope FFP Mil Quad Reticle 1/10 Mil Adjustments SS315X42MQ

Check Price on Amazon

This SWFA rifle scope can switch between 3x and 15x power depending on your needs. It’s equipped with a 42 mm objective lens that’s balanced between light collection potential and size. It’s not large enough to throw the balance off many rifles.

Great Lenses

The lenses are fully multicoated to improve light transmission and boost color contrast. The coatings ensure that you’ll be getting the best sight picture possible even as your light conditions change throughout the day.

The reticle is located on the first focal plane and is a Mil-Quad type. It’ll switch sizes as you move between magnification levels, but it’s holdover points will remain the same size relative to your target the entire time. The reticle is quite accurate and easy to use but lacks any sort of illumination. So it’s not the best scope to use during the brightest part of the day if you’re out in the open.

The scope provides up to 4.2 inches of eye relief; this is plenty for most folks, even if recoil is higher than you anticipated. A left-hand side parallax adjustment turret complements the windage and elevation adjustment turrets. All of these rely on tactile clicks to let you know when you’ve made a change. It’s easy to adjust these variables without taking your eye from the scope as a result. 

The scope is also totally waterproof, shockproof, and fog proof. It has a matte finish that eliminates the possibility of sun glare. This functionality can help you stay hidden in the brush when certain animals might be watching for your presence.

The Bottom Line

Overall, this scope is versatile and well-built but lacks an illuminated reticle to make it ideal for bright daylight shooting. Still, if your hunting tends to take place during the dusk or dawn, few scopes can match the sight picture provided here.

This scope would also be an excellent choice for an M1A and for Remington 700 chambered in .308.
