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 5 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,

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
Check Price on OpticsPlanet

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. Leupold VX-3i 3.5-10x40mm Riflescope Leupold VX-3i 3.5-10x40mm Rifle Scope

Check Price on Amazon
Check Price on OpticsPlanet

This .308 optic is a phenomenal choice from Leupold for several reasons. For starters, it can magnify between 5x and 10x and features a 40 mm objective lens. These will allow you to make the most of the .308’s effective range, which is well over 500 yards if you pair it with the right rifle and optic! The lenses are coated for increased light transmission and supreme abrasion resistance; even using the scope in a dusty environment won’t result in scratches accruing over time.

The rest of the scope is also quite durable with an aircraft-grade aluminum body. Each scope is punish-tested before being shipped out to ensure that they perform even under hard recoil. This aspect is important when pairing with a .308 rifle, which can often deliver significant recoil to the operator and their optic.

This scope also comes with a set of windage and elevation adjustment turrets, though these aren’t as detailed as we would like and don’t have indicator marks for easy reference. Despite this drawback, they allow you to make precise ¼ MOA adjustments and are quite dependable even over lots of use. Eye relief between 4.4 inches and 3.6 inches rounds out the scope’s main offerings.

Twilight Max Light management

Like many Leupold scopes, this optic comes with a proprietary light management system. Without getting too technical, this gives you exceptional edge to edge lens clarity and can even offer you an extra 20 minutes of shooting light thanks to extra light collection design. If you plan to use your .308 rifle at the beginning or end of the day (like for hunting animals that are active during these hours), this light management system will be a huge benefit.

The Bottom Line

You should certainly check this rifle optic out if you want an excellent hunting scope for your .308 rifle. The Light Management System and supreme durability over time and through inclement weather make it well worth the asking price.

5. Nikon P-Tactical .308 4-12×40 Riflescope BDC 800

Another great .308 optic comes from Nikon; this variant has magnification settings between 4x and 12x with a 40 mm objective lens. This allows it to capture adequate light for both hunting and tactical situations and enables you to make the most of your .308 rifle’s range upwards of 500 yards. As the name suggests, this is an excellent tactical scope thanks to the multicoated optics that provide fantastic light transmission.

This scope also comes with precise and ergonomic turrets. These are spring-loaded and can easily be reset to zero after sighting. This allows you to make easy references in the field and adjust for evolving tactical scenarios. They’re easily marked, too, for your convenience.

The scope is quite durable in inclement weather and even works in fog or after being dropped. The shockproof construction will shrug off even heavy recoil, like the kind you can expect from some .308 rifles. It also comes with excellent eye relief between 3 and 4 inches depending on your magnification setting, which should protect your eye from getting bruised even if you pair this optic with a hard-kicking .308 rifle.

BDC 800 Reticle

You’ll definitely enjoy the BDC 800 reticle, which allows you to compensate for bullet drop at farther distances up to about 800 yards. Hitting distant targets with your .308 rifle has never been easier. Even better, this particular type of BDC reticle has open circles and other hash marks, which means that the reticle never blocks your line of sight to your target. 

The Bottom Line

All in all, this is a fantastic tactical or hunting optic that’s a phenomenal choice to pair with any .308 rifle. It’s durable, easy to use at far ranges, and swaps between magnification settings for windage and elevation values with quick adjustments.

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