When it comes to long-range shooting, two cartridges that cannot be ignored are the 6.5 Creedmoor and the venerable 308 Winchester.

Although the 308 Winchester (the commercial variant of the military's 7.62 NATO) has been a staple in the long-range target shooting community since its inception over 70 years ago, the 6.5 Creedmoor simply outperforms it in almost every category when shooting past 500 yards.

In this article I will compare 308 vs. 6.5 Creedmoor in detail, explaining the pros and cons of both cartridges and discussing their respective ballistics data in depth.

Break out your sandbags, bipods, and spotting scopes. We're going to squeeze the trigger and let it fly on long-range shooting!

308 vs. 6.5 Creedmoor: Which Is Better?

Now it’s time we take an objective look at both of these long-range target shooting titans and see which comes out on top!

Recoil

When it comes to recoil, less is better. The less recoil you have, the more accurately you will shoot. For detailed analysis of 6.5 Creedmoor recoil characteristics and how they compare to other cartridges, our comprehensive guide breaks down all the factors that make this cartridge so shooter-friendly.

When you’re shooting long-range matches or just out on the range for an extended period of time, shoulder wear becomes a real problem. Also, the less your rifle pounds your shoulder, the less you will jerk the trigger during firing (so-called “recoil anticipation").

In terms of these two rounds' recoil, there is no contest. The 6.5 Creedmoor has about 30% less free recoil than the 308 Winchester. If you want to learn more about managing 308 recoil and how different rifle weights affect felt recoil, I've assembled a guide to help you with that. After firing both on various occasions, I've found the 6.5 Creedmoor to have less recoil as well.

Winner: 6.5 Creedmoor by a country mile.

Barrel Life

If you are only a hunter and casual target shooter, then you're unlikely to ever "shoot out" a barrel to the point where its accuracy suffers. However, for competitive and long-range target shooters who fire high-precision rifles, barrel wear (which typically first manifests at the throat of the chamber where the bullet enters) is a real problem.

This is one of the 6.5 Creedmoor's few shortfalls. A match-grade 6.5 Creedmoor barrel will typically only last about 2,000 rounds, whereas a 308 match barrel will hold true for around 5,000 rounds.

This disparity is primarily due to the cartridges' similar case capacities. Case capacities for the 6.5 Creedmoor and 308 Winchester are specified at 52.5 grains and 56.0 grains H₂O, respectively. This means that powder charge sizes for both cartridges are also similar. Its larger propellant charge relative to its bore diameter caused the 6.5 Creedmoor's barrel to wear out considerably faster.

Winner: 308 Winchester, hands down.

Hunting

On paper, you would think that the 308 Winchester would be the clear winner in terms of hunting efficacy.

The 308’s wider, heavier .30 caliber bullet should inflict a broader wound channel, cause more blood loss, and penetrate deeper – right?.

Not necessarily. In the field, this is not always the case.

Wound Channel Diameter

You will not see any appreciable difference in wound channels between the 6.5 Creedmoor and the 308 Winchester. Both the 308 and the 6.5 have enough kinetic energy to take down large game from whitetail deer all the way to bull elk without issue.

Variety

The 308 Winchester is available in more varieties, including offerings with heavier bullets up to 180 grains that take down dangerous game, such as black bear, without difficulty. At ranges below 500 yards, the 308 Winchester has higher striking energy than the 6.5 Creedmoor. However, I’m pretty sure the deer in your crosshairs is not going to be able to tell the sub-10% difference between the two rifle cartridges.

Hunting Ammo Availability

One important thing to consider for both the 308 and 6.5 Creedmoor is hunting ammo availability. Although originally developed for competitive shooting, hunting loads like Federal Premium 6.5 Creedmoor have become commonplace on gun store shelves and in sporting goods stores across the nation. The 308 will generally have more hunting ammo varieties available, but 6.5 Creedmoor is getting more popular by the day and is catching up at an alarming rate.

Sectional Density

Another consideration when picking a round for hunting is sectional density (SD). SD is the ratio of bullet diameter compared to its mass. Heavier bullets of any caliber are longer than lighter bullets in the same caliber. That means heavier bullets have a higher SD, and therefore have the capacity for deeper penetration than their lighter counterparts.

Make sure you are fully stocked with Hornady 6.5 Creedmoor hunting ammo for this fall and that you bring home that trophy buck that you have always wanted!

The heaviest 308 Winchester hunting bullets typically weigh a maximum of 180 grains. A 180 grain 308 bullet has an SD of 0.271, whereas a 6.5mm 140 grain bullet has an SD of 0.287.

Its gentler recoil, lower susceptibility to wind drift, lower bullet drop rates, higher sectional density, and flatter trajectory make the 6.5 Creedmoor the ideal hunting round for your new rifle next season.

Winner: 6.5 Creedmoor.

Accuracy

There’s no doubt that the 308 and the 6.5 Creedmoor are extremely accurate rounds. Match-grade loadings with Sierra MatchKing, Hornady ELD-M, or Berger VLD target bullets will give you sub-MOA (minute of angle; 1 MOA = 1" at 100 yards) accuracy if you do your part.

However, the 6.5 Creedmoor’s lower recoil gives most shooters better accuracy results out of the box, with 1/2 – 3/4 MOA groupings being easily attainable.

Winner: 6.5 Creedmoor, by a slight margin.

Long-Range Performance (800+ yards)

There’s no doubt that both rounds are capable of doing very well at long range. Military, law enforcement, and civilian shooters have used 308 at longer ranges for decades. But despite that, everyone seems to be running to the 6.5 Creedmoor. And there's a good reason for that! The 6.5 Creedmoor is specifically designed to outperform the 308 at longer ranges – and it does so in spades.

Looking at the ballistics data tables below, you can see that the 6.5 Creedmoor clearly outperforms the 308 Winchester in every category past 500 yards. The 308 Winchester’s 175 grain loadings typically come close to becoming subsonic at 1,000 yards, whereas the 6.5 Creedmoor is still well above the supersonic threshold at that range. A bullet picks up an accuracy-harming wobble as it transitions from super- to subsonic velocity (a phenomenon known as “transonic destabilization”), hence the 6.5 Creedmoor’s supremacy at longer ranges.

Winner: 6.5 Creedmoor by a long shot.

Reloading

Reloading components for both cartridges are readily available. Furthermore, there are no “tricks” to learn when handloading a 6.5mm cartridge compared to a .30 caliber. Both the 308 Winchester and the 6.5 Creedmoor are a pleasure to handload, with a plethora of bullet and powder options to choose from as you dial in your ideal handload for your favorite long-distance rifle.

The bottom line is that both rifle cartridges are a joy to reload.

Winner: Draw.
