6.5 Creedmoor vs 308 Winchester Debate Settled

The rapid ascent of the 6.5 Creedmoor in recent years has ignited the 6.5 Creedmoor vs 308 debate among hunters. Here’s what you need to know about these two cartridges.

I think most shooters agree that the .308 Winchester and 6.5 Creedmoor are both fantastic cartridges for competition shooting. While the .308 Winchester has been around for a long time and also has a well deserved reputation as an effective cartridge for hunting a variety of game, many hunters are skeptical of the capabilities of the comparatively new 6.5 Creedmoor as a hunting cartridge. So what’s the real deal with hunting with the 6.5 Creedmoor vs 308 Winchester?

Unfortunately, there is a lot of marketing hype as well as a few genuine misunderstandings regarding the capabilities of the 6.5 Creedmoor that complicate this discussion. For that reason, it’s easy to understand how many hunters get confused about the strengths and weaknesses of the 6.5 Creedmoor and the .308 Winchester as hunting cartridges.

In this article, I’m going to discuss the pros and cons of the 6.5 Creedmoor vs 308 Winchester so you can make an informed decision on which one is right for your particular situation.

6.5 Creedmoor vs 308: History

The story of the .308 Winchester begins right after World War II when American military leaders decided to replace the venerable .30-06 Springfield cartridge and M-1 Garand rifle. Though the cartridge and rifle performed admirably in the hands of American GIs, military leaders wanted a new rifle with a detachable magazine that was capable of fully automatic fire similar to the Soviet AK-47 or the German StG-44.

After several years of development and testing, the US Army replaced the M-1 Garand with the M-14 rifle chambered in the new 7.62x51mm cartridge. Like the .30-06, the new cartridge also fired a .308″ bullet. However, due to advances in powder technology since the introduction of the .30-06, the 7.62x51mm cartridge used a shorter case (51mm vs 63mm), but had virtually the same ballistics (a 147 gr bullet at 2,750 fps vs a 150 gr bullet at 2,700 fps) as the .30-06.

If you’d like to read a more detailed discussion on the 7.62x51mm cartridge and how it compares to the .30-06 Springfield, read this article:

308 vs 30-06 vs 300 Win Mag: Which Cartridge Should You Be Hunting With?

Around that same time, the leadership at Winchester saw a lot of potential for commercial success in the civilian hunting and shooting markets with the new 7.62x51mm cartridge and rolled out the extremely similar .308 Winchester. In short, the .308 Winchester could do virtually everything the .30-06 Springfield could do with up to a 180 grain bullet, but the new cartridge could fit in a short action rifle and had a slight edge in accuracy over the .30-06.

As a result, the popularity of the new .308 Winchester cartridge gradually increased as hunters and shooters realized the inherent accuracy, efficiency, and power of the cartridge.

For these reasons, the .308 Winchester was one of the most popular short-action rifle cartridges for many decades and eventually became the standard against which other short-action cartridges were judged. Indeed, many of the other popular short-action cartridges (like the .243 Winchester, .260 Remington, and 7mm-08 Remington) were descended from the .308 Winchester.

Though the .308 Winchester was a very popular cartridge for high power rifle competition shooting for many years, Dave Emary and Dennis DeMille of Hornady Manufacturing saw an opportunity to build a new cartridge that outperformed the .308 Winchester in the early 2000s. Specifically, they wanted to build an ideal long range shooting cartridge that was just as accurate as the .308 at long distance, but with less recoil, less wind drift, and a flatter trajectory.

With that in mind, they modified a .30 Thompson Center (.30 TC) case to shoot .264″ bullets. The cartridge had a relatively large case capacity optimized for use with 4350 class propellants. They also built the accompanying rifle with a relatively fast 1:8″ rifling twist rate. When all was said and done, the new cartridge could accommodate long, heavy, high ballistic coefficient (BC) bullets in a short action magazine without intruding into the powder column.

Emary and DeMille were quite successful in their goal of building the ideal competition shooting cartridge in the 6.5 Creedmoor (sometimes misspelled Creedmore). Named in honor of the Creedmoor Matches (which interestingly is now the site of a psychiatric hospital on Long Island), the 6.5 Creedmoor does not have eye popping ballistics, but it has minimal recoil, is very accurate, and uses high BC bullets that retain energy and resist wind drift exceptionally well.

For those reasons, the cartridge has seen a great deal of success in the hands of competition shooters and has recently made the jump into the mainstream hunting community.

6.5 Creedmoor vs 308: Cartridge Sizes

You can see some of the similarities and differences between the 6.5 Creedmoor and .308 Winchester cartridges in the photo below. Both cartridges are used in short action-rifles, so they have very similar external dimensions.

The .308 Winchester has a slightly longer same case length (1.92″ vs 2.015″), but the 6.5 Creedmoor has a little bit longer overall length (2.825″ vs 2.81″).

6.5 creedmoor vs 308 featured

The 6.5 Creedmoor has a sharper shoulder angle (30 degrees vs 20 degrees for the 308) and a slightly less tapered case than the .308. Those traits allow the Creedmoor to use very long, high BC bullets without sacrificing case capacity. Both cartridges have the same .473″ rim diameter, can hold almost the same amount of powder, and have the same SAAMI maximum average pressure of 62,000psi.

Note: while the case capacity figures listed below do give a good indication of the differences between the two cartridges, exact case capacities vary slightly according to the brand of brass used.

6.5 creedmoor vs 308 size and pressure

6.5 Creedmoor vs 308 Ballistics

The table below compares 120gr Nosler E-Tip (.497 BC) and 143gr Hornady ELD-X (.625 BC) loads in 6.5 Creedmoor to 150gr Nosler E-Tip (.469 BC) and 178gr Hornady ELD-X (.552 BC) loads in .308 Winchester. This data is for Hornady and Nosler factory ammo using a 24 inch barrel and a 200 yard zero.

6.5 creedmoor vs 308 trajectory

As you can see, the two cartridges have a very similar trajectory out to 300 yards. However, the 6.5 Creedmoor has a flatter trajectory overall, particularly at 400 and 500 yards. This due to the fact that the 6.5 Creedmoor fires a lighter bullet with a higher ballistic coefficient at a higher muzzle velocity than the comparable .308 Winchester load. Specifically, the Nosler E-Tip and ELD-X bullets from the Creedmoor have less bullet drop and hit 4.6″ and 6.5″ higher respectively than the same bullets from the .308 at 500 yards.

The .308 Winchester does start off with a big advantage in kinetic energy of 345 and 357 foot pounds of energy at the muzzle with the E-Tip and ELD-X. By 500 yards though, the ballistically superior 6.5mm bullets help narrow that gap down to 108 foot pounds with the E-Tip and just 38 foot pounds of energy with the ELD-X.

The chart below compares how much a 10 mile per hour crosswind impacts those same four loads out to 500 yards. 

6.5 creedmoor vs 308 wind

The superior ballistic coefficient of the 6.5 Creedmoor helps give the cartridge a moderate advantage over the .308 Winchester in terms of wind drift. At 500 yards, the .308 Winchester E-Tip and ELD-X loads drift 2.3″ and 3.3″ more respectively than the comparable 6.5 loads.

However, the advantage isn’t as pronounced at 500 yards as it is at longer ranges. Since this article is focused on the performance of these two cartridges for hunting, I didn’t include any wind drift figures past 500 yards in the table above.

Just to give you an idea how much the 6.5 Creedmoor advantage in wind drift grows during long range target shooting though, the 6.5 Creedmoor ELD-X load drifts 70.1″ at 1,000 yards. This is nearly 1.5 feet less than the 87.4″ of wind drift for the .308 Winchester ELD-X at the same range.

Additionally, though the .308 Winchester is a relatively mild recoiling cartridge itself (especially compared to other .30 caliber cartridges like the .30-06 and .300 Win Mag), the 6.5 Creedmoor has a big advantage in this area as well.

picture of 6.5 creedmoor vs 308 winchester recoil

For example, when fired from a Ruger Hawkeye Predator rifle, the 178gr ELD-X from the .308 Winchester has about 30% more recoil than the 143gr ELD-X 6.5 Creedmoor load.

Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges.Most shooters should be able to handle the recoil of both cartridges, but the 6.5 Creedmoor has a pretty significant edge in this respect.

Don’t underestimate the impact that recoil has on the ability of a person to shoot accurately either. Regardless of how well a given person handles recoil, all other things being equal, they will absolutely shoot better with a milder recoil.

The 6.5 Creedmoor also has an advantage when it comes to bullet selection. Since it was originally built for competition shooting, the cartridge was specifically designed to use the longest and heaviest 6.5mm (.264″) bullets available. This is why most 6.5 Creedmoor rifles have a fast 1:8″ rifling twist rate. The cartridge most often utilizes bullet weights in the 95-160 grain range, with 120, 129, 140, and 143gr bullets being the most common.

As we covered earlier, those longer and heavier .264″ bullets have a higher ballistic coefficient than the most common bullets used in the .308 Winchester. They also have a higher sectional density (SD).

Sectional density (SD) is a measure of the ratio of the diameter of a projectile to its mass. All other things equal, a heavier projectile of a given caliber will be longer and therefore have a higher sectional density and consequently penetrate deeper than projectiles with a lower mass and sectional density.

For instance, it’s very uncommon to find .308 loads using bullets heavier than 180 grains.

A 180 grain .308″ bullet has a sectional density of .271 and a 168 grain .308″ bullet only has a sectional density of .253. However, a .264″ 140 grain bullet has a sectional density of .287 and a 143 grain .264″ bullet has a sectional density of .293, which compares favorably to the most common .308″ bullets.

That being said, the .308 Winchester uses larger diameter bullets and consequently has about 36% more frontal surface area (also known as cross sectional area) than the 6.5 Creedmoor (.0745 vs .0547 square inches). All other things being equal, a bigger bullet will make a bigger hole, cause more tissue damage, and result in more blood loss.

Both cartridges have a long and distinguished history in the competition shooting realm and both cartridges are extremely accurate (offering sub-MOA performance) in the right hands at typical hunting ranges.

However, the 6.5 Creedmoor most likely has a slight advantage in terms of accuracy as well.

This is for several reasons, but the fact that the 6.5 Creedmoor uses a much more modern overall cartridge design than the 308 Winchester is an important factor here.

John Snow wrote a fantastic article on this subject for Outdoor Life, but long story short, companies designing new cartridges these days typically employ more modern cartridge design principles that incorporate best practices obtained from competition and benchrest shooters to obtain the best possible accuracy.

Cartridges designed using these principles use faster twist rates to stabilize heavy, high BC bullets, have cases with a long enough neck to support those longer, high BC bullets, can seat those long, high BC bullets to the SAAMI specified maximum overall length without intruding into the powder column, employ minimal body taper, headspace off sharp shoulders, and have a chamber design with a snug throat.

Taken together, these design principles result in cartridges with a very high degree of accuracy potential, especially at extended range. 

Like I mentioned earlier, the 6.5 Creedmoor design incorporates all of those principles and this likely explains why the cartridge has such an excellent reputation for accuracy. 

Let’s drill down into the chamber design aspect of things in more detail.

The throat is the smooth portion of a rifle barrel closest to the cartridge. Having a more snug throat diameter means there’s less room for the bullet to yaw upon firing before engaging the rifling, which can help enhance accuracy.

Well, the 6.5 Creedmoor has a throat diameter just .0005″ larger than the bullet diameter. This is a significant improvement over cartridges like 308 Winchester (.002″).

Additionally, the 6.5 Creedmoor also has a steeper 30 degree shoulder (compared to the 20 degree shoulder of the 308 Winchester) for more precise and more consistent headspacing, has a faster SAAMI spec rifling twist, and has a long enough case neck and has ample head height to use those long, heavy, high BC bullets I keep talking about.

Taken together, all of these factors result in better accuracy potential for the 6.5 Creedmoor, especially with long, heavy, high BC bullets.

That’s not to say that all 6.5 Creedmoor rifles are accurate with all types of ammunition.

I’m also not saying the 308 Winchester isn’t capable of excellent accuracy at times either.

The exact details will vary on the exact rifle, ammunition, and shooter in question. 

However, I will say the 6.5 Creedmoor has the best potential for accuracy of the two cartridges on average using factory rifles and ammunition.

Plus, since it was specifically designed as a competition shooting cartridge and utilizes .264″ bullets, there is a bigger selection of high BC and high SD match grade hunting bullets available for the cartridge. 

That’s not to say that the .308 Winchester isn’t accurate or that there aren’t a bunch of good quality bullets available for it. It’s just that the overall design of the 6.5 Creedmoor gives that cartridge an edge over the .308 Winchester.

The United States Special Operations Command (USSOCOM) recently conducted a study comparing the 6.5 Creedmoor, .260 Remington, and .308 Winchester cartridges and they came to a similar conclusion. Compared to the current M118 Special Ball Long Range .308 Winchester load (a 175gr Sierra MatchKing Boattail Hollow Point) currently used by special operations snipers, the 6.5 Creedmoor had less recoil, doubled hit probability at 1,000 meters, had a 33% longer effective range, retained 30% more energy at 1,000 meters, and had 40% less wind drift at 1,000 meters.

So where do we stand overall with both cartridges?

6.5 Creedmoor vs .308 Winchester

The 6.5 Creedmoor shoots smaller diameter and generally more aerodynamic bullets than the .308 Winchester. Therefore, the 6.5 Creedmoor has a slightly flatter trajectory, a little less wind drift, and less recoil. However, the .308 has a lot more frontal surface area and carries more energy downrange.

With a flatter trajectory and less wind drift, the 6.5 Creedmoor does have a definite, though not gigantic, advantage over the .308 Winchester in external ballistics at typical hunting ranges. This makes the cartridge more forgiving of range or wind estimation errors than the .308 Winchester. It also has less recoil than the .308 Winchester as well as a large selection of high BC match grade hunting bullets.

All things considered, the 6.5 Creedmoor is a cartridge that helps maximize the shooting abilities and maximum effective range of the hunter to a greater extent than the .308 Winchester. Proper shot placement is extremely important when it comes to ethically taking game and the aforementioned strengths of the 6.5 Creedmoor all facilitate precise shot placement. Finally, the high SD bullets used by the 6.5 Creedmoor also assist with penetration to help the cartridge “punch above its weight” in a manner similar to the 7x57mm or 9.3x62mm Mauser cartridges.

On the other hand, the .308 carries more energy downrange than the Creedmoor and has a big advantage when it comes to frontal surface area. Those traits give hunters a tiny bit more room for error in shot placement when compared to the 6.5 Creedmoor.

It might seem like I’m splitting hairs here when talking about the strengths and weaknesses of the two cartridges. That’s absolutely true to a certain degree.

While they certainly have different advantages, both cartridges are very accurate, relatively flat shooting, and hit hard enough for use on a variety of game out to several hundred yards. Regardless of whether you’re using a 6.5 Creedmoor or a .308 Winchester, no pronghorn, deer, or elk will go far if you put a well constructed bullet into the vitals.

308 vs 6.5 Creedmoor Barrel Life

While the two cartridges have a very similar case capacity, throat erosion occurs faster with the 6.5 Creedmoor because it uses a smaller diameter barrel. Simply put, burning the same amount of powder in a smaller space will result in shorter barrel life.

This means that, in general, the 6.5 Creedmoor will simply wear out barrels faster than the .308 Winchester will. Exactly how fast that occurs depends on a number of factors like the quality of the barrel, the exact ammunition used, etc.

For serious target shooters, this is a concern. However, the good news for hunters is that typical 6.5 Creedmoor barrel life of 2,000-3,000 rounds is more than enough to last for many, many years of hunting with no issues at all.

So, there is basically no practical difference in 6.5 Creedmoor vs 308 Winchester barrel life as far as most hunters are concerned.

6.5 Creedmoor vs 308: Ammunition Selection

The .308 Winchester is extremely popular among hunters and shooters in the United States and consistently ranks as one of the best selling cartridges in the country. The 6.5 Creedmoor is no slouch in this regard, but it still can’t hold a candle to the .308 in terms of widespread use. Even so, the cartridge seems to be steadily growing in popularity, but only time will tell if it becomes as popular or widespread as the .308 though.

The big ammunition manufacturers like Barnes, Berger, Black Hills, Federal Premium, Hornady, HSM, Norma, Nosler, PPU Remington, Sellier & Bellot, Swift, and Winchester all produce a number of high quality 6.5 Creedmoor, and .308 Win factory ammunition suitable for hunting.

Most of the major bullet styles designed for hunting are available in those cartridges as well like the Barnes TTSX, the Berger VLD, the Hornady ELD-X, GMX, InterLock, SST, and V Max, the Nosler AccuBond, Ballistic Tip, E-Tip, and Partition, the Remington Core Lokt, and the Winchester Power Point.

There’s also a gigantic selection of target shooting bullets for both cartridges as well including (but not limited to) the Hornady A-Max and Sierra MatchKing. Heck, it’s even possible to get varmint hunting bullets for both cartridges.

Prices and availability vary from region to region, but ammunition for both cartridges is very common. The .308 Winchester is a much easier to find and a little less expensive than the 6.5 Creedmoor though.

Additionally, there is also still a large quantity of full metal jacket military surplus ammo in 7.62x51mm NATO out there. This ammunition isn’t as inexpensive or easy to find as it used to be, but there are still good deals to be had if you look hard enough. Surplus FMJ ammo is ideal for practice, but those aren’t great (or legal) hunting rounds in most states though.

Reloading components for all both cartridges are also widely available so making custom handloads isn’t too difficult for either cartridge. .308 Winchester and 6.5 Creedmoor brass are both widely available.

Since the .308 and 6.5 have the same bullet diameter as other popular .30 caliber and 6.5mm cartridges like the 6.5x47mm Lapua, 6.5 PRC, .264 Win Mag, .30-06 Springfield, .300 Win Mag, .300 Remington Ultra Magnum, .300 PRC, and 300 WSM, there are plenty of .264″, and .308″ bullets of various weights and styles to choose from.

Along with the massive number of ammunition choices available in these cartridges, there are lots of quality rifles manufactured in 6.5 Creedmoor and .308 Winchester. Just like with ammunition though, .308 rifles are the most common (though 6.5 Creedmoor rifles are by no means rare).

To an even greater degree than most other gun manufacturers, Ruger has really gotten behind the 6.5 Creedmoor and offers their American, FTW Hunter, Hawkeye Long Range Target, Number 1, Precision, and Scout Rifles in both cartridges. Additionally, the Remington Model 700, Browning X-Bolt, Mossberg Patriot, Nosler M48, Savage Avis, Weatherby Vanguard, and the Winchester Model 70 are all bolt-action rifles available in 6.5 Creedmoor and .308 Winchester.

The .308 Winchester is also pretty common in semi-automatic sporting rifles like the AR-10 and M1A as well as military surplus rifles like the FN-FAL. The 6.5 Creedmoor is available in the AR-10 platform, but there aren’t many other semi-auto rifles available in that cartridge.

Though there are some exceptions, since both are short-action cartridges, rifles of the same model chambered in each cartridge are virtually identical to each other. Depending on the exact model, 22″ and 24″ barrels are very common for both cartridges.

It’s even possible to get a handgun in either .308 Winchester or 6.5 Creedmoor these days as well.

6.5 Creedmoor vs 308: Which Is Right For You?

The 6.5 Creedmoor and .308 Winchester are both flat shooting cartridges well suited for hunting thin skinned, small to medium sized animals like blacktail deer, mule deer, whitetail deer, fallow deer, or pronghorn.

While they are excellent choices for hunting deer sized game, these cartridges, but particularly the .308 Winchester, are also suitable for bigger game under the right conditions. When using well constructed bullets and with proper shot placement, they will absolutely work for elk and even moose hunting at reasonable ranges. They’re also acceptable choices for hunting many species of African plains game.

I’d personally lean strongly towards the 308 Winchester over the 6.5 Creedmoor for hunting bigger game. Don’t let anyone tell you that the 6.5 Creedmoor is too small for moose or elk though. Scandinavian hunters have taken untold numbers of moose with the 6.5x55mm Swedish over the past century. That cartridge has ballistics very similar to the 6.5 Creedmoor and is a good example of what a high sectional density bullet will do on really big game animals with excellent shot placement.

So yes, you can hunt elk with the 6.5 Creedmoor, but you need to be aware of a couple of things before you go down that road.

To that end, I recorded an entire podcast episode on elk hunting with the 6.5 Creedmoor with someone who has cleanly taken elk with the cartridge. Our discussion does a great job of covering the pros and cons of the 6.5 Creedmoor for elk hunting and anyone planning on going elk hunting in the future should definitely listen to this interview.

That said, the 6.5 Creedmoor and .308 Winchester are definitely in a different league from heavy hitting cartridges like the 7mm Rem Mag and .300 Win Mag when it comes to hunting really tough, big, or dangerous game.

Do you primarily hunt medium sized game like deer, feral hogs, or black bear at ranges within 200 yards? Both cartridges will absolutely get the job done if you do your part and there isn’t much of a difference between them ballistically inside of 300 yards. Go with the .308 Winchester if you want the cheapest or easiest to find deer hunting ammo.

Are you interested in the better cartridge for hunting game like mule deer or pronghorn in open country where you might need to take a shot at several hundred yards? Both will also work in this role, but the 6.5 Creedmoor has a flatter trajectory, will drift less in the wind, and still carries enough energy out to 400-500 yards to cleanly take deer sized game without any issues.

Do you prefer to use a semi-automatic rifle for hunting or want a battle rifle for personal defense? Go with the .308 Winchester as there are many more quality rifles available in this cartridge than the 6.5 Creedmoor.

Are you sensitive to recoil? Go with the 6.5 Creedmoor. This cartridge is especially well suited to new, small framed, and or recoil shy hunters. Indeed, a good rifle chambered in 6.5 Creedmoor is a great gift for a hunter who is just getting started.

Are you a serious long range shooter searching for the cartridge best suited for target shooting out to 1,200 yds or so in a precision rifle? Again, go with the 6.5 Creedmoor, which really stands head and shoulders above the .308 Winchester for long range precision shooting.

Do you want a cartridge well suited for elk, moose, caribou, kudu, eland, or red stag hunting? Especially when using heavier bullets, the .308 Winchester wins hands down here due to the big advantage the cartridge has in in frontal surface area as well as energy under 200 yards.

Like I’ve said many times before, the 6.5 Creedmoor and the .308 Winchester are both excellent rifle cartridges. While the differences between them (6.5 Creedmoor vs 308 Winchester) are pretty big in some areas, one isn’t really “better” than the other on the whole. Carefully evaluate your needs as a hunter based upon the circumstances you foresee using the cartridge in, get a good hunting rifle chambered in the cartridge you select, learn to shoot it well, use quality bullets, and you’ll be all set for most hunting situations.

55 thoughts on “6.5 Creedmoor vs 308 Winchester Debate Settled”

  1. This is fun.
    The 6.5 Creedmoor has rendered both itself and the 308 as sub-par (not obsolete mind you).

    For decades the 308 held some regard because though it lacked the knock-down power of the 30-06 at closer ranges, it was (generally speaking) more accurate.

    Now we have the new champion, the 6.5 Creedmoor, that is more accurate at longer ranges than the 308. Alas 6.5 Creedmoor delivers far less knock down power to be considered a replacement for the 30-06 for larger game (or the 308 for that matter) depending on the range.

    I’m not sure why a comparison between the two was in order … or why there was a “so-called” debate in the first place.

    The 6.5 Creedmoor is a flat-shooting round.
    The 308 is a harder hitting round at closer ranges.

    There are a number of rounds on each end of the caliber spectrum that outperform both of them.
    So what.

    The 338 Lapua Magnum outperforms most everything.
    If ya want a good long range rifle chaos the 338 Lapua.

      • The difference is so miniscule that anyone arguing over this is just a moron. And apparently the writer has no idea what muzzle energy is. Because apparently it means something different to the rest of us.
        The .308 Winchester does start off with a big advantage in kinetic energy of 345 and 357 foot pounds of energy at the muzzle
        345 ft lbs at the muzzle? Did he copy and paste a 9mm?

        • Thank you very much for your very kind & thoughtful comment Charles. When I say the 308 Winchester has a “big advantage in kinetic energy of 345 and 357 foot pounds of energy at the muzzle with the E-Tip and ELD-X”, most people would take that to mean that the 308 has 345 and 357 foot pounds MORE energy than the 6.5 Creedmoor with those two specific bullets. You could say that’s a “minuscule” difference if you’d like, but others would say a ~15% advantage in favor of the 308 is more significant.

    • There’s a difference in shooting a .338 Lapua Magnum which most people don’t consider, cost and physical abuse. I shot a Sako TRG-42 in competition for years and one thing was certain, it may be a powerhouse, but, if you don’t shoot it often you won’t be any good with it. Barrel life on average was anywhere between 750 and 950 rounds, dependent on bullet weight and type of powder being used. In three shooting seasons I consumed five barrels and several thousands of dollars in ammunition which I reloaded myself. If you hunt with a .338 Lapua Mag you are usually just a one shot wonder. I know very few hunters that can actually “use” a .338 Lapua Mag to the potential it’s ballistics offer. Can that elk be downed with a 30-06, sure, but why use a 30-06 when you can take field artillery with you and brag about shooting an elk with a .338 Lapua Magnum. Did I ever hunt with a .338 Lapua, sure I did, killed an elk at over 1500 yards with it. Why did I take that shot, because I could, knew the ballistics and the gun, and knew what to expect when the loud pedal was pressed. Now, would I take a .338 Lapua with me now to hunt, nope, been off the gun and cartridge too long and therein lies the problem. You don’t use it, you loose it. That sucker burns anywhere between 89 and 95 grains of powder pushing a 300 grain Sierra MatchKing, not even a little pleasant. But you know what, took a 6.5 Creedy with me last year and dropped an elk like it was pole axed at about 470 yards with an ear shot. Only difference was I wasn’t suffering from concussion induced mental trauma and my synthetic shoulder complained not one bit. Yes, we can all balls up on a caliber to hunt whatever it is you think you need to vaporize with a .338 Lapua Mag, but sometimes it’s not about quantity and it’s just about the quality. For me, the monster magnums are behind me. I kinda like the 6.5 Creedy, easy to shoot, easy to load for, and laser beam accurate. Give it a try and you just might like it!

      • 1500 yard elk shot, only a fool would believe that. The 6.5 Ceedmor is a good cartridge but at REALISTIC hunting yardage, say up to 300 yards,
        The.308 and even better 30/06 deliver much better ballistics.

      • 308 150 grn psp at 2,820 fps
        6.5 143 grn at 2,730 fps
        260 rem 143 grn at 2,730 fps
        None of the above are a laser
        Only the 308 can utilize a 180 or 210 grn bullet. For clean harvest.
        And NO ONE ever compared the 260 rem to a 308.
        Marketing sells I guess.

  2. History is hitting the rinse/spin/repeat cycle.
    The 308 was designed to replace the 30-06 but failed to do so. While the 308 mimics the overall performance of the 30-06 and is more accurate at longer ranges it lacks the ability the chamber heavy rounds. At the pedestrian ranges most used by both rounds the difference in accuracy is insignificant. Now we have the 6.5 Creedmoor whose story almost duplicates that of the 308 vs 30-06.
    While 6.5 provides some incremental improvement in accuracy at longer ranges, the hunting community has already determined the belted magnums (7mm and 300 Win Mag) are better suited for this. So the 6.5 Creedmoor is just another cartridge … although not as ubiquitous as the 308.

    • I agree that the 6.5 Creedmor is just another cartridge, but the.308 was not really designed to actually replace the 30/06 , but the military wanted a round with similar balistics for a faster firing machine gun, M-60 and the issue weapon M-14.

  3. Worth adding to this article— a stat that is measurable and significant— barrel length.

    Creed requires a longer barrel to get the sought-after ballistics. 308 doesn’t, given that its intended range was shorter, and it wasn’t intended for competitions.

    My canned 308 rifle has a shorter OAL, quieter, and softer recoil impulse than most naked creeds with 24” barrels. I’d challenge all of you to compare a canned 308 against a creed for weight, portability in nasty terrain, etc. I think you’ll come to the same conclusion I did. Being able to carry a semi-auto for these ranges instead of a bolt gun is also a significant advantage that I think is undersold here, but I follow why the author went that direction. I assume he wanted to keep apples and apples together.

    • If you practice with your tool (338/308/6.5cm) you will not only gain knowledge but you will gain confidence. There’s a thing called repeatability and you can only gain that with experience. 6.5 cm shooting 129 sst 300 yard 0 (point blank trajectory). Last 5 years in a row 575-690 yard all one shot ethical kills on big northwest mule deer. I can put that same 129 on a paper plate out to 850 but will not shoot to kill past 700. To each his own but I downgraded to a 6.5 cm and realize now that it was just a trade off in inches. The absolute biggest advantage for me is the low recoil as I can shoot every time and watch bullet impact in my scope. 22” barrel ruger American with magpul hunter stock. Not a custom built something anyone can get for relatively cheap under $1000.00 with good moa turret scope. Practice practice practice know your tool and use it as often as you can
