277 Fury Vs 6.5 Creedmoor: Long Distance Dominance

When deciding between the 277 Fury Vs 6.5 Creedmoor, which one is best?

It all depends on several factors, including what you plan to use the cartridge for, which is why I've forced these two rounds head to head in several scenarios to determine which is best.

However, I have a feeling one has a significant advantage over the other. Let's get started to see if it is accurate or just in my head.

.277 Fury vs 6.5 Creedmoor Caliber Comparison

Below, you'll find the .277 Fury and 6.5 Creedmoor compared across many factors and scenarios to help you decide which is best for your situation. At the end of the article, I'll tally up the winners of each category and reveal the overall winner.

But first, let's start with the cartridge specs for each to help you grasp the size difference.

Cartridge Specs

The 277 Fury claims it doesn't have a parent case; however, it's nearly identical to the 308 Winchester and 6.5 Creedmoor with the same length and diameter as the .308 Win. The 6.5 Creedmoor is based on the lesser-known 30 Thompson Center, but the cartridges are comparable overall.

In fact, I don't recommend shooting them side-by-side as they could easily be misidentified and create a catastrophe when loaded into the wrong rifle.

The most significant difference between these two calibers is the max pressure. As of this writing, the SIG Fury has the highest pressure of any cartridge approved by the Shooting Arms and Ammunition Institute (SAAMI).

The higher pressure is intended to achieve body armor-piercing capabilities at 500 yards. Sig Sauer can safely produce this high-pressure, thanks to the 277 Fury hybrid case, which utilizes a brass body and stainless steel case head joined with an aluminum locking washer.

While it's still unproven, barrel life is a big concern for shooters. The higher pressure is expected to shorten the barrel's life drastically for competitive shooters.

Just by comparing the two cartridges based on size, the 277 SIG Fury is slightly larger, and bigger is always better, right?

I guess we're about to find out!

Recoil

Maybe I'm just a wimp because I believe recoil should be a significant consideration when buying a new firearm, especially for long-distance shooting.

Many new shooters are scared of feeling the thud of a rifle slam into their shoulders, which is why they are concerned with the amount of recoil. While more experienced shooters understand that less recoil tends to mean more accuracy, not necessarily that they're scared of the increased recoil.

Recoil is primarily affected by muzzle velocity (FPS), powder charge, bullet weight, and rifle weight. So, there is no perfect comparison; we must assume all things that can be equal are equal.

The 277 Fury has a felt recoil of about 20 ft-lbs, which is very comparable to one of the all-time great long-range cartridges, the 308 Winchester.

The 6.5 Creedmoor edges out the 277 Fury with 17 ft-lbs of free recoil. However, it's not likely you'll notice much of a difference when shooting these rifles.

The higher chamber of the new cartridge creates a little more recoil and causes it to lose the first category to the 6.5 Creedmoor.

Trajectory

Knowing the bullet's trajectory is essential in long-range shooting. I have yet to meet a shooter who prefers a trajectory that looks like the first half of the McDonald's golden arches over a flat line.

Because both calibers were designed for long-distance shooting, it's fair to say they'll both have reasonably flat trajectories.

Zeroed in with a 150gr polymer tipped Nosler bullet shot through a 16-inch barrel length at 100 yards, the 277 Fury drops 3.1" at 200 yards, 24.6" at 400 yards, and 43.7" at 500 yards.

When the 6.5 Creedmoor is zeroed in with a 147-grain bullet (ELD-M) at 100 yards, it drops 3.8" at 200 yards, 29.5" at 400 yards, and 52.7" at 500 yards.

As the distances increase, it's evident that the higher chamber pressure of the 277 Sig Fury allows the bullet to have a flatter trajectory.

The 277 Fury ties it all up by winning this category.

Accuracy

Due to all the factors that go into it, determining the accuracy of a round is challenging. The bullet, gun, shooter, and conditions all factor in, so I'll do my best to make them as equal as possible for a fair comparison.

I also believe recoil and trajectory are significant factors, so I typically use them to determine the winner of the accuracy category in my other cartridge comparison articles.

However, since each round won one of those categories, and I don't believe in ties (one reason I find it challenging to watch soccer), let's dive into the details.

There is no denying the 6.5 Creedmoor is incredibly accurate. It's constantly winning long-distance shooting competitions and is more than capable of making a 1,000-yard shot. But the 277 Fury has a flatter trajectory and only a minimal amount more recoil.

I must go with the 277 Fury being more accurate, especially at longer distances, thanks to the flatter trajectory.

Ballistic Coefficient

The ballistic coefficient (BC) is how aerodynamic a bullet is mathematically and how much it resists wind deflection.

Longer, heavier bullets generally have a higher BC. A higher BC means the bullet is more streamlined (aerodynamic), better resists crosswinds, and is less susceptible to wind drift than lower BC bullets.

Anything over .500 is considered very good, and both cartridges hold bullets capable of exceeding a .500 BC.

The 277 Fury 150gr polymer-tipped bullet has a BC of .500.

However, the 6.5 Creedmoor Hornady 147 gr ELD-M has a BC of 0.697.

The 6.5 Creedmoor has the better ballistic coefficient of the two rifle cartridges.

Stopping Power

Read any one of the gun forums, and there's always going to be someone concerned with stopping power. What do they mean by "stopping power" exactly?

Well, they could be talking about the size of the hole the bullet leaves, how deep the bullet penetrates, or how much energy it transfers to the target. Or a combination of all three.

None of this matters if you are only a target shooter, so if that's you, go ahead and skip to the next section. But if you are a hunter like me, you should stick around.

The 277 Fury bullet has a slight advantage because it leaves a slightly larger hole, but I don't believe it to be a significant advantage. Both bullets dwarf compared to the 338 Lapua Magnum, which propels a 250-grain bullet at nearly 3,000 fps.

The long, slender design also helps both bullets penetrate; however, the 277 Fury was purposely designed to pierce body armor at 500 yards. However, I haven't seen any deer, elk, or coyotes wearing body armor lately.

Lastly, both cases can hold a 150gr+ bullet, but the 277 Fury cartridge propels the bullet faster, transferring more energy into the target it hits.

The 277 Fury cartridge has more stopping power than the 6.5 Creedmoor, no matter how we look at it.

Hunting

Neither round was developed for hunting, but both can take small and medium-sized game, such as deer, pronghorn, coyotes, and hogs.

The 277 Fury can also ethically harvest elk, which gives it the advantage in this section.

Home Defense

I'm not a fan of using rifles as home defense weapons. Yes, the M4 carbine chambered in 5.56 NATO is used in urban combat environments, but protecting your home is different from a military operation.

Even with a suppressor to dampen the noise, you must still concern yourself with overpenetration when shooting a rifle cartridge, whether a short action, bolt action rifle, or a semi-auto AR-15.

That's why I still prefer shotguns for home defense over rifles or pistols, but if it's all you have to defend yourself or your family, then use it.

I would reach for the 6.5 Creedmoor over the 277 Fury in a home defense situation because it has less recoil and is slightly less likely to punch through multiple walls.

Ammo & Rifle Cost/Availability

The availability and cost of ammo and the gun are significant determining factors when I purchase a new rifle.

The availability of ammo also matters because what good is a gun if you don't have ammo to shoot? It's an overpriced paperweight and a very poor club.

That's why the 6.5 Creedmoor easily takes this category. You can get 6.5 Creedmoor ammo, which is much cheaper than 277 Fury ammo. However, 6.5 Creedmoor rounds can be as pricey as 277 Fury rounds.

The Lake City Armory, which Winchester Ammunition manages at the time of writing, makes 277 Fury ammo for the military. But on the civilian side of things, only Sig Sauer makes Fury ammo that you and I can buy.

6.5 Creedmoor ammo is much more readily available because companies like Hornady, Remington, Winchester, and many other manufacturers make 6.5 Creedmoor ammo.

The same remains true when buying a new rifle. The Sig Cross, a bolt action precision rifle, is chambered in 6.5 Creedmoor and 277 Fury, but it's much easier to find in 6.5 Creedmoor.

Sig Sauer is the only company making 277 Fury rifles, which increases the price. For example, the Sig Sauer MCX-Spear, the semi-auto civilian version of the US Army's XM7 machine gun, costs $8,000.

On the other hand, you can find 6.5 Creedmoor rifles in all price ranges, from $500 to several thousand dollars.

The 6.5 Creedmoor takes another category because it's less expensive and readily available to civilians.

Reloading

To save some money, shooters often reload. It saves money in the long run and allows you to control every variable of the ammo manufacturing process, so you get higher-quality ammo.

There is a ton of information and reloading supplies for the 6.5 Creedmoor, but the same can't be said about the 277 Fury because it hasn't been around long enough.

It's also yet to be determined how the hybrid case of the 277 Fury will hold up to reloading compared to the traditional brass case of the 6.5 Creedmoor.

Keeping this section short and sweet, the 6.5 Creedmoor takes the final category.

.277 SIG Fury Development

The 277 Sig Fury is the new cartridge Sig Sauer created for the Next Generation Squad Weapon Program (NGSW). The exact details of the development of the 277 Fury are still classified, but we know the US Army needed it to pierce current and future body armor at 500 yards.

The creation of the 277 Fury was first announced at the end of 2019. However, the SAAMI committee members couldn't meet until 2021 to decide on approving the new cartridge due to COVID-19 travel restrictions. It was eventually approved and is currently being produced at Lake City Arsenal.

As civilians, we're patiently waiting for more companies to add the 277 Fury to their ammo lineup because supplying the US Military with small arms, ammo, and rifles remains the primary focus.

6.5 Creedmoor Development

Dennis DeMille is credited with creating the 6.5 Creedmoor, the Ultimate Cartridge. DeMille began working on the cartridge after being approached by several long-distance shooters complaining about the 6mmXC, which was damaging their rifles.

So, DeMille set out to create a solution. In 2007, at Shot Show, the 6.5 Creedmoor debuted. It had many skeptics at first, but since then, it has become one of the best-selling rounds, second to only the 223 Rem.

It's capable of ethically bringing down big game and shooting 1,000 yards at the range.

Parting Shots: 277 Fury Vs 6.5 Creedmoor

Now that you've finished reading this 277 Fury Vs 6.5 Creedmoor article, you might be wondering why the US Government spent so much money and time developing and buying a new cartridge...All I can say is it's the government; most things they do don't make any sense.

If you kept track, you'll have counted 5/9 wins for the 6.5 Creedmoor and 4/9 wins for the 277 Fury. While close, I think most shooters will prefer the 6.5 Creedmoor over the 277 Fury.
