- To meet military needs, SIG Sauer had to come up with a revolutionary new cartridge design. The company succeeded with the release of its 277 SIG Fury.
In developing a system for entry into the U.S. Military's Next-Generation Squad Weapons trials, SIG Sauer has spent much R&D time, energy and money into optimizing the round required for these future firearms.
One specification required for NGSW entrants was the use of a 6.8 mm round, and SIG's answer was a specially designed hybrid case for the bullet. Commercially, this unique cartridge design came to be known as the 277 SIG Fury.
To meet the velocity and energy needs of the U.S. Military while retaining a 6.8 mm round, it was necessary to increase the pressures used in propelling the round from the barrel. While the 5.56 NATO runs at pressures of around 55,000 PSI, the new 277 SIG Fury required chamber pressures around 80,000 PSI.
For guns and cartridges to withstand these increased pressures without failing, a revolutionary case design was created. The 277 SIG Fury has three components in the cartridge case, all of which work together to create more capable ammunition than has ever been seen before.

The shell looks too big to go into a regular sized rifle to me.
Lmao 😂 🤦♂️
Same. I think its the camera/angle.
🤣😂
A lot of people in this comment section don’t seem to realize that this round wasn’t made for civilian/sporting purposes.
It was made for the U.S. Army NGSW program.
Just super cool high tech and I thank you for showing us the inside how that case works. Now, is it reloadable? Case life? Powder availability? I want this to be everything they say it is, but there are some serious questions being left unanswered.
This looks shell shock technology. Good stuff
I'm interested to see how current calibers could be improved with this technology. Like 5.56, 7.62x51 ect
5.56 is a wimpy semi-lethal Cartridge designed to wound (in the 55gr ball configuration), it's really more of a small game Cartridge for Coyotes and Prarie Dogs. Also, the pressures they're talking about are kind of excessive. 80,000 psi, 15,000 beyond a 500 smith and wesson magnum, or bog standard magnum rifle Cartridges? Are you trying to burn the barrel on the way out? If you need that much more energy, use a bigger bullet. If the Arguements were based in range, versus saying, "The energy is what we want", I'd have no problem. You want energy? Use a 300 Win Mag, use a 408 Chey Tac, use an 8mm Mauser. Speed may have a Quadratic effect on the paper numbers, but I have yet to see a Professional Hunter in the Safari mainline a 6.5 Creedmoor to stop an Elephant that's pissed off.

Barrel wear is not so much dependent on pressure as peak temperature and the mass-flowrate of hot gasses through the throat. Modern powders are less erosive than standard double or single base powders by way of lowering peak temperatures.
@@nikolibarastov4487 you are wrong .556 was NOT made to wound lol brownells made a whole video on this I U fool
@@nikolibarastov4487the problem with just using a bigger bullet is that the reason the U.S. army adopted the 5.56 in the first place was because it allowed soldiers to carry more ammo because it was smaller and lighter than a full size rifle round while still having the range and lethality to deal with enemy combatants.
Using this technology on existing calibres like 5.56 could likely give them the power of 7.62 NATO without having to sacrifice ammo capacity.
I understand this was for military use but I'm pretty sure the Hornady superformance already launchehas a .277 projectile at 3200 feet a second out of a 24-inch Barrel in a 270
But will it do 3k out of a 16? That's the whole point from what I'm gathering as he said smaller set ups would now have more power
So basically twice the range and energy of 5.56 with less drop than 6.5 creedmoor
With the recoil of a 7.62 x 51 in a rifle that can handle 80,000Psi pressures and the round 20% lighter than what? a 7.62? So what happened to an "intermediate" round like the 6.8 SPC? This is a 7.62 replacement. Sounds like the brain child of the grand kids of the clowns who replaced the 30-06 with the 7.62.
@@baobo67 The problem is no intermediate round can perform the requirement, which is penetrate level IV body armor.
hey sig how do i buy that large cutaway model? thats cool as hell.and can we reload it?
Much shorter barrel life!
What if this style change to 556 ?
Why can’t this tech be applied to say 308 or 223. Wouldn’t that make those cartridges better as well????
Make a high BC 150 grain and we’ll call it a day
Why not just go with a full steel case?
Likely weight and cost
80,000psi per shot? Well, that's gonna be hell on the barrel...
Not on my patented titanium sleeved barrel, chamber pressure alone doesn't burn barrels, it's velocity, duration of heat, RPM and other stufff.
@@claudiodominguez. You do realize that hot metal alloy becomes more malleable, right? On a conventional assault rifle, this would make the barrel expand like a balloon with rapid-fire of the new .277, which could lead to rifling no longer making contact with the bullet, and possibly eventual cracking of the barrel. Unless an alloy that is lightweight, cheap, and capable of withstanding the extreme conditions of this round is developed, I don't see the .277 FURY going mainstream in the foreseeable future.
Plus, it's expensive as hell: $2-3 per round, compared to $0.60-0.80 of individual 5.56 NATO rounds. I don't think even the US military would have the budget to sustain that kind of ammo cost for each infantry unit. At this point, it just seems to be a proof-of-concept, experimental type of ammunition.
Another flop! I'll take the old 260 rem
Over the 6.5 creedmour or the 277 signs fury. They say their the first to load cartridges in this high of pressure's but Weatherby has done it for years. Does anyone know if these hybrid cases can be reloaded?
How is this any better than a 300 Winchester Magnum? I ask because that's really going to be the comparison, because the 300 Win Mag is already wodely available and can take an Elk-Sized target at up to 300 to 400 yards in the wind...
It’s smaller and has better velocity.
But it should be mentioned that the .277 fury isn’t meant for hunting.
My question is how much do they cost? Availability? Way too specialized? Is it proprietary? Sources for ammo/components? In today's world I see a lot of problems for a citizen to consider this as an option.
gee,, i did not know anything could beat a 6.5 creedmoor , a 6.5 creedmoor gets about 2650 mv with a 140 bullet and a 22 inch barrel,,,,,on average,,, not much,,,,,,,this 270 is the way to go,,
How does that compare to the 6.8 western??
.277 has much more velocity and much less bullet drop
I think, the major benefit would be lower production costs. Much easier to produce cases out of brass tubes, than to go all the way casses were made so far. The higher rigidity of the cases' bottom is a rather a secondary benefit. Along with the possibitity to make breach/bolt system less solid and thus lighter in weight.
"Lower production costs"? Even when ammo prices are down, these new rounds can go upwards of $60 for a case of 20. I doubt the military would be able to sustain costs like that, so we're probably gonna stick with the more cost-effective 5.56 NATO rounds for now.
@@MilesEdgeworth129 Everything's expensive at low rates of production... 5.56 NATO wouldn't be cost effective is nobody was making it.
@@MilesEdgeworth129 Despite how the Army advertised this, I don't see this as a replacement service rifle since it is the same size as a 308 cartridge. It appears they are adopting it to replace the AR-10 platforms. In other words this is a new DMR platform which makes sense why they want such a flat trajectory so shooters don't have to be up to date on their DOPE as much. Personally though, I think they should have made a 300 win mag semi auto or similar instead.
Just because it's being offered by a company, does not make it great. 80kpsi near my face, in a regular design gun? Ever hear of the grunt factor? No thank you...
How is 80kpsi safe but 60kpsi unsafe? Believe me, if that 60kpsi got loose, your face would be just as wrecked.
Is this round considered a 280?
280/7mm =.284". 270/6.8mm =.277"
Earl Wilson it’s a .277. A 7mm or .284 would be “280”
I believe it's a 270 with a bullet diameter of a typical 270 round (.277) where the 280 is .284
.270-08, its a .308 case necked down to accept a .277 boolit
I think the idea is good, but it's gonna flop, because at this time, no reloading, short barrel life (prob around 800-1000 rounds), and if it can't be reloaded no one outside of military is gonna but it. Hell the case alone is gonna be double what a standard brass case costs due to the engineering, wear n tear on the machines that make the head of the case.
Agree except for the manufacturing part. I think these cases can be made a lot cheaper than brass cases. It is much easier to turn steel than to draw brass cups. You need far more expensive and specialized machines to draw brass, while any auto feed lathe can make the components for the head on these new cases.
Nope
sounds like in some years this will be as useless as the magnum belt...
that price make's it the biggest rip off of american tax dollars ever made.
6.8 them taxes spend grate, thanks americans.
