In this video we take a look at 277 Fury and its counterpart 6.8 x 51. We go over our finding from actually getting to shoot these two new calibers.
Please like, comment, and subscribe, it really helps us out.
The way it was moving that plate at 1000 yards was very impressive. Another great video.
Yes and I may should have put it in the video but that particular clip was the hotter 6.8 x 51 loading, but no doubt it has a lot of power for sure. Thanks for watching!
2600 fps out of 13" with the regular 277 is impressive
I totally agree. Get a little longer barrel and it makes it even more impressive. Thanks for watching.
300 blackout sbr with a forward grip switch the barrel out for a .277 instead of a .308
There's 308win factory ammo that will produce similar velocities with 150gr the same barrel length, though that is with fancy powders.
Buffman range tested the 150gr SST superformance from a 12.5" at 2550ish...and that is within the comparatively low regular 308win pressure specs.
To exceed the 135gr ballistics, you'd have to step it up to 155gr ish bullets tho.
Just imagine what a hybrid 308 cartridge might do with 180 or 200grain pills, jesus!
Kick like a 300 win mag, I presume
Barrel and throat life, bruh. We know how fast rounds wear barrels... 300 Win Mag, 300 RUM, 270 WSSM....even 25-06 & 243. If barrel life exceeds 5k rds, this indicates advanced metallurgy. Which means it's going to be HUGELY expensive.
I heard the military would train with the brass ammo then when in combat switch to hybrid.
That's my concern as well. There's no free lunch, physics is undefeated and we know what higher rifle round pressures do to barrel life. The civilian pressure round that doesn't have the special bimetal case will be comparable to what we're all used to but it's also missing out on the capability of the higher spec round. Replacement barrels able to withstand that of pressure over an active deployment firing schedule are a simple, if expensive, logistics supply issue I assume the bean counters have accounted for but can easily be neglected.
The Army already tested the rifles past 13,000 rounds per barrel lol.
I want inconel CHF barrels, that’d be sick lol
The military has enough money to send billions to Ukraine they have enough money to replace barrels.
The fact that you spent all your time and effort on that video for that caliber was excellent keep up the good work love the videos
Man, that velocity bump is wild. That delta is similar or greater than going from a 6.5 Creedmoor to a 6.5 PRC.
Like always, an amazing video with so fantastic information.
Thanks a lot! One of my most favorite channels!
Best regards from Germany
Iam sure sig has tested barrel wear.
I think they said it's good for 10k rounds.
Be awhile since I’ve seen a video from you! Can’t wait to see the rest of this mini series you’ve got going on here!
This is the most interesting video I have seen so far on the Sig Spear. I love the ballistic comparison. Keep it up guys!
Really appreciate you watching man!
The M1 Garand should have been in 270!
Great video! THIS is the kind of real world, head to head data we need. And that's just out of a 13" barrel? Crazy!!
You only touched on it briefly, but yeah, I do think barrel erosion/burnout is going to be a very real problem; one more easily solved with the Govt's coffers than when this is more available out in the Civilian world. My guess is that Armorers are going to have to keep a Logbook with round counts for each rifle, and replace barrels on a set schedule.
This is the best informative video on the topic. It should be a mandatory viewing for anyone seeking to gain insight on the matter. As always AL arsenal impresses on any endeavor they decide to undertake.
The best review channel imo 👍 cheers for the UK 🙏
Just want to give my input from a former infantrymans standpoint on actually using a 5.56 weapon in Afghanistan. I was a saw gunner on my first deployment there, but my company was also attached to Combined Joint Special Operations Task Force and we were attached to a 3rd SFG ODA team. Most operations we did, I did not take my SAW (which if I have to remind, is a 5.56 light machine gun) but would take someones M4 instead if I felt the mission called for it. In more "kinetic" operations where it was guaranteed a large gunfight was to occur (sometimes lasting multiple days), I did bring my SAW. I wanted fire superiority by "volume", rather than accuracy - and that to me was an "operator preference" decision I made on my own going into certain areas. When I did take my SAW, It was configured with whats called the "PARA" barrel...its a shorter 12 inch barrel over its longer barrel as it was more maneuverable around structures and in buildings and it kept it quite light. I just kept the longer barrel in my truck and would use it if i felt a barrel change for heat reasons needed to occur. With that said, we were in NE Afghanistan where engagements were "decently" far. Id say the furthest was around 400 meters and the closet being sometimes just a few meters away. The ranges were quite dynamic. At this time, I was issued the M855A1 ammunition which is hotter load than its predecessor M855 (green tip) and the bullet was redesigned for the tip of the bullet to be steel, followed by a lead core copper jacket behind it (basically its 2 parts), I can recall an engagement I made with that 12 inch barrel on a fighting position of 2 taliban fighters that were around 350-ish meters away. Both fighters had their bodies exposed basically from belly button up firing on other positions of our element, and I fired a few burst strings into their position and they dropped instantly. I did not do a BOGBDA on that position (Boots On Ground Battle Damage Assessment) to confirm where on their bodies I hit them, but ISR (the drone above us) did confirm they were killed. A few operators from the SF team (the 18 Bravos of all guys) preferred their MK18 mod 1s over their ALSO issued SCAR-H using the MK262 ammo (77 grain SMK bullet) and affectively dropped guys easily out at 400 meters and hit that "off button" on some fighters. There were times the Taliban did ambush us on patrols where their positions were maybe 800+ meters out, even way more than that sometimes. Their weapon systems being typical AK47s firing 7.62x39 and PKMs firing 7.62x54R and their fire was so ineffective. They were way out of range for us, we had some snipers come out with us to take them out, or set up some 60mm or 81mm mortars to take out those fighting positions and we took our time doing so because their fire was extremely ineffective given their distance. If anything, we would just call Air Weapon Teams (typically Apache's) and just have them take out the positions and it was a good day. In my opinion as someone whos been down range in Afghanistan where engagements WERE further sometimes than 300 meters - 5.56x45mm did its job. I never really thought a new round or weapon would help me accomplish my job better or anything like that. Some veterans may differ on the opinion but we all had a different experience. Im just showing mine. In my opinion - i think the US Army was taking a look more at statistics on paper, rather than actual battlefield feedback and looked for an excuse to dox the M4 Carbine entirely out of its arsenal and get a new one. The biggest reason it seemed the Army wanted a more capable weapon was the ability to defeat rifle rated body armor. Some have said to me "Maybe we are getting ready for a war with China or Russia" - but my only problem with that statement is....Russia does not issue rifle rated body armor to standard Infantry units and China only started to just 2 years ago and its still a slow progression. So why was the Army in such a rush to acquire a new weapon? I would say to that - use your imagination and think of an "army" that does have body armor. Thats my 2 cents.
I'm curious. Who would that be ? Private maybe?
My thoughts exactly, but who would turn on their brothers?
I said this in comments sections on uploads about this system from the first l saw it. They intend to place themselves out-of-range (yet _very_ able to reach _and penetrate_ whatever opposition they may encounter) of 90% of what they might encounter in the situation you obliquely referred to.
@@dom4002 Many of the newer "employees" would if ordered to, in my humble opinion.
That's alot of words.
I'll wait for the movie
That armor test mention was such a tease!
Another great informative video! I've been following this design and the future military weapons design development since 1995. I've had a few design ideas get developed for the military. Some are currently being fielded. I was but just a 24 year old kid back in 1995, when I had the honor of speaking to Eugene M. Stoner who was literally looking over my shoulder as I was explaining the thoughts behind a design idea, to another engineer. How that under stress and adrenaline, you lose finite motor muscle movements, and that the button on the stock needed to be redesigned, and reversed rather than a button that had to be pulled, it needed to be pushed instead as to facilitate major muscle movements under stress of combat. Stoner was listening in on the conversation, when I saw and recognized Stoner's reflection in the computer screen, I just turned and said to him, I'm just here trying to learn a thing or two... He looked at me and smiled with his characteristic half frown have grin look on his face and nodded his head to me, saying, "yes ,yes , well yes" , he said. I was thrilled just to be in the same room with him. I had originally seen a vision of the 200-600m back up iron sight , as I'm holding a WW2 German FG42, I turned to Doug Olson and said Why don't you make a sight like this? Doug said that's a good idea! I think we will! And the rest is history as they say. From what I've seen the sights on the new military SIG M-5 rifles actually have a updated version of my orginal rear sight design idea. I feel immensely thrilled to see the adoption of the sight with this new rifle from SIG, and to know the history behind the scenes of its idea. All I had to offer was the suggestion of an idea, seeing it into the future and its use by our military makes me very happy to have had just a small role to play in its development.
It should be noted that there is a steel cased, steel tipped 6.8x51 EPR bullet that has only been seen very recently in US Army testing with the XM250
This is the content we need!
Nice Job Tim! Certainly a pretty cool new caliber. Interested to see how this caliber does on the market.
You guys make great content. Best 277 Fury video I have seen.
Extremely well produced video, tons of information here. Thanks
Really appreciate that man! Thanks for watching!
Excellent video, glad to see this come to fruition.
I cannot wait to get a hold of one of these rifles and this cartridge. Makes you wonder if they could update the 6.8 spc with similar tech and go to the m4 carbine size weapon with a smaller barrel and get not the same performance but much better than current
Big thanks to Alabama Arsenal for dropping fire on a Sunday
I’d far rather see 6mm arc or 6.5 Grendel with it
But 556 would also preform better
6.8spc sucks 👎🏼
Great video. The best I’ve seen of the 277 Fury and 6.8 x 51 but no mention of that new CGS can I see.
Not yet, with the new YT interpretation of the rules that video might have to be a Patreon only video. We'll see, I just got done serving a YT suspension so it's kind of touch and go at the moment. Thanks for watching!
Your instruction and knowledge you share for your viewers are awesome. Thank you!!
Really appreciate that D, Thanks for watching!
Especially considering having Alabama in the name! 😜
amazing video, never seen any of your stuff before but I am fully impressed with the production and professionalism of this video!
Go back through their video catalog, they've always had excellent Production and editing :)
@@BattleshipSailorBB63 I checked out a few other stuff yesterday after watching this superb!
Blown me away with your literally perfect optic choice for this rifle. Between this and 4-16 ATACR for when I get my spear heavy 😉
Have yet to shoot the round myself, but the math of it alone is amazing. I hope the 8.6 BLK gets some serious development and becomes to the .277 what the .300 BLK is to 5.56
I’m a fan sig did a great job designing and making this all come together the m5 and the new round along with the new optics that’s coming as well.
Holy… out of a 13 inch barrel that’s insane. Literally next level kind of ballistic potential.
According to Sig they are using a new barrel process that allows barrels to be way more durable. This process is superior to HF . Sig has hinted to this process but hasn't even released any good info on it either . The M5 barrels per TDP is supposed to last 12k - 15k life expectancy.
I'm actually pretty interested in picking up Sig Cross 16" 277 Fury . Seems to me like to would be solid choice for LW Hunting Rifle for Lower 48 .
The XM5 barrels are made out of an unusual and expensive steel called Maraging Steel, which is also used inside jet engines to withstand afterburner. It's so unusual that it's a closely monitored material by the US government as it's highly suitable for uranium enrichment centrifuges.
WOW! I did not know that, very interesting. Thanks for watching!
Thanks for this VERY enlightening video. In addition to a great cartridge and excellent rifle SIG has also developed the best suppressor for it because it does NOT blow gasses back to the shooter as does virtually every other suppressor design. SIG did it with a complex baffle system that could only be made by 3D printing.
-> And then there is the great Vortex sight system for the M7 that gives average soldiers an 80% hit probability! Thus no need to carry a big ammo load out as with the 5.56 NATO round.
the opening scene 🔥love how the background moves vs the shooter/rifle.
Love the explanations!! Can't wait for the next video.
Phenomenal video.
Thank you!
Very informative. Been waiting for some ammo testing.
Ahhhhhh, come on bro. You left us hanging with the level 4 plate. lol. In all seriousness, awesome video. 🤙🏼
I believe SIG reps stated max PSI for the round is actually near 120k, but the first loadings will be around 80k. I bet the military will be given a higher pressure load with a steel penetrator similar to the m855a1 going nearly 3k fps.
These Hybrid Cartridges are absolutely insane and a game changer! I was reading online that a guy took .308/7.62 calibers and stuck them in 6.8 x 51 Hybrid Casings, and was able to get a 168 grain projectile moving at over 3,256 FPS in a 24 inch barrel. That's over 3,900 foot lbs of Energy! 300 Winchester Magnum territory!
I can honestly start to see other companies creating similar products for other cartridges like 5.56, 7.62 x 39, etc. It would just make these already great cartridges even more potent!
That is how it's done !!! Great job
As usual, top notch video. Love the content. I have a spare AR10 receiver set in my safe.
277 sig fury may be a worthwhile build.
Hitman industries has them
Great video ! I'm very interested in the new .277 round and the entire MCX line. Unfortunately my wallet told me 'hell no' when I asked if I could buy a Spear LT. So, UA-cam vids are as close as I can get to seeing one in action. Thank you
That first scene… How did you film that? It’s revolutionary! It really shows how the rifle works.
Damn she shoots smooth! I’m interested in this caliber having ran 6.8 SPC for the last 7 years.
It is a very interesting caliber indeed! Thanks for watching!
checkout the 6 SPC. It is what should have been chosen
@@davidpeterson6147it’s completely different 🤦♂️
This is a really neat rifle that also has zero business being a replacement service rifle.
Something like Tavor 7 but in 6.8x51 is now my dream gun
Well done Sir!!
I like it. But it seems like a bit too much juice for cqb. Perfect DMR. But what im more interested in is the ammo tech and actions that handle those pressures. Imagine applying 80ksi to a 6arc or even a 556. Getting a 108 gr bullet at ~2900 fps out of such a small cartridge would be awesome for all applications...
That round still has a lot of energy even at 1000 yards. I think you would have no issues running the softer shooting stuff for up close work.
I completely agree, really the softer shooting stuff is still pretty potent. Thanks for watching!
@@AlabamaArsenalalso longer barrel life, especially when your putting lots of rounds down range for training and combat
Thanks for the work.
Appreciate you watching!
Never disappoints you guys rock
Appreciate you taking the time to watch!
Great informational vid, my fellow Alabama brethren! 👍👊 Nice!
Really appreciate you watching!
Excellent rundown!
Really appreciate that man! Thanks for taking the time to watch.
Beautiful, I'd love a 277.
Yes I do believe I will be in the hunt for my own 277 Fury as well. Thanks for watching!
One of the answers to the problem; "Good ballistics, short length" is; "good bullpup". They would never need the same pressures to achieve the same velocity; safety, longevity, take your pick, it's a good thing. I would love a technical answer from Sig themselves about this
No need. The Army decided that. One of the submissions that was rejected was a bullpup. Textron maybe?
Very nice as always
I’m definitely buying it one of these days
Awesome analysis.
Really appreciate that man! Thanks for watching!
Deployment ONLY 6.8x51mm is the only full power round. It makes the necessary velocity at short military issued barrel to penetrate armor at required combat distance.
Lofi runaway beat was a nice touch 👌🏼
Finally an exciting new cartridge!!!
Seems like it would be a great round for a compact hunting rifle. I personally would love to throw my suppressor on a 16” barrel that produces the same ballistic performance that I get out of my suppressed 22” barrel. Much more handy.
“ No educated guesses “
Now that’s information that is useful. 👌
Looking forward to the second part.
Man that’s bad! Love the looks of it
Seems like a lot of trickery to perform as .308 while burning barrels 🔥
Can't thank you enough for sharing the dope on the matter 🤘
there will be an overheating issue as well as higher rates of extractor breakage and bolt wear due to the steel part of the case.
No problem, appreciate you watching!
It does have dual extractors, I'll cover that in the video just about the gun. But not doubt, there are a lot of issues to overcome for sure. Thanks for watching!
Interesting, thanks for the video. I haven’t checked but could one build a 277 on an AR10 platform? The 308 bolt should work but in not sure if barrels are available yet. What about reloading supplies like brass? I’d certainly prefer a 18” or 20” barrel if I ever build one.
Too bad sig is too busy to get me a barrel change for my sig cross
Trying to get a shorter barrel for my 300BLK MCX, but the prices are way too high.
BROTHER. YOU. ARE. THE. BEST!
Appreciate you watching!
Not gonna lie, sometimes I watch these videos just to hear his soothing voice 😊
🤣🤣🤣 just glad that you’re watching! Thanks brother!
The hybrid metal case that Sig designed for this cartridge is easily the most significant advancement in small arms in the last 100 years.
One day I will buy one of these fine machines!!!
I hope to own one of my own at some point as well. Thanks for watching!
Would you be able to post a google sheet of those ballistics tables? Fantastic data, I'd love to be able to pull it into my own comparison spreadsheets. I'll get to work manually copying it over, but I think a lot of viewers might appreciate it. Loved the video!
Available on my Patreon Page, All loadings used in this video. Thanks for watching!
Can't wait to get into this for hunting things 😉🤠
Cool video! Thanks!
I need that buffer style tube for my Spear LT.
Kanye Runaway beat around 7:30 made this video that much better
Thank you!!! Can't wait for the cross in this caliber.. Please hurry Sig!!
TLDW: 13" barrel in 6.8x51 performs the same as a 20" barrel in 308. That's impressive. Not sure if I want to carry that weight but it's impressive
Hella impressive and then consider that 6.8x51 has higher sectional density than .308/7.62 NATO, so it's gonna be much better at penetrating body armor
The thing is that you can just change 13" barrel with 20" barrel and that is a sniper rifle for everybody, when you need that (mountains of Afghanistan etc.).
better, 308 goes subsonic way sooner than 277
3:32 that side turret is coming loose, hope you caught it in time lol
Great video, I did want to hear about recoil, I see performace wise its great to see that much power from a 13" barrel thats incedible. How is the recoil though, can it even be managed on a full auto fire, in relevance to the 308?
That rifle still weighs and kicks too much for wide adoption. Still, awesome video!
that rifle weighs exactly the same as HK416 rifles Marines currently use ...
look up any currently used rifle and you will see its around 4kg/8lb just like the M7, whats heavier is ammunition
@@Asghaad and the optic and the suppressor. Still kicks too much for little people like task and purpose.
@@ryanvalicek7291 both optic and suppressor will also go on the HK...
And that's the recruitment/personal distribution problem, put weaker/smaller into vehicles not on front lines, if someone can't handle weight and recoil of the rifle that's lighter and with less recoil than Garand ... Maybe they just aren't cut for infantry duty...
Time will be the final judge of how everything hold up to rounds that hot....
Very true! Thanks for watching brother!
Adopting the 6.5 creedmoor and the 6.5 grendel makes so much more sense !
Cool video thank you
Appreciate the videos ya'll. From NW Bama 🐍🇺🇸
Awesome man! Thanks for watching!
Great to see a historically very important German company lives on with their new HQ in the USA and providing the new US service rifle. J.P. Sauer would be proud.
It is kinda cool isn't it. Thanks for watching!
They need to do the same thing with the 5.56. Neck it down, use a longer solid copper bullet and add a steel base for higher pressures. Copper is needed for the speeds they could generate.
Don’t worry. It’s coming. There’ll be dozens of rounds coming in all calibers.
if you want a faster 556 then there is 22-250
6mm ARC is kind of that idea.
@@lefunnyN1 Not in a small frame AR platform silly goose
@@KeterMalkuthI’d be more interested in them experimenting with powders to achieve nicer burn rate and velocity out of shorter barrels.
Awesome video brother! Glad to see that you’re out of the “doghouse”
You and me both! Hopefully I can stay out of the doghouse. Thanks for watching!
Can't wait for the level IV video!
Very soon my friend! Thanks for watching!
One of the other stated reasons for the change is body armor penetration.
I still say the platform is fine, but going back to a battle rifle cartridge is wrong it’s a lesson we will have to relearn.
Great video brother!!!
Appreciate you watching man!
Good vid, so how does the Comm-bloc fair against the Sig rounds?
Really would be curious to see data for 308 hybrid of same gr loaded to 80000psi chamber pressure in a 13" barrel. I'm willing to bet velocity would be higher. Which would mean less barrel life. BC would be worse meaning more drop and less 'energy' on target. The only thing I wonder about is the affect that projectile diameter has on targets down range. .30 has proved to be particularly devastating. I'd like to see how 277 stacks up on physical targets
Faster bullets burning barrels is a misunderstood concept. It's not the speed that burns the barrels; it's the slower-burning powder used to push the bullet all the way down a longer barrel. It is the powder burning down the barrel that causes them to crack.
Along with millions of hunters, I can verify that the 270 is very effective on physical targets.
There is fancy and costly factory ammo that duplicates the 277 13" velocities in the 308 within standard pressure specs.
150gr Hdy SST at 2550fps from a 12.5" according to some test buffman did a while back if I remember correctly.
This projectile is not as ballistically efficient tho as the 135gr .270.
Now if you could make a 155gr Berger HT move at the speed of the 150gr SST, your 308 would actually outperform the 135gr fury load at all ranges...
The 6.8/.277 is the 6.5 Creedmoor on crack.
Be really nice if this would become as common as 6.5 is now.
That would be nice. Thanks for watching!
Something people may be interested in I’ve heard that the military is loading their ammo to90,000 psi to 100,000 psi and there’s going to be an armor piercing variant which will be a tungsten penetrator loaded to 120,000 psi versus the 80,000 psi version that the civilians can get
That's probably what it would take to get the performance they're looking for.
Would love to see this in some timed run and gun scenarios to see how well it handles in comparison to an AR15 and get your feed back on it. Honestly just watching you guys shoot it free hand looks a bit cumbersome.
I want to see what 6.8 x 51 will do through a 16in to 18in Barrel. I think it would be just totally nasty if it's performing that well through a 13 inch barrel. Especially if a company loads a 6.8x51 specifically for longer barrel. I want to see parts for these become common, including 3rd party.
I like how this video is made.
Would be great to see SIG finally offer the Cross in 277 Fury.
Steel is less dense than brass. (You pointing out the weight of the cartridge)
Maybe it’s me, but I still believe we should have used the 6.8 SPC using the hybrid case in the XM7 and the XM250. Designated marksman rifles should be the 277 rifle and have a xm250 with 277. Heavier hitting ammo while losing only I think it’s 3 rounds with current mags but I know magpie has a 30 round one.
