I like the flurry of .270 caliber cartridges recently. I love the risk taking innovations. I wish them success. I think it may turn out to be a flash in the pan, though.

Like most things Sig, it sounds expensive. With the chamber pressure that high, corresponding bolt thrust, barrel wear and cartrage casses needing expensive material and machining, I don't see it being taken up by the masses. The full hotrodded version doesn't touch the .270WSM/6.8 Western except less powder burned in a bit smaller case. If the civilian version is dumbed down to make it cost effective, I don't see very much gain verses what is already available. The 6.8 SPC II is within sight and the 270MSR is already looking at nearly the same ballistics for a lot less engineering money.

 

Just one more round that is not currently available. This ammo situation is nuts.

 

When it finally comes out I'll bet they recommend against reloading...1 use case.

 

A two piece case with a stainless base and brass body? Yup, not reloadable.

 

Military has gone full circle with this back to 1939-40. M1 Garand was originally chambered for the 270. Gen MacArthur had them change it to 30-06 because the US had millions of rounds from WW I.

 

Not exactly. It was originally chambered for the .276 Pedersen. It actually fired a 7mm (.284) projectile. .276 Pedersen - Wikipedia

 

You know, I went with a 270win for a LR rig because the unpopularity of the 277 catridges for anything other than hunting.

Now, you have a few different .277 stuff coming out.

This is awesome.

I'm still trying to figure out if I wanna skip the 270 all together and go with a 270 sherman...... 31xx FPS with a 170gr berger sounds great. But at the cost of fireforming and dies that are expensive.

Either way, I'm gonna be sticking with the .277 for a while.

Now if I could get a 270-08 barrel for an AR.....

 

If we're going to burn barrels with a .277 why not with the WSM or SAUM?

Guts ventured he thinks that they may come out with some "Toned Down' lower pressure loads in brass that could be reloaded.

If KAG has actually successfully made a bolt that won't fail in a standard DPMS Upper with the SAUM or WSM then who cares about the Fury. I am taking a 'wait and see' position. Armalight says that they have issues and can't get it done...

We have been looking around at various bullets there are definitely some good 277 candidates. Even some heavier solids that might work.

 

Interesting

I think it is a conspiracy , lol. Now that ammo for the guns we already have has all but dried up manufacturers come out with new chambering and stock the shelves with ammo to fit them . Reason says buy the gun you can get ammo for . I was at two lgs this week and both had plenty of 6.8 western but not much of anything else .

Our local Academy had Hornady 120 gr. 6.8 SPC yesterday for $26.xx per box. I wasn’t there until the afternoon and they were down to a partial case, but it was a good sign. I don’t need any so I left it for someone who didn’t plan ahead.

 

Sooo. Where is that Academy??

 

always better alloys out there that come with a price and some way difficult to machine. Adds cost. Sig will prob sell an upper for $$$$$. Doubt there will ever be a way to roll your own.
To me it is all about the SA. Much prefer my WSM bolt gun over the LA due to bolt throw and weight. In ARs I have 2 in 30AR. 308 ballistics in a much lighter rifle. My 308s have taken a back seat on hunts. It is hard to lug a AR10 through the woods when there is a 30cal AR15 next to it in safe.
I am in for a Cross when available!!!!

 

The .277 Fury is bound to be a barrel eater. All the various surface treatments plus hammer forging are a good start. Note that US Army Ordnance Corp put a Stellite insert into late model .50 cal MG barrels to combat erosion. Much depends on which of the 3 NGSW contenders wins out. Sig's barrel erosion problem will undoubtedly be a factor. - cw

 

I believe barrel erosion will be a problem for ALL the contenders as they all must reach the same performance level. I believe that regardless of how they reach that level they will still have high flame temps and duration. It seems that 3000 fps is a point where barrel erosion becomes a problem. Getting this velocity in a shorter barrel probably causes a bigger problem.

 

Although I have not seen specifics on chamber pressure, General Dynamics decided to run a 20" barrel with a bullpup, so I suspect that it will be easier on barrels. They are using the polymer "neckless" cartridge, so maybe they simply cannot run as high a pressure. I know that there have also been quite a few projects over the years to make more durable barrels, but have not seen any claims that new alloys or coatings were used for this competition. It IS possible, though.

 

Just a complete waste of time and money, where maybe we could push it towards more important things. What does this do that the current M4 is unable to? We already possess a bullet in 5.56 that can penetrate any body armor that exists on the planet.....

This entire hoopla of faster velocity and better accuracy doesn't matter because at the end of the day, killing is killing and 5.56 has done plenty of that and we got the entirety of NATO on it. If they wanted to move towards a better cartridge, 6.8 SPC II and .308 already exist and in numbers easy enough to change to.

 

Not just about what exist today, but what will exist. Safe Life FRAS is already a flexible armor that can stop 5.56 and .308 and 7.62 x 39. Hell I saw a one off version of thier armor stop a .50 from a Barret at near point blank range, (you would still be hurt from the concussion) So technology is already getting there.
