SIG's new .277 Fury round

No

I’m not going to be burning up the road to go buy one.

If the military adopts it people will be tripping over themselves to buy one. I like the concept if it lives up to the marketing so I would be open to buying one, but I'm pretty flush with deer rifles at the moment.

.277-08? Meh.

Nope it will flop

That "hybrid case" gives me *the willies*!

I'll log it in with .45 gap and .357 sig.

My breath, will NOT be held during this, the next long-death of a heralded answer to unasked questions.

Military looking about for things to spend money on, not withstanding.

Is it reloadable? I'm not a fan of anything being introduced that the "commoner" isn't able to reload.

Someone want to explain the advantage (if any) of the hybrid case?

Holds the psi better.

I kinda like the new round, if anything you can just use it as a 270-08 with normal psi ammo. I want a 284 fury.

Thanks - I was curious as well.

This.

There have already been a few threads on the .277 Fury, but basically it was developed as part of Sig's entry into the NGSW program, hence the .277 bore. The Fury ammo runs at ~80ksi and basically gives .270 WSM performance in a .277-08 package. The specified twist rate is 1:8.5 and the cartridge is currently being standardized with SAAMI. Sig has stated that a 6.5mm version is in the works, and long action variants with the Fury case design may come out in the future. Also reloading supplies for the Fury are supposed to be on their way.

A poster on The Hide put up some pictures from the 2020 Sig catalog that give some more details:





Edit: Whups, didn't realize the catalog photos were already in the TFB article.

I'm interested to see if the case design lives up to the promises, could be very interesting.

On a somewhat related note, Nosler is introducing the 27 Nosler this year as well:

https://www.nosler.com/27-nosler

Also has a 1:8.5 twist, and most interestingly (to me anyway) will be accompanied by the introduction of a 165gr ABLR.

It's a niche cartridge.

.270 WCF performance from a 16" 1:8.5 twist Bbl., short action, and a weight savings.

If you don't need all that, a 24" .270 WCF will do.

But what would the 277 do from a 24'' barrel?

Yes, yes, old -> good, new -> bad, standard THR response, got it.

3,200 fps with a 140gr bullet is what the chart in their catalog says, fully equal to the WSM.

And what’s the recoil and report on a 80k psi short action round gonna be like from a 16” barrel. It’s probably gonna be rough.

That sounds good to me, and I am not a big 270 fan. I think it will do good if they let people know they can fire power psi ammo to not just the 80k stuff, guys have wanted a 270-08 for hears , I'm surprised more are not for this round.

I believe the new powder there using helps with that. I'm sure they worked it out.

Not what I said or meant.

It you neither have nor want the niche specs, the game won't know the difference.

The 16" threaded Fury is clearly meant to be used suppressed, that's where the short barrel really pays off. Suppressed the report will be a non issue, and recoil should be less than an unsuppressed regular .270.

They sent some of the rifles to various gun writers back in October for elk hunts, the reviews that are out are based on running the rifles suppressed, and recoil/blast don't seem to be much of a concern.

I'm very interested in buying a Sig Cross, probably not in .277 Overmatch, but given that the barrels are user changeable, I could see myself giving it a try down the road once more reviews and first hand info are out. I'd like to see a 7mm Fury, but from what I've read, that doesn't seem to be in Sig's immediate plans.

My guess is yes, due to pressure unless you get into funky alloys etc that mean expensive. But not so much an issue for hunting rifles of that caliber and suitable targets.

The interesting thing to me is that the one constant for nearly a century has been the brass case--this is an interesting design to go beyond the limits of the brass case and improve performance by increasing pressure. Not in the market for one but will follow its success or lack thereof. Thanks for posting this.

Barrels, bolts, extractors, ejectors and wallets!

I should imagine that at a military consumption level the loss of brass-on-steel, sacrificial nature of the base would ultimately be very problematic.

Surely, they can't intend a build-up case for a military rifle? The extended costs would be ridiculous - regardless the promises made in the initial enthusiasms.
