I always carried at least 13 - 30 round mags, two bandoliers of ammo and two canteens of water when going anywhere in the bush.
I still have some of the mag pouches and magazines.

If the 277 fury does what is advertised, there would no need to double tap. So, there's a chance it will do the same or more with somewhere over half as many rounds needed...making the round count needed less and somewhat less weight to pack. Or, pack as many rounds as before, 200?, and have more capability to destroy the target.

During testing does DoD drop the rifle muzzle first in the mud then try to fire the weapon? I'm guessing @ 80k not a good idea.
There will be no reduction in rounds down range for suppressive fire when your maneuver element is assaulting the objective up to its LOA. It's not precision shooting out there.
And this is why I expect it to end up in a DMR role and 5.56 to still remain a large part of the rounds sent. I'd guess 99%+ of rounds shot are for suppressive fire and not really aimed AT an individual. In that role, 5.56 still makes more sense to me out to 500 yards or so. The vast majority of lead airmail in war is to keep an enemies head down, not kill them directly.
So I'm one of those guys loading 277 bimetal cases necked up then down to 308 and 6.5 Creedmoor. The Creedmoor got over 3124 fps average with 140 gr bullets, and over 3000 fps with 150 gr SMK in a 24" barrel. The 308 has some improvements also, but it's a 30" 8 twist Bartlein barrel so I used another 9 twist 22" Bartlein. The 6.5 Creedmoor is a factory rifle and I ordered a 26" 7.5 Twist Bartlein for it ...
I could order a 277 reamer ...but this is an expensive experiment already. Ran through a hundred rounds, check throat erosion and lug set back...it's okay so far. Even pulled bullets on some loads. This bimetal case has promise for a bunch of cartridges. Useful powders seem limited, as is my willy-nilly testing, and it seems logical that barrels will erode faster, so I fired some in fast secession, and check, as this barrel will be replaced, on this sacrificial rifle. I do not recommend doing this...and no manufacturer will stand behind this kind of abuse of their products, as expected. Sig does not recommend reloading these cases or stand behind their 277 rifles with reloads. If you could even find one in 277....I have reloaded some 3 times, in testing so far.
Not recommended by anyone, play here at your own risk. Pressures and its signs are different as are powder reactions to the SS case head as less thermal energy is transfered to the SS case head and more to the powder charge.. I do not believe you can blow a primer out of this SS case head, without destroying the rifle, so don't go there... For most I'd recommend them to buy the brass Lapua cases in these calibers, they work well at slightly elevated pressures.

Can you describe DMR role? Please.

Designated marksman rifle aka sniper
A squad designated marksman, they usually carry weapons more suitable for slightly longer range engagements, and would be the guys most likely to be shooting to kill, not mainly to suppress. In the past they've generally used "accurized" versions of the m16, and possibly sr25 .308 and some other semi autos.
Someone who has actually been there and done that would be more likely to be able to fill in what they do in practice, but that's the gist of a DMR to the best of my knowledge.
Can't let that one slide. Designated marksman is not a sniper. No fieldcraft training. Solely marksmanship.

Thank you for correcting me. My understanding was synonymous.
I just wanted everyone to know, I picked up my Sig Cross 277 Fury just the other day. I got it at the Sig Experience Center in Exeter, NH. They said I was the first person to purchase one at their store.
Anyway, I spent yesterday, cleaning and lubing, mounting my scope and bipod. Monday is my range day, so I will be sighting in my new 5-25 Vortex Venom scope and breaking in the barrel.
I will let you all know how she shoots.

Does it have a 20" 1-10 barrel like on their website?
Curious why they did that when it's supposed to be a short barrel cartridge. And why they didn't want modern 277 bullets to be fired from it, given the SAAMI spec they developed calls for a 7 twist.
Yes it has a 20" barrel and weighs 7.1 lbs. To be honest, I have no idea why the 20" vs. the 16". I never bothered to ask.
