In a nutshell it’s a slightly shortened 270 WSM case (0.08” shorter than 270 WSM case) for utilization of high BC very long .277 projectiles in a standard length WSM magazine with 165gr to 175gr weight bullets. Rifles will have faster twist rates in the 1:8 - 1:7.5 range. Can’t really see the benefits unless you are constantly pulling the trigger and bucking wind on game at 700 yards plus. Another reinvention full of intrigue? Probably not, but this is another part of the new wave of rifle/hunting needs being sold to the public.
What’s next? A 6.8 Winchester Magnum on a .300 Win Mag case? No wait, we already have that one. It’s called a .270 Weatherby Magnum....... Happy Trails
Life Member NRA, RMEF, American Legion, MAGA. Not necessarily in that order.
So if you shorten a cartridge so you can use longer bullets why not just seat the bullet to the same overall length in the original case? You can still use the longer bullets unless it has a super short neck in the original cartridge. I would rather have the longer case with powder around the deeper seated bullet rather than lose capacity. Just use the faster twist barrel and be done with it. I guess then though you wouldn’t have a new whiz bang cartridge to sell as the greatest thing since sliced bread

What RossImp said. I’ve been reading on another forum about a guy that rebarreled his 270 WSM to a 1:8 twist barrel. He’s shooting the heavier/longer bullets and is getting good results. I have thought about doing the same thing to mine, but we will see. I asked why Winchester didn’t just start putting 1:8 or faster twist barrels and boy did I hear it. I was told people don’t understand how twist rate works etc., and that was kind of my point. Put a 1:8 twist on the gun to begin with instead of reinventing the wheel. It will allow a person to shoot 130 gr bullets or 175 gr. bullets and no one would probably know the difference. They probably would with 110 gr bullets, but most people aren’t shooting them in. 270 Win or WSM. All I heard was how Joe Blow would load 170 gr bullets in his 1:10 twist 270 Win and get keyholes. This was from the same people saying people don’t understand twist rate and ballistics.
I think this was a natural move as we’ve seen 1:8 twist and faster barrels taking over it seems at least for the newer cartridges that are designed for heavier/longer bullets in other calibers, so why not those in .277. We’ll probably see a new fast twist .257 caliber commercialized soon a well.
If you've got a .270 that you wished would stabilize big bullets and money to burn, why not? The "this is pointless because it overlaps with other stuff" argument could be made about 90% of the cartridges people tout on here.

Not sure of the necessity with a 270 Win, 270 WSM and 270 Wby. A 270 Win w/1:10 twist will shoot the160 gr Partition or 150 A-Frame just fine at elk and moose out to 400-500 yards. If twist bugs you you could simply rebarrel to a fast twist 270 Win LA and get the most out of powder and bullet combo. That 270 Win would easily run with the 6.8 Western using less powder and a handier barrel length for alpine work.

I don’t know if run with is exactly right. With RL26 in a 270 Win I get about 3050 tops, with 26 is my 270 WSM I get 3150 to nearly 3200. Not saying it’s a big deal but the margin only grows as bullet weight goes up and slower powders can be utilized in the larger case.
I like both the WSM and the WCF a bunch but I’m not mad about someone stepping up and putting the 277 Bullets in the running. Heck, it was nearly a 100 years now that Winchester put the 270 WCF on the map, seems like they’re just revamping the old horse a little.
I mentioned this before, it doesn’t do anymore than the 264 or 284 do but so what, it’s a 270 and if it sticks enough it may get Hornady to launch some sleek Bullets for it as well.
Gun manufacturers are doing what custom builders have been doing for years ... pouring a fast twist barrel on it.
It is a real concern for them that if they just charged the twist and made heavy bullets available, that morons would buy that ammo and then bitch about poor performance. Gotta remember educated shooters on forums like this are a SMALL minority of shooters. Idiots would most DEFINITELY buy ammo their gun couldn't shoot. And they'd most certainly publicly bash the ammo matter for making crap ammo their fun can't shoot.
You gotta play to the lowest common denominator. The easiest way? New cartridge with new SAAMI specs.
