Sunday GunDay: 6.8 Western — New Cartridge, New Rifles
Winchester and Browning have introduced the new 6.8 Western, a new .277-caliber cartridge designed for long-range hunting. The new 6.8 Western is a high-capacity cartridge with a modern 35-degree shoulder, optimized for a conventional short action. The 6.8 Western is VERY similar to the existing .270 WSM. It shares the same 0.535″ rim diameter, and the same 0.277″ bullet diameter, however the 6.8 Western’s case length is slightly shorter. The .270 WSM has a 2.100″ case length, while the new 6.8 Western has a 2.020″ length. That’s just 80 thousandths shorter. Both cartridges, the 6.8 Western and .270 WSM, share a 35° shoulder, so in fact, the 6.8 Western is VERY close to the existing .270 WSM, just .080″ short. With a 1:8″ twist, the 6.8 Western should be able to shoot bullets up to 175 grains.

In designing this new cartridge, Winchester wanted WSM performance in a slightly shorter case: “The key feature… was to shorten up that shoulder, shorten up the OAL of the cartridge so we could get longer, sleeker, heavy-for-caliber bullets to really drive the G1 BC higher and higher, to get the flattest possible trajectory.” Winchester claims that the 6.8 Western is the “largest [cartridge] on the market to fit into lighter, short-action rifles like the Winchester Model 70, Winchester XBR, and Browning X-Bolt Pro”. That’s a bit deceptive, since the .300 WSM, with a 0.2100″ case length, will fit in many of those rifles with most bullets. Oh well — there’s always some marketing hype.
6.8 Western — High-BC Bullets, Good Knock-Down Power, Tolerable Recoil
What is the real advantage of the new 6.8 Western? Fundamentally it can be loaded with heavier, higher-BC bullets than a 6.5 PRC, while having less recoil than a .300 WSM (with most bullets). (But the same can be said of the older .270 WSM.) WideOpenSpaces.com states that with the 6.8 Western “recoil is much lower than the .300 Win Mag, .300 PRC, and the .300 WSM cartridge. At the same time, the 6.8 is said to deliver more energy to the target than a 6.5 PRC [or] 6.5 Creedmoor[.]” Winchester is even claiming more downrange energy than a 7mm Remington Magnum.

“When people think of the perfect long-range rifle cartridge, they want many key features — good precision, flat trajectory, large down-range energy, and manageable recoil.” — Keith Masinelli, Winchester

Why Develop a New Hunting Cartridge So Similar to the .270 WSM?
With interest in long-range hunting growing rapidly, engineers at Winchester and Browning sought a solution that could offer magnum performance with a modern high-BC projectile, yet chamber in a short action rifle for shorter bolt-throw and less weight. The 6.8 Western was “designed to be capable in any big-game hunting scenario and a great fit for those who enjoy long-range target shooting”. For the 6.8 Western, the designers basically shortened the .270 WSM case to allow for longer bullets (with the same cartridge OAL limits), and possibly make the case a bit more efficient.
The First 6.8 Western Rifles from Browning and Winchester
Browning X-Bolt Pro in 6.8 Western
Browning will release a light-weight, X-Bolt Pro rifle chambered for the 6.8 Western. This will have a 26″ barrel with 1:7.5″-twist, so it should be able to shoot all the high-BC .277-caliber bullets. With a carbon-reinforced stock, this rifle is relatively light-weight — just 6 lbs., 12 ounces before optics. The rifle has a 3-lug bolt with 60° bolt lift. Trigger adjusts from 3-6 pounds, fine for a hunting rifle. According to Wide Open Spaces, the barrel and receiver are finished with Tungsten Cerakote to protect the rig in harsh weather conditions. On Browning’s website, the Browning X-Bolt in 6.8 Western has a $2,469.99 MSRP. At that price, it may make more sense to buy a used X-Bolt rifle and re-barrel it.
“The 6.8 Western cartridge brings a new perspective to long-range hunting and shooting,” said Ryan Godderidge, Senior VP of Sales, Marketing, and Firearms for Browning. “It provides magnum-level performance in our short action rifles, giving the shooter highly effective down-range energy, even at longer ranges, while allowing for a lighter-weight platform.”
Winchester Model 70 in 6.8 Western
Winchester will release a Model 70 chambered for the 6.8 Western. It will have a 24″ stainless barrel, stainless action with 3-round hinged floor-plate internal magazine. Wide Open Spaces reports: “Right now, it appears the Model 70 Extreme Weather MB is the first 6.8 Western that will roll off their factory floors. The stock is composite with a Pachmayr Decelerator recoil pad. At 44.25″ overall, this rifle is shorter than the Browning X-Bolts, but weighs slightly more at seven pounds even.” Listed MSRP is $1,599.99 for this new 6.8 Western Model 70.

OK Great another rifle you can’t get ammo for.
Will be a sure fire success??????
I like new things, but for the first time I feel like we really jumped the shark. A short 270WSM, come on. Really?
And chambered in one of the longest magazine short action rifles (the win70), which could run a 270WSM with a long bullet already with a faster twist barrel.
I’m getting tired of all the new cartriges that are pretty much the same as another cartrige. Not sure why ammo and rifle companies are pushing new products right now when they can’t even keep product on the shelves.
I have always been interested in new cartridges but it’s getting crazy lately with cartridges so similar that do the same thing. 0.80 shorter case? For a hunting round does it really matter if the long bullet is seated 0.80 deeper…NO. How about the 7mm Rem short mag? Better LR cartridge for big game or at least as good and aside from some LR target shooters…it’s almost extinct. This 6.8 Western will go nowhere.
I have not interest in this cartridge. In fact, nothing has come down the pike recently that has caught my attention. Instead, I have been building bolt guns on older cartridges like the 358 Winchester. Maybe it’s just nostalgia but the older stuff has worked for generations and I have no need to reinvent the wheel.
The pricing on these factory rifles is getting into the custom rifle range. No thanks! No logic to this chambering at all. Bring on the WSM brass!
The max OAL for this thing is 2.995″. It clearly fits the M70 and X-bolt “short actions”. What other “short actions” would it fit?
Thanks

To me for once someone actually thought about a cartridge. im glad we can start using the .277 caliber to its potential. next we need something like this done with the .257 caliber.
