The race for new space on the ammunition shelves at your favorite gun shop is a fast and furious one, with manufacturers launching new cartridges each year with the hopes of grabbing a small piece of this big pie. The long-range market has been particularly lucrative recently and with Hornady’s launch of the 6.5 PRC in 2018 and the 7 PRC in in 2022, it didn’t leave much room for Winchester/Browning, but they found a spot right in the middle with the 6.8 Western. At one time, metric cartridges were all but a guarantee of failure in the American cartridge market but with the interest in the long-range game, came an expectation of metric cartridges. Plain old imperial measurements just weren’t as good in consumers’ minds. And thus, was born a new .277 caliber cartridge, the 6.8 Western.
What Is the 6.8 Western?
It is based on Winchester’s 270 WSM, arguably the most successful of the Winchester Short Magnum line of cartridges. In fact, it really isn’t that different. The case was shortened slightly from 2.100 inches to 2.020 inches, and the shoulder is set back 0.081 inches, but the overall length of the cartridges remains the same. This was done to allow the use of heavier bullets with a higher ballistic coefficient in the 6.8 Western while still meeting the specifications for a short-action cartridge. Heavier-weight bullets were the one limiting factor for 270 cartridges, with 145 grains being at the upper limit before the 6.8 Western came on the scene. The 6.8 Western is capable of handling bullets up to 175-grain, but the real magic isn’t in the cartridge but rather in the rifles chambered in it.
6.8 Western Ballistics & Twist Rates (Why 1:8 and 1:7.5 Matter)

Prior to the 6.8 Western, most 270s were equipped with barrels with a 1:10 or 1:9 twist and were unable to stabilize heavier .277 bullets. Winchester and Browning rifles are equipped with a 1:8” and 1:7.5” twist, respectively, to help stabilize these longer, heavier bullets. You could accomplish the same thing by re-barreling a 270, but the smart thing that Winchester did was ensure the 6.8 Western fit into a short action, a desirable trait for western mountain hunters.

6.8 Western Ammo vs. 270 WSM: Key Differences
Like it’s parent cartridge, the 270 WSM, the 6.8 Western does post some impressive velocities, with the 165- and 170-grain bullets leaving the muzzle at over 2,900 feet per second (fps) and the 175-grain at over 2,800 fps. This is a proprietary cartridge for Winchester and Browning, but more recently, a handful of other niche manufacturers are chambering rifles in it. Ammunition is still primarily limited to Winchester and Browning, with a couple of niche manufacturers also offering ammunition. Bullets, too, are a bit limited for handloaders. Proprietary cartridges have been a kiss of death for many newcomers, and to this point, the 6.8 Western is holding its own in the marketplace, but time will tell if it survives in the long run.
Let’s take a look at a few of the more popular rifles chambered in 6.8 Western.
