The New 6.8 Western is a Versatile Big-Game Hunting and Long-Range Shooting Cartridge from Browning and Winchester

If you want to introduce a successful new big-game cartridge these days, it’s got to be the fastest, hottest, hardest-hitting, new load ever created, right? Well, actually, no. Browning and Winchester’s new 6.8 Western works off the concept that if you take a long, sleek, heavy bullet and fire it at a reasonable velocity, you’ll get just as good (or better) down-range performance as ultra-fast bullets that are less streamlined. And, you’ll get that performance with less recoil.
So their engineers took a .270 Winchester Short Mag. case and lowered the shoulder to allow for a longer bullet in a short-action rifle. That also meant less propellant loaded into the round.
“The challenge in 6.8 Western was all about balance,” says Kyle Masinelli, director of New Product Development for Olin Winchester. “It was the balance of taking a parent case in .270 WSM and actually taking away powder capacity to make it more powerful down range. It seems counterintuitive, but that was exactly what was accomplished. If we compare it to our top performing 270 WSM cartridge, the 6.8 Western has 10 percent less propellant, but has 12 percent more energy at 500 yards. It seems that we cheated physics somewhat, but we really just used it to our advantage by optimizing case capacity and bullet weight. Less propellant also equates to less muzzle blast.”

And there’s no doubt that Browning and Winchester are touting this new cartridge as a long-range hunting and target shooting load to try to capture some of the excitement created by the 6.5 Creedmoor and 6.5 PRC. With the 6.8 Western’s heavier bullets, Winchester says it’s bringing 16 percent more energy than the 6.5 PRC at 500 yards and 67 percent more energy than the 6.5 Creedmoor. Winchester is claiming 24 ft-lb of recoil, which is about the same as a 7mm Rem. Mag. (but again, with more energy at long ranges).
Both Browning and Winchester are offering ammo in this new cartridge and building rifles for it. For starters, Winchester will load 165-Grain Accubond Long Range bullets and Browning will load 175-Grain Sierra Tipped Game King bullets. Eventually they plan to introduce loads with the Winchester Ballistic Silvertip and a Match BTHP. Last fall, Tyler Freel and I both had the opportunity to test the two bullets they’re launching this cartridge with and we got to see real-world performance on a handful of big-game animals. Here’s what we found. —AR
Browning 175-Grain Sierra Tipped Game King in 6.8 Western
Just days before my moose hunt, I opened a pre-production box of ammunition as the fumes from the delivery truck still hung in the air. I plucked one of the cartridges out of the box and rolled it around in my hand, looking at the 6.8mm (.270 cal) 175-grain Sierra Tipped Game King bullet. That’ll do, I thought.

Sierra is breaking into new .277″ territory with this bullet, as previous chamberings did not have fast enough twist rates to stabilize such a long bullet in that caliber. This new Tipped Game King requires a tighter twist rate—1:8 in the Winchester rifles or 1:7.5 in Browning rifles (lighter .270 bullets are adequately stabilized in a barrel with a 1:10 twist). This new Sierra bullet has a G1 B.C. of .617. It’s designed to carry energy at long range, but built to hold together for close shots on big animals.
I took a quick trip to the local rifle range to zero my gun. I was shooting a Browning X-Bolt Western Hunter, and as usual, I immediately removed the muzzle brake. With my very first shot, I was pleasantly surprised at the mild recoil of the cartridge, even though it was pushing that new 175-grain bullet at a recorded 2835 fps. I zeroed the rifle at 200 yards and the factory loads averaged just under 2-inch, 5-shot groups at that range.
There’s plenty of folks who will argue that any .270 caliber cartridge is too small for moose. They’re wrong. Alaska Yukon moose are big, but they aren’t very difficult to kill. They have big bones and thick hides, but they also have gigantic lungs, and although they usually don’t drop immediately (even with big cartridges), they aren’t indestructible the way some people make them out to be. Now, I should point out that the particular load I was using was definitely more than “just another .270”. With this new 175-grain bullet, at the velocity I measured, from an energy standpoint it would really sit between a .30-06 and .300 Win. Mag. shooting 180-grain bullets. But the 6.8 Western has a better B.C., and better sectional density than a .308 diameter bullet. I had no doubts in the cartridge, but I was curious about bullet performance, which besides shot placement, is the most critical factor when it comes to putting down big animals.
A couple weeks later, I held the rifle steady atop a tripod as a bull grunted his way through a stand of burnt timber toward my soft cow calls. My buddy and I had been hunting for eight days, we’d passed up several small bulls, and he killed a dandy. I needed meat for the winter, and at this point in the hunt, I didn’t have the luxury of passing another bull. I tracked the moose through my riflescope, only about 100 yards away now, waiting for an opening through the patchwork of charred spruce trees. I moaned out a cow call and the bull stopped, with a hole about the size of a basketball exposing the back of his front shoulder. I shot and the bull spun and took a few steps. I quickly shot again, and then once more. Finally, with only his shoulder exposed, I fired a fourth shot, dropping him. A volley like this might seem excessive or indicative of less-than-lethal performance, but that’s just how moose are, they rarely go down immediately (even when the first shot is lethal). Especially in such tight quarters, its best to keep shooting in case your first shot wasn’t as good as you thought. When we walked up to the bull, I found that my first shot had been perfect, with another a few inches away, also through the lungs. The third shot had hit a branch and ricocheted into the bull’s antler. The fourth shot punched square through the scapula.

I was happy to see that both lung shots were complete pass-throughs. It seemed that the bullets held together well—even at relatively short-range—because I didn’t find any petals or shrapnel in the body cavity. The final shot had completely broken the scapula, but didn’t yield the kind of catastrophic meat damage on the impact side that you’d expect from a bullet coming apart. In fact, I recovered the bullet under the hide on the back side, and it still weighed 102 grains, a weight retention of 58 percent. Considering the range, velocity, and what it impacted through (a bull moose’s shoulder), I was impressed. —T.F.
Winchester 165-Grain Accubond Long Range in 6.8 Western
I received my 6.8 Western ammo in nondescript preproduction box last summer, about a month before heading to Alaska for a blacktail deer and mountain goat hunt. And just like Freel, I was shooting a Browning X-Bolt Western Hunter, and mine was topped with a Leupold VX-3i 3.5-10mm scope.
The Accubond Long Ranges are bonded, boattail bullets with polymer tips. As their name implies, they’re designed to expand reliably at long ranges and lower velocities, (down to 1,300 fps.) The 165-grain ABLRs have a muzzle velocity of 2970 fps and a G1 BC of .620. From the bench I was able to average just over 1-inch, 5-shot groups at 100 yards.

On the range the rifle handled and functioned nicely, as you would expect from an X-Bolt, and I felt confident in the rifle and cartridge going into my hunt. From there, I proceeded to put the platform through the wringer.
Southeast Alaska was on pace to set rainfall records by the time I arrived in August. And just a few hours after stepping off a plane in Juneau, I was hiking up through the Tongass forest’s old-growth timber after blacktail deer. By the time we reached the alpine, the rifle and optic were soaked, and they stayed that way for the next several days. My hunting partner Bjorn, an experience southeast Alaska outdoorsman, carried a hefty Ruger .338 Win. Mag.—his go-to rifle in bear country. Half the time he used it as a walking stick in the steep, slick terrain. The X-Bolt weighed right around 7.5 pounds and was much easier to carry in the mountains, though I still used it as a walking stick from time to time and managed to slip and fall just as often as Bjorn.

On the last day of our hunt we finally spotted a blacktail buck on a hillside below us. He was about 200 yards away with a doe, on a steep downhill angle. As I got set up to shoot, the doe slipped into the woods but the buck paused at the treeline, quartering away from us hard, looking toward his doe. It was now or never. My shot took him squarely through the hip and he tumbled into a strip of timber below. Bjorn found him piled up just about 150 yards downhill. The bullet had passed clear through the deer.

Later in the fall I took the 6.8 Western to northern Wisconsin for the deer season opener. Just a few hours into opening morning I spotted a nice buck following some does through a stand of thick popple about 90 yards away. He disappeared for a few moments but I could still hear him crunching through the leaves. I spotted a flash of antler and then I gave a loud bleat and the buck stopped in a shooting window for just long enough.

At my shot, he bounded about 30 yards and crashed down. The bullet entered behind his front shoulder and buried into the far shoulder. I found it, perfectly mushroomed, just beneath the hide on the offside—excellent performance at close range.

Close-range and mid-range performance is key for any new “long-range” hunting bullet. Because no matter what we’re shooting, we’re going to get as close as possible. —AR
