Is the 6.8 Western the Most Underrated New Hunting Cartridge?

American hunters have a love affair with .270 hunting cartridges that dates back over a century. In 1925, Winchester introduced the .270 WCF, a cartridge that is now known the world over as the .270 Winchester. It didn’t take long for hunters to learn to love the cartridge because it offered a flat trajectory coupled with mild recoil, and one of the round’s most vocal champions was Jack O’Connor, certainly one of the most popular gun writers of his time.

Winchester has tried to recapture a bit of the .270 magic, first in 2002 with the launch of the .270 Winchester Short Magnum (WSM) and later in 2020 with the release of the 6.8 Western. The .270 WSM was designed to be an efficient short-action cartridge that offered magnum-level ballistics, but the 6.8 Western took the design a step farther by developing a .270 hunting cartridge that utilized low drag, high-BC bullets.

In case you’re wondering, 6.8 is the metric equivalent of .277-inches, the diameter bullets used in the .270 Winchester and .270 WSM. Why Winchester switched to the metric equivalent isn’t clear–perhaps to grab hold of some of the 6.5mm magic? Whatever the reason, the 6.8 Western had the goods to make it a successful modern hunting cartridge. It utilizes a 2.020-inch case with a 35-degree shoulder angle and has a cartridge overall length of 2.955-inches. The cartridge was designed with ample powder capacity and would fit in short action hunting rifles.

But what truly sets the 6.8 Western apart from other .270 cartridges is that it was designed from its inception to handle heavy-for-caliber, high ballistic coefficient bullets. Long range shooters have known for years that low drag bullets with high BCs performed exceptionally well in target matches, in large part due to their improved aerodynamics. A bullet that retains velocity and deflects wind makes it easier to hit targets at extended ranges, and that’s one of the driving factors behind the success of cartridges like the 6.5 Creedmoor.

Modern .270 Rifle

What Winchester effectively did was offer hunters a .270 rifle that could take advantage of high BC bullets. The only problem, however, is that there aren’t a lot of high BC .277-inch projectiles. Winchester partnered with companies like Nosler and Sierra to source high-BC bullets specifically for the launch of the 6.8 Western, projectiles such as Nosler’s .277-inch 165-grain AccuBond Long Range and Sierra’s 175-grain Tipped GameKIng, both of which have a G1 ballistic coefficient over .600. The AccuBond bullet is available in Winchester’s Expedition Long Range ammunition line and boasts a muzzle velocity of 2,970 feet per second while the Tipped GameKing bullet is loaded in Browning’s Long Range Pro Hunter line and attains a muzzle velocity of 2,830. Muzzle energies are also impressive. The Browning factory load manages 3,123 foot-pounds at the muzzle and the Winchester achieves 3,226 foot-pounds. That’s a few hundred foot-pounds less than a .300 Winchester Magnum with 180-grain bullets.

Impressive as the 6.8 Western is at the muzzle, this cartridge really shines at extended ranges. The AccuBond 6.8 Western load clings to 1,856 foot-pounds of energy at 500-yards, which is almost 300 more foot-pounds of punch than you’ll get at that distance from a 7mm Remington Magnum and 200 more foot-pounds than a 180-grain .300 Win Mag at that distance. The 6.8 Western loads also shoots three-inches flatter at that distance than the 7mm Rem Mag when both rifles are zeroed at 200 yards, and the 6.8 Western does all this with recoil that is similar to the 7mm Rem Mag and 16% less than the .300 Win Mag. Very impressive.

Ballistics are essential when assessing a cartridge, but they don’t tell the entire story. Rifle and ammo availability, competition from other cartridges, and even release dates can all impact a cartridge’s survival. Here’s a look at the pros and cons of the 6.8 Western

What the 6.8 Western Does Well

Balance: The 6.8 Western sits in the sweet spot between the 6.5mms and 7mms. Cartridges like the 6.5 PRC, 6.5 RPM, and 6.5 Creedmoor have proven to be great performers, but they fire bullets in the 140-grain range, not the 160 and 170-grain projectiles you’re getting from the 6.8 Western and that makes the 6.8 Western more suitable for large game like elk and adds to the cartridge’s versatility.

Despite its impressive ballistics the 6.8 Western is not a difficult cartridge to shoot well. Yes, it does recoil more than the popular 6.5s in similar-weight guns, but it produces less recoil than the newer 7mm PRC and any of the .300 Magnums. Even in lightweight guns the 6.8 is manageable, and when you consider its impressive terminal performance alongside its modest recoil the 6.8 Western is one of the most balanced hunting cartridges on the market.

Design Elements: The 6.8 Western was well designed. Its 35-grain shoulders with relatively straight body taper make it efficient and allow it to push heavy-for-caliber bullets to impressive velocities while still fitting in a short action rifle. 6.8 Western rifles most often utilize 1:7.5 or 1:8 barrel twists to stabilize those heavy-for-caliber bullets, and accuracy from the rifles I’ve tested has been excellent. I had a chance to test the Browning X-Bolt 2 Hunter rifle at the NRA Whittington Center range in New Mexico to 600 yards and I was thoroughly impressed by the sub-MOA performance. That’s the third 6.8 Western I’ve shot, and every one of them produced similar accuracy.

Action Size: The ability to stuff all this performance into a short action cartridge is one of the 6.8’s great strengths. Because it can be built in short-action rifles the 6.8 Western is lighter than comparable rifles by about five or six ounces. That may not seem like much weight savings, but when you’re hunting at thin-air elevations and every step is taxing, saving on rifle weight is a real benefit. Light weight rifles coupled with manageable recoil and excellent terminal performance combine to make the 6.8 Western one of the best mountain rifle cartridges to come along in decades.

Field Performance

I don’t have broad-reaching evidence of the 6.8’s terminal performance on game, but I do have some experience with the cartridge in the field. I carried it on a New Mexico elk hunt in the fall of 2024 and found that the cartridge performed very well. We heard bugling from a steep canyon and slipped along a finger ridge to get in place above the action. The draw below us was choked with densely growing pines and we saw only patches of elk–an ear here, a backline, a leg. But the bull kept screaming and I knew that he would eventually step into the clearing. When he did I sent the 165-grain AccuBond into the chest at 220 yards. The bull staggered at the impact, faltered, and then disappeared from view. We found him piled up 20 yards from where I’d shot.

My experience was not unique with the 6.8 Western. Fellow writers like Tom Beckstrand and Colton Heward have had similar experiences with big game while using the 6.8. The cartridge doesn’t recoil as much as the .30s, but it certainly hits hard and isn’t grossly oversized for game like antelope and whitetail deer. Every hunter I’ve spoken with who carried a 6.8 Western has had good experience with the cartridge.

Where the 6.8 Struggles

Timing of Release: Silly as it may sound, the 6.8 Western suffers from bad timing. It was announced in 2021, which also happened to be the tail end of the COVID pandemic. With vaccine and mask mandates still dominating the news cycle the 6.8 didn’t get the love it deserved. What’s more, there were record firearm sales during COVID and, as a result, there were massive ammo shortages. It was hard to find .270 Winchester ammo for a while as manufacturers tried to keep up with skyrocketing demand for rounds like 9mm and .223. It wasn’t great timing to release a new cartridge with fairly limited ammunition options and the 6.8 Western suffered as a result. When gun owners can’t buy ammo for the rifles they already have they aren’t interested in purchasing something entirely new.

To make matters worse, just a year after the 6.8 Western arrived Hornady launched their 7mm PRC which was seen as a step up in power and performance compared to the 6.8. Hunters who were warming to the idea of a high BC .270 offering were suddenly faced with a new 7mm alternative that offered more energy.

Rifle, Ammo, and Bullet Availability: Ammo, rifle, and bullet availability are still important factors when purchasing a new gun. The 6.8 Western has been chambered in several nice rifles including Browning’s X-Bolt 2, Winchester’s Model 70 and XPR, and various guns from Seekins, Savage, Christensen, and other manufacturers over the years, but it can’t match the number of rifles chambered in 6.5 or 7mm PRC. Retailer MidwayUSA currently lists 26 6.8 Western rifles available as compared to 84 different 6.5 PRC and 89 7mm PRC models. The same site lists 10 6.8 Western loads compared to 47 6.5 PRC loads and 31 7mm PRC loads. There are also fewer high-BC .277-inch bullets than .264 or .284 options.

The silver lining for the 6.8 Western is that there are some very good ammo options available. Winchester’s 162-grain Copper Impact and 165-grain AccuBond Long Range loads have earned a solid reputation with hunters, and so has Browning’s 175-grain Sierra GameKing Tipped load. Barnes recently added 6.8 Western to their Reserve line and offer it with a 155-grain LRX bullet. Barnes’ Dale Evans recently used that load to take a mountain goat, one of the toughest animals in North America.

Long-Range Target Following: Target shooting and hunting were once seen as different disciplines, but with so much overlap long-range competition shooting has a major impact on the success or failure of a cartridge. The various PRC were launched as precision rifle cartridges (hence the name) designed for long-range performance that crossed the boundary into the hunting market. The 6.8 Western, by contrast, was viewed as a hunting cartridge.

Does it matter? Yes. Should it? Probably not–at least not to hunters. The 6.8 Western is a capable long-range round, for what it’s worth. You can shoot it beyond 1,000 yards, but there are very few competition-style rifles available in 6.8 Western. I’ve seen a lot more tactical or hybrid tactical/hunting rifles in the field in recent years, and most have been chambered in one of the various PRC cartridges. So even though the 6.8 Western cartridges has the numbers to make a long-range range it isn’t viewed that way by many hunters and shooters.

The Competition From Existing Rounds: The truth is someone who hunts whitetails and hogs at ranges to 300 yards or so won’t see much appreciable difference between their old .270 and a new 6.8 Western. Western hunters who climb mountains and shoot hundreds of yards across windy canyons will likely notice a difference between the two, but for many hunters there simply isn’t a need to replace their existing rifle with something new.

I’m a gun guy and I have had the opportunity to hunt in the western U.S., so the 6.8 Western intrigues me. It’s flatter trajectory and better aerodynamics make it better suited to some conditions, and I like that recoil is quite tolerable, but for many hunters who already own a 7mm Rem Mag, .300 Win Mag, or .30-06 (and that’s a large percentage of the hunting population) the 6.8 may not offer anything that they don’t feel they get from their existing gun.

Should I Buy a 6.8 Western?

New cartridges rarely exist on an island, and with so many good centerfire hunting cartridges today the 6.8 Western faces stiff competition. But it has a lot to offer and it’s well designed. It’s also capable of tackling any game from antelope to elk and moose even at extended ranges, and it’s available in rifles with short actions to help reduce weight and overall length. It’s certainly one of the best western/mountain rifle chamberings in my mind, and my experience with the cartridge has been very positive. One gun writer’s approval does not seal the fate of a cartridge (unless, of course, you’re Jack O’Connor and that cartridge is the .270 Winchester), but I'll tell you that the 6.8 Western is a very good hunting cartridge that’s versatile and accurate. Now we must wait and see how it holds up in the future.
