Once you push past 300 yards, not every cartridge carries its weight. Lighter or slower rounds start to drop quickly and lose energy, which limits both accuracy and effectiveness on target. The cartridges that stay useful are the ones with higher ballistic coefficients, enough velocity to fight drag, and the right bullet designs to hold momentum. Hunters lean on them for shots across canyons, while precision shooters appreciate how they buck the wind. Whether you’re chasing elk in the West or ringing steel plates at distance, these cartridges keep delivering when others start to fade.
.308 Winchester
The .308 Winchester may not be the flattest shooter, but it’s known for carrying momentum beyond 300 yards. With a wide variety of bullet weights—especially in the 165- to 180-grain range—it maintains energy and penetrates well at distance. Hunters have trusted it for decades because it balances recoil, accuracy, and downrange authority.
In practical use, the .308 handles wind reasonably well and doesn’t shed speed as fast as lighter calibers. It’s not a 1,000-yard match round by default, but for hunting medium to large game out to 400 or 500 yards, it continues to perform. The popularity of factory loads makes it accessible, which is why it remains a mainstay in hunting camps.
.30-06 Springfield
The .30-06 Springfield earns its spot because of its versatility and staying power. With 180- or 200-grain bullets, it pushes enough velocity to carry significant momentum well past 300 yards. It doesn’t drop off as quickly as some of the lighter cartridges, and with modern bullet designs, it’s even more capable at distance.
Hunters appreciate that the .30-06 has been tested across every kind of big game in North America. From mule deer to moose, it delivers the authority needed on longer shots without being excessive in recoil. While newer rounds offer higher ballistic efficiency, the .30-06 continues to prove that old designs can still carry serious weight downrange.
6.5 Creedmoor

It bucks wind well and maintains flat trajectories, making it useful for both hunting and long-range target shooting. If you need a cartridge that doesn’t fade after 300 yards, this one delivers with authority.
.270 Winchester
The .270 Winchester is famous for its flat shooting, but it also keeps surprising amounts of momentum after 300 yards. With 130- to 150-grain bullets, it offers both speed and sectional density, allowing it to penetrate effectively even at distance. It’s been a go-to for Western deer and elk hunters for generations.
In the field, the .270 handles long cross-canyon shots with confidence. While it’s not as heavy-hitting as the .300 magnums, it doesn’t shed energy as quickly as smaller calibers. The balance of low recoil, flat trajectory, and downrange momentum is what keeps this round relevant after nearly a century of use.
6.5 PRC
The 6.5 PRC was designed to push the 6.5 Creedmoor’s advantages even further. It offers higher velocity with the same sleek 140- to 147-grain bullets, giving it superior momentum retention past 300 yards. The added speed means less drop and better wind performance without punishing recoil.
Hunters see the PRC as a step up for elk and other larger game where the Creedmoor may run out of steam at distance. Precision shooters value how consistent it remains past 1,000 yards. In terms of carrying energy downrange, the 6.5 PRC is one of the best modern cartridges available today.
.280 Ackley Improved
The .280 Ackley Improved has earned a reputation for long-range performance. Using high-BC 7mm bullets, it maintains excellent momentum and energy beyond 300 yards. Its velocity sits between the .270 Winchester and 7mm Remington Magnum, offering a sweet spot of speed and manageable recoil.
In hunting, the .280 AI is valued for being versatile. It can handle mule deer, elk, and even moose when paired with the right bullet. Shooters appreciate that it doesn’t burn barrels as quickly as some magnums but still carries authority at distance. For a cartridge that flies under the radar, it does exceptional work past 300 yards.
.338 Winchester Magnum
The .338 Winchester Magnum is known for carrying devastating energy at long range. With bullets often in the 225- to 250-grain range, it starts with massive momentum and doesn’t give it up easily. At 300 yards and beyond, it’s still packing the kind of power needed for the largest North American game.
Hunters who pursue moose, elk, or big bears often choose the .338 Win Mag for its downrange punch. While recoil is significant, the payoff is knowing you’re carrying a cartridge that doesn’t run out of steam. For those hunting in rugged country where shots can stretch long, this round inspires confidence.
