When it comes to elk hunting, not every caliber cuts it. These animals are big, tough, and can cover ground fast. If you’re undergunned, you’re setting yourself up for a long, frustrating blood trail—or worse. So we reached out to folks who’ve been chasing elk for decades: guides, seasoned hunters, and outfitters. Here’s what they actually trust in the field.
.30-06 Springfield
This one’s been around forever, and there’s a reason it keeps showing up in elk camps. With the right bullet, it hits hard and penetrates deep—two things you need for an animal this size.
It’s also super versatile. Whether you’re taking a 100-yard shot in the timber or stretching out to 300 across a canyon, the .30-06 can handle both without fuss. Ammo’s easy to find too.
.300 Winchester Magnum
If you want a little more punch and reach, a lot of pros go with the .300 Win Mag. It carries energy better at longer ranges, which helps on those big open-country shots.
It’s not the softest shooting round, but most folks are okay with a little extra recoil if it means a quicker, cleaner kill. Just make sure your rifle fits you right and you’ve practiced.
7mm Remington Magnum
This one’s a favorite for Western hunters who like flat trajectories and solid knockdown power. It’s fast, accurate, and hits hard without totally beating you up on the bench.
Plenty of elk have dropped to a well-placed 7mm mag. With the right bullet, it’ll punch through shoulder and lungs without blinking. It’s also a great option for covering country with longer shots.
.280 Ackley Improved
This isn’t as common, but those who run it swear by it. The .280 AI offers great ballistics, low recoil, and hits plenty hard for elk. Some say it’s the sweet spot between .270 and 7mm mag.
It’s not something you’ll find at every big box store, so reloading or ordering ahead is a good idea. But in terms of performance, it punches way above its popularity.
.308 Winchester
A lot of folks consider the .308 a little light for elk, but it’s more about shot placement and bullet choice. If you stick to 300 yards and under, the .308 can definitely get the job done.
It’s mild recoiling, easy to find, and works well in lighter rifles—which can matter when you’re hiking through mountains all day. Just use premium bullets and know your limits.
.338 Winchester Magnum
This is for the hunters who want to anchor elk where they stand. The .338 Win Mag is serious business—lots of power, deep penetration, and excellent performance on quartering shots.
It’s not for the recoil-sensitive, and it’s overkill for deer. But if your goal is a short tracking job on big-bodied bulls, this one deserves a look.
.270 Winchester
The .270 gets mixed opinions in elk circles. Some say it’s on the edge, others say it’s dropped more elk than we’ll ever know. The key is using a tough bullet and keeping shots reasonable.
It shoots flat and carries enough energy for heart-lung shots, especially on cows or younger bulls. Not everyone’s first pick, but in practiced hands, it’s proven.
6.5 PRC
The 6.5 PRC is gaining traction fast. It’s flatter shooting than a .308 and has better sectional density than the 6.5 Creedmoor, which helps it hold together on impact.
Many guides are still cautious about it for elk, but with the right bullet and good shot placement, it’s starting to show up more often in the elk woods—and with good results.
.35 Whelen
An old-school thumper that still holds up. The .35 Whelen is basically a .30-06 necked up to .358, and it throws heavy bullets that just hammer elk at close to mid-range.
You won’t get laser-like trajectories, but for thick timber and close encounters, it’s a serious contender. Plenty of guides in grizzly country appreciate the extra wallop too.
.300 PRC
This newer magnum round was built with long-range performance in mind. It’s flatter and hits harder at distance than the .300 Win Mag, with better bullet design and consistency.
It’s a bit much for casual hunters, but guys doing backcountry hunts or shooting across big canyons are starting to favor it. It’s built for precision and power, and it delivers both.
