Elk are tough. They’re big-boned, broad-chested, and don’t bleed out easy. If your caliber doesn’t carry enough weight, energy, or range, you’re setting yourself—and the animal—up for trouble. Hunters who’ve been there, done that, know which calibers leave too many follow-up shots and long blood trails. It’s not always about how much recoil you can handle—it’s about having enough power where it counts. If you’re heading to elk camp, these calibers are better left at home.
.223 Remington

You’ll hear it from someone who’s never hunted elk—it’s “all about shot placement.” Sure, in a perfect world. But elk aren’t coyotes. The .223 doesn’t have the mass or energy to punch through thick hide, muscle, and bone reliably.
Even the best bullets in this caliber struggle to deliver ethical kills on an animal that can weigh over 700 pounds. It’s not fair to the elk, and it’s not smart for you. There are better tools for the job that won’t leave you tracking for hours.
.243 Winchester

The .243 has taken elk, no doubt. But for every success story, there’s one about a wounded bull that disappeared over a ridge. It’s on the ragged edge of being “enough,” and bullet selection has to be perfect.
You’re also giving up energy and penetration, especially past 200 yards. If you catch a shoulder or misjudge the angle, things go sideways fast. Plenty of folks use it for deer—but elk aren’t deer. If you’re going to chase elk, step it up a notch.
6.5 Creedmoor

This one’s going to ruffle feathers. Yes, the 6.5 has solid ballistic performance and shoots flat. But the elk doesn’t care about your group size—it cares about energy on target. And that’s where the Creedmoor falls short.
At longer distances, you’re losing velocity and impact power fast. It can work with perfect conditions and the right bullet, but elk camp usually throws curveballs. When you’ve got unpredictable wind, brush, and steep angles, bigger is safer. Leave the Creedmoor for antelope.
.30-30 Winchester

The old lever gun has filled a lot of freezers—but elk hunting isn’t the kind of job it does well anymore. With limited velocity and a rainbow trajectory, the .30-30 makes clean shots hard to pull off at any real distance.
It hits a wall fast when you stretch past 150 yards. Most elk hunters today expect longer shots, and this round just isn’t built for that. Unless you’re calling them in tight in heavy timber, you’re better off with something flatter and harder-hitting.
7.62x39mm

This cartridge is basically a .30-30 with a different coat of paint. It’s great in an AK for hogs or deer at close range—but elk hunting demands more than that. The bullet weight and velocity combo just doesn’t bring the energy you need.
You’ll also run into issues with bullet construction. A lot of the ammo out there isn’t designed for big game. And with accuracy being hit or miss, it’s not something experienced hunters trust when there’s a bull in the scope.
.22-250 Remington

This one’s a flat shooter and a favorite for varmint work—but that’s where it should stay. The bullets are too light, and they tend to fragment instead of penetrate. That’s a terrible combo when you’re facing a mature elk.
Even with a well-placed shot, you’re not likely to reach the vitals with the force needed to drop an animal that size. Hunters who’ve tried it usually walk away with regrets—or long days of tracking and empty hands. Elk deserve better.
.25-06 Remington

The .25-06 is a sweet shooter for deer, but it’s marginal for elk. It doesn’t have the bullet weight to handle shoulder shots, and a quartering bull can soak up a lot of energy before going down. That’s not what you want in rugged country.
Some experienced marksmen can make it work with premium bullets and perfect conditions. But it’s still pushing the limits of what most would call ethical. When things go wrong—and they do—you’ll wish you brought something heavier.
5.56 NATO

Some folks try to argue that the 5.56 is close enough to a .243 or that modern bullet tech makes it viable. That’s wishful thinking. The cartridge was designed for fighting, not for taking down game the size of a small horse.
It lacks the bullet mass and terminal energy to consistently get through the vitals. Sure, it’ll poke a hole. But elk hunting isn’t about poking holes—it’s about dropping an animal quickly and cleanly. The 5.56 isn’t up for it.
.270 WSM

This one surprises people. The problem isn’t power—it’s the way it burns barrels and can be finicky with consistency. Some rifles just don’t group well with factory loads, and if your rifle won’t hold tight groups, you’re in for trouble.
You’ve also got limited ammo availability compared to the .270 Win or .30-06. If something goes wrong at camp or in the field, you’re stuck. The round’s got speed, but that doesn’t matter if your rifle can’t shoot it well. Elk hunting’s not the place to gamble.
.300 Blackout

This caliber is all the rage in the AR crowd, especially suppressed. But elk hunting? It’s a hard no. Subsonic loads don’t carry enough energy, and even the supersonic stuff is built for close-range use, not deep penetration.
You’re giving up everything that makes a good elk round—range, accuracy, and terminal performance. If you’re going into the woods with a .300 Blackout hoping to take down an elk, you’re asking for a mess. Stick to deer or hogs with this one.
