9 Best Cartridges for Elk Hunting [Updated 2025]

Most of us don’t live with big bull elk in our backyards. Unless you’re lucky, elk hunting requires extensive planning and significant financial investment.

Elk tags aren’t just expensive. You might not even draw one for your favorite area this season. Chasing bulls is no easy task, either, which is why you can’t trust what might be a once-in-a-lifetime shot to a subpar cartridge.

There are dozens of elk-worthy ammo options on the market. The following are my top picks. When I finally do end up with a Boone and Crockett bull in my crosshairs, I want one of these capable cartridges in my rifle’s chamber.

How We Chose the Best Cartridge for Elk Hunting

Crowning a single cartridge “The King of All Elk” isn’t possible or practical. While a short-action cartridge in a lightweight, fast-handling rifle might be perfect for jumping bulls in thick woods, it isn’t at all suitable for long shots across hundreds of yards of alpine meadow. And while magnum rif;es might be nice for long-range shots, they aren’t particularly fun to haul through rough Western backcountry. (I won’t even mention how brutal they can be on the shoulder.)

With that in mind, this list of the best elk hunting cartridges features entries that are better for certain terrain, situations, hunting styles, and personal preferences than others.

Quick Note: Although some shooters use the words “caliber” and “cartridge” interchangeably, they refer to different things. “Caliber” is the diameter of a projectile (or the bore of the barrel the projectile travels through), and is generally measured in fractions of an inch. The word “cartridge” refers to an entire unit of ammunition: bullet, case, powder, and primer. In this article we discuss the best cartridges for elk hunting.

The Best Elk Hunting Cartridges

The best elk hunting cartridge is the 300 Win Mag. It’s readily available and offers elk hunters plenty of range. However, there are many other quality cartridges capable of ethically harvesting big bull elk.

#1: .300 Winchester Magnum

If you like the .30-06, you’re going to love the .300 Win Mag. This standard-length cartridge offers a smidge more horsepower than the .30-06. That means you can stretch your shots a little farther without sacrificing accuracy, efficacy, or ethics.

Elk have heavier bodies than whitetail or mule deer, so having a little extra oomph behind that .30 cal bullet is a major plus.

The .300 Win Mag pushes a 180 grain SST to a lightning-fast velocity of 3,130 fps. The same bullet leaves the muzzle of a .30-06 at only 2,820 fps. That added cruising speed means the .300 Win Mag bullet drops 10 inches less than the .30-06 at 500 yards.

This flat-shooting cartridge is also available with heavier bullets. That means an even more predictable trajectory, with better wind resistance and downrange striking energy to boot.

To get the best performance out of your hunting rifle, choose .300 Win Mag loads with 200 grain bullets. If you can get your hands on something heavier, all the better.

The .300 WM’s higher-level performance will cost you, however. Rifles chambered in .300 Win Mag are relatively long, heavy, and hard-recoiling. While .300 Win Mag produces a bit heftier recoil than .30-06, its kick is still within what most serious elk hunters can manage.

#2: 6.5 Creedmoor

The 6.5 Creedmoor has been the golden child of target shooters and hunters alike for a relatively short time, as it was only introduced in 2007. In the eyes of its fan base, this cartridge can do no wrong…

…within reason, of course. The 6.5 Creedmoor is often considered a bit of a welterweight when it comes to dropping big bull elk. You’ll definitely want to pick a load with a deep-penetrating, heavy-for-caliber, controlled expansion bullet like the Nosler Partition or AccuBond LR.

You should also place your shots very carefully. Trying to send one of these slender bullets through an elk’s thick shoulder blade could have disastrous consequences for you AND the hapless brute. It just isn’t up to the task. Wait for a good broadside presentation so your bullet can easily plow straight through vitals. The relatively narrow 6.5mm bullet doesn’t leave a whole lot of room for error.

Thankfully, 6.5 Creedmoor’s phenomenal accuracy makes shot placement a breeze. There’s a good reason why this cartridge is a preferred option among elite long-range competitors.

The 6.5 Creedmoor definitely has less recoil than any of the other cartridges on our list. That makes it a smart option for youth, women, and inexperienced elk hunters (who also happen to be experienced shooters).

#3: 6.5 Precision Rifle Cartridge

The 6.5 PRC (and most of its 6.5mm cousins) has the 6.5 Creedmoor to thank for its popularity. Like the 6.5 Creedmoor, the PRC was developed with long-range precision rifle shooting in mind.

The 6.5 Creedmoor and the 6.5 PRC both fire the same bullet; the 6.5 PRC just sends it about 250 fps faster. The high-velocity 6.5 PRC fires a 143 grain bullet at 2,960 fps muzzle velocity; the 6.5 Creedmoor, 2,700 fps. That extra velocity provides some major advantages to elk hunters.

At 500 yards, the 6.5 PRC’s 143 grain bullet drops 8 inches less than the 6.5 Creedmoor’s. It also carries 1,604 ft-lbs of energy when it gets there. That’s respectably more than the Creedmoor’s 1308 ft-lbs that the same distance.

When it comes to harvesting elk, the commonly accepted threshold for striking energy is 1500 ft-lbs. That means the 6.5 PRC still has enough energy to reliably get the job done at 500 yards, whereas the 6.5 Creedmoor hasn’t.

The 6.5 PRC shares many of the 6.5 Creedmoor’s limitations. Neither cartridge has the bullet diameter or weight to handle steep angles or shoddy presentations. Pick a load with a tough, controlled expansion bullet like Hornady’s ELD-X and wait for the textbook broadside shot.

#4: 6.8 Western

Introduced in 2021, Browning and Winchester’s 6.8 Western is a relative newcomer to North American elk hunting. While this ultra-modern cartridge hasn’t exactly caught on quickly, that isn’t due to its performance or potential. It was introduced when going outside was still illegal in many places – an especially dark time, partly because it brought about an ammo shortage. That didn’t exactly boost the 6.8 Western’s popularity.

The 6.8 Western feeds easily and consistently from modern short-action magazines. That means rifles chambered for the cartridge are lighter, more compact, and easier to swing than guns chambered for most of the magnum cartridges on this list.

If you need to tote an elk rifle over miles of rough Montana terrain, 6.8 Western is a good candidate for the job. However, since most major manufacturers aren’t exactly rolling huge numbers of these things off their assembly lines, you might need to order a custom rifle.

Because the 6.8 Western is still basically a newborn cartridge, there haven’t been a ton of quality hunting loads to reach the market. However, if you’re open to handloading, this cartridge has plenty to offer.

Performance is where the 6.8 Western really shines. It slings a 165 grain bullet at an impressive 2,970 fps muzzle velocity with 3,226 ft-lbs of energy. Featuring wider, heavier bullets (165 to 175 grains) than the 6.5s, the 6.8 Western has both a ballistic efficiency and kinetic energy advantage over smaller caliber loads. Those advantages improve its long-distance performance on elk-sized game animals.

#5: 7mm Remington Magnum

The first 7mm Rem Mag cartridges hit store shelves in the 1960s. Thanks to its high-velocity performance and flat-shooting ballistics, elk hunters have been in love with the “Seven Mag” right from the start. However, the cartridge earned an early reputation as a “wounder,” mostly because contemporary bullets were poorly suited to the blistering velocities achieved by the 7mm Rem Mag.

Modern bullet technology has solved the cartridge’s early issues. Today’s 7mm Rem Mag loads feature heavyweight, thick-jacketed bullets that don’t fragment on impact. Instead, they hold on to their weight and deliver deep-driving penetration.

Choose loads with heavy (think 150 grains or higher) controlled expansion bullets engineered for the Rem Mag’s speed. We highly recommend Hornady SST bullets. Stay away from traditional soft points or lightweight bullets designed for whitetail deer.

For a magnum cartridge, the 7mm Rem Mag has tolerable recoil with ballistics that outperform the venerable .30-06 Springfield.

A 162 grain polymer-tipped 7mm Rem Mag projectile clears the muzzle at 3.030 fps. At 500 yards, the 7mm Rem Mag is still zipping along at 2.219 fps and carrying 1.772 ft-lbs of kinetic energy.

That’s plenty of elk-dropping power, and it does it all while dropping 8-½ inches less than comparable .30-06 loads at the same distance.

#6: .30-06 Springfield

Although the topic is hotly debated, .30 has long been considered the best caliber for elk hunting. It should come as no surprise that several .30 cal rifle cartridges made our list.

The .30-06 Springfield is probably the most popular .30 cal cartridge for elk hunting (and deer hunting, for that matter) in America. It has probably been used to fill more elk tags than any other rifle cartridge in history.

Load your elk rifle with heavy 180 grain bullets and you’ll gain higher sectional density (a measure of a bullet’s capacity for penetration), a higher ballistic coefficient, and improved long-range performance.

It is perfectly possible that the “Aught-Six” has killed more elk than all the other cartridges on this list combined. One of the reasons it has seen so much hunting season success is largely due to its long-lasting popularity.

The .30-06 was originally engineered for military use. Many soldiers returning home from both World Wars owed their lives to the cartridge. It comes as no small surprise that they preferred the round they knew best during hunting season.

The same qualities that made the .30-06 effective on the battlefield also make it an effective big game cartridge. The .30-06 is consistently accurate and delivers deadly terminal performance.

While the Aught-Six doesn’t have the head-turning ballistics of the popular magnum cartridges, it delivers plenty of elk-dropping power out to 300 yards. A competent rifleman could stretch that effective range even further.

Modern ammo advancements have improved terminal performance well beyond what our grandfathers witnessed. While soft points were the bullets of choice for generations past, modern bonded projectiles like the Nosler AccuBond or Federal Fusion Tipped provide better accuracy and deeper penetration with less accompanying meat damage.
