Ask ten elk hunters for the best caliber for elk and you will get ten answers. The truth is that several modern cartridges do the job extremely well, and the right choice depends on how far you shoot, how much recoil you tolerate and how much rifle weight you are willing to carry. Here we compare four of the most popular options, all available in Seekins Havak rifles.
What Makes a Good Elk Cartridge?
Elk are large, tough animals, often shot at longer distances than deer. A good elk cartridge pairs a heavy, well-constructed bullet with enough velocity to retain energy and expand reliably at your maximum range. Just as important: you must be able to shoot it accurately. A cartridge you flinch with is worse than a milder one you shoot well.
7mm PRC
The 7mm PRC for elk has become one of the most popular choices since its 2022 launch. It shoots long, high-BC 175 to 180 grain bullets with a flat trajectory and less recoil than a .30 caliber magnum. For most elk hunters it is the sweet spot between power and shootability.
300 PRC
The 300 PRC is designed around very heavy, very long .30 caliber bullets. It excels at extreme range and carries tremendous energy. The trade-off is more recoil and more expensive ammunition.
300 Win Mag
The 300 Winchester Magnum has been a proven elk cartridge since 1963. When comparing 300 PRC vs 300 Win Mag, the PRC handles the longest bullets better at long range, while the Win Mag offers wider ammunition availability and lower cost. Inside 600 yards, the elk will not know the difference.
6.8 Western
The 6.8 Western for elk is a clever design: heavy .277 bullets from a short magnum action. It delivers impressive downrange energy with recoil closer to a standard cartridge, and it fits in lighter, shorter rifles.
Quick Comparison
| Cartridge | Recoil | Long-range energy | Ammo availability |
|---|---|---|---|
| 7mm PRC | Moderate | Excellent | Good |
| 300 PRC | Heavy | Outstanding | Fair |
| 300 Win Mag | Heavy | Excellent | Excellent |
| 6.8 Western | Moderate | Very good | Fair |
Choosing Your Elk Hunting Rifle
A great elk hunting rifle is light enough to carry up a mountain and stable enough to shoot well when you are breathing hard. The Seekins Havak Element and Havak Slam are built for exactly that, while the Pro Hunter 2 offers longer barrels for maximum velocity.
Our Pick
For most hunters, the 7mm PRC is the best all-around elk cartridge today. If you want maximum reach and can handle recoil, choose the 300 PRC. If ammunition availability matters most, the 300 Win Mag is still a superb choice. Always check your state’s hunting regulations, available through your state wildlife agency and resources like the Rocky Mountain Elk Foundation.
