What are Regulations Around Using .338 Winchester Magnum for Elk?

April 5, 2026

Quick Answer

In North America, the .338 Winchester Magnum is a suitable caliber for elk hunting in many states and provinces, but specific regulations vary by region. For example, in Wyoming and Montana, it's a popular choice for elk hunting, but in some areas, like Alaska, a minimum caliber of .30-06 is required. Hunters must check local regulations before using this caliber.

Caliber Suitability

The .338 Winchester Magnum is a versatile caliber suitable for elk hunting, offering a balance of power, accuracy, and recoil. Its 250-300 grain bullets typically deliver muzzle velocities of 2,600-2,900 feet per second, providing the kinetic energy needed to humanely harvest elk. In comparison, the minimum recommended kinetic energy for elk is 1,200 ft-lbs, and the .338 Winchester Magnum’s 2200 ft-lbs exceeds this threshold.

Hunting Techniques

When using the .338 Winchester Magnum for elk hunting, it’s essential to choose the right bullet type and configuration. A 250-grain bullet with a high ballistic coefficient, such as the Nosler AccuBond or the Hornady InterBond, is a good choice. These bullets maintain their velocity and energy over long distances, allowing for accurate shots at 300-400 yards. Additionally, using a muzzle brake or suppressor can reduce recoil and make follow-up shots easier.

Regional Regulations

Before using the .338 Winchester Magnum for elk hunting in a specific region, hunters must check local regulations regarding minimum caliber requirements, projectile restrictions, and any other specific guidelines. For instance, in Alaska, hunters must use a minimum caliber of .30-06, while in Wyoming and Montana, the .338 Winchester Magnum is a popular choice. Hunters should also familiarize themselves with local bag limits, season dates, and any additional restrictions to ensure compliance.
