Are There Specific Laws for Using .338 Winchester Magnum for Elk Hunting?

April 5, 2026

Quick Answer

In the United States, the .338 Winchester Magnum is a widely accepted and effective caliber for elk hunting in many states, but specific laws and regulations regarding its use may vary by state and even by type of land being hunted.

Caliber Restrictions and Permits

The .338 Winchester Magnum is a popular choice for elk hunting in many western states, including Colorado, Wyoming, and Montana. However, some states like Oregon and Washington have specific restrictions on calibers that can be used for hunting elk in certain areas or under certain conditions. For example, in Oregon, the use of .338 Winchester Magnum is prohibited in the state’s “high-risk” areas for elk hunting. Hunters should always check with the state’s wildlife agency for specific regulations and permits required for elk hunting with this caliber.

Bullet Size and Energy Requirements

When using the .338 Winchester Magnum for elk hunting, it’s essential to consider the size and type of bullets being used. For elk hunting, a minimum of 200-grain bullets are recommended, and 250-grain bullets are preferred for their increased kinetic energy and penetration. The .338 Winchester Magnum has a maximum bullet weight of 300 grains, and a minimum muzzle velocity of 2,600 feet per second. Hunters should also consider the use of expansion bullets that are designed to expand upon impact and provide deeper penetration.

Techniques for Successful Elk Hunting

To increase the chances of a successful elk hunt with the .338 Winchester Magnum, hunters should focus on using techniques such as calling and stalking to locate and get close to their quarry. Using a high-powered scope with a minimum magnification of 8x and a reticle that allows for accurate shot placement is also essential. Hunters should also be prepared to make quick and accurate shots at a distance, as elk are known to be wary and may not stay in one place for long.
