Quick Answer

Yes, state regulations for 338 Federal elk hunting vary by state, so it's essential to check with the specific state's wildlife agency for information on maximum cartridge case length, bullet weight, and other restrictions.

State-by-State Regulations

Elk hunting regulations for the .338 Federal vary significantly across different states. For example, in Wyoming, the rifle cartridge must have a minimum case length of 1.92 inches, whereas in Colorado, there is no specific case length requirement for the .338 Federal. However, Colorado does specify a minimum bullet weight of 150 grains. In Idaho, the .338 Federal is allowed for elk hunting, but there is a restriction on the type of bullet that can be used. Hunters should consult the relevant state’s wildlife agency for the most up-to-date information on regulations.

Understanding the Ballistics of the .338 Federal

The .338 Federal is a versatile cartridge suitable for hunting elk in various terrain conditions. Its ballistics offer a good balance between range and kinetic energy transfer. The cartridge has a muzzle velocity of approximately 2,700 feet per second and a muzzle energy of around 2,800 foot-pounds. This makes it effective for taking down elk at distances of up to 400 yards. To maximize the effectiveness of the .338 Federal, hunters should use the right bullets and shooting techniques. For example, using a bullet with a high ballistic coefficient, such as the 200-grain Nosler AccuBond, can improve accuracy and range.

Hunting Techniques for Elk with the .338 Federal

Hunting elk effectively with the .338 Federal requires a combination of knowledge, skill, and experience. First, hunters should understand the habitat and behavior of the elk they are hunting. This includes knowing the best locations to set up a stand or ambush, as well as how to read elk tracks and sign. In terms of shooting techniques, hunters should aim for the vitals, which include the lungs, heart, and liver. Aiming for the shoulder or off-center shots can result in a longer recovery and more suffering for the animal. Hunters should also be aware of their surroundings and follow all necessary safety protocols when shooting.
