Quick Answer
Bullet expansion is crucial for .338 Federal elk hunting, as it helps to ensure a quick and humane kill. A well-designed bullet that expands upon impact can transfer kinetic energy to the elk, resulting in a swift and humane harvest. Proper bullet expansion also increases the chances of a clean shot.
Bullet Selection for Elk Hunting
When selecting a bullet for elk hunting with a .338 Federal, it’s essential to choose a design that expands consistently at the velocities typical of this cartridge. The Sierra GameKing 200-grain and the Barnes TSX 200-grain bullets are popular options that have proven effective for elk hunting. These bullets are designed to expand at around 2,200-2,300 feet per second, which is the average velocity of a .338 Federal rifle.
Understanding Bullet Expansion
Bullet expansion is a critical factor in elk hunting, as it helps to transfer kinetic energy to the animal and ensure a quick kill. A bullet that fails to expand can result in a slow and painful death, which is unacceptable. When selecting a bullet, look for designs that have a high coefficient of friction (BCF) and a controlled expansion. The BCF is a measure of the bullet’s ability to resist deformation and maintain its velocity. A bullet with a high BCF will expand more consistently and penetrate deeper into the elk’s body.
Field Performance Expectations
When hunting elk with a .338 Federal, it’s essential to have realistic expectations about the bullet’s performance. At ranges beyond 300 yards, bullet expansion can be inconsistent, and penetration may be reduced. This is because the bullet has lost some of its kinetic energy due to air resistance and has begun to deform. To compensate for this, hunters should aim for a spot just behind the elk’s front shoulder, where the bullet can enter the body and expand quickly. This increases the chances of a clean shot and a swift harvest.
