Quick Answer
When choosing the right bullet type for .338 Winchester Magnum, consider the weight and type of game you're hunting, such as moose, and select a bullet with sufficient kinetic energy and penetration. For moose hunting, a heavier bullet with a higher BC is often preferred. Look for bullets with a diameter of at least .338 inches and a weight of 225 grains or more.
Weight and Kinetic Energy
When hunting large game like moose, a heavier bullet is often preferred to ensure sufficient kinetic energy at impact. For the .338 Winchester Magnum, consider bullets weighing 225 grains or more. These heavier bullets will provide the necessary energy to expand and penetrate the animal, increasing the chances of a clean kill. Look for bullets with a G1 BC of at least .500, which will maintain their velocity and kinetic energy over longer ranges.
Penetration and Expansion
For moose hunting, penetration is crucial to ensure the bullet can reach vital organs. A bullet with a jacketed soft point (JSP) or a Partition design is ideal, as it will expand upon impact and maintain its weight. The JSP design will penetrate a certain depth before expanding, while the Partition design will separate the core from the jacket, creating a large wound channel.
Ballistic Coefficient (BC) and Velocity
A higher BC will help maintain the bullet’s velocity over longer ranges, increasing its kinetic energy and accuracy. For the .338 Winchester Magnum, a BC of at least .500 is preferred. This will ensure that the bullet stays on target and maintains its energy, even at ranges of 500 yards or more. Consider bullets with a high BC, such as the 250-grain Nosler Partition or the 225-grain Hornady InterLock.
