338 win mag ballistics chart 338 winchester magnum load data

The .338 Winchester Magnum, commonly referred to as the .338 Win Mag, is a powerful and versatile rifle cartridge that has become a favorite among hunters and shooters. Its impressive ballistics make it an excellent choice for taking down large game at extended ranges. To better understand the capabilities of this cartridge, it's essential to examine its ballistics chart. In this article, we'll delve into the key aspects of the .338 Win Mag's performance, exploring its velocity, trajectory, and kinetic energy at various distances.

1. Muzzle Velocity

The .338 Win Mag's muzzle velocity is approximately 2,900 feet per second (fps) with a 200-grain bullet, which is a common weight for hunting applications. This high initial velocity provides a flat trajectory and helps to mitigate wind drift, making it an excellent choice for long-range shooting. As the bullet travels downrange, its velocity decreases, but it still maintains a significant amount of kinetic energy, ensuring effective expansion and penetration upon impact.

2. 100-Yard Performance

At 100 yards, the .338 Win Mag's velocity has dropped to around 2,600 fps, and its kinetic energy has decreased to approximately 3,200 foot-pounds (ft-lbs). Despite this reduction, the cartridge still delivers a significant amount of energy, making it more than capable of taking down medium-sized game such as deer or elk. The .338 Win Mag's performance at this distance is still impressive, with a relatively flat trajectory and minimal wind drift.

3. 200-Yard Performance

As the .338 Win Mag's bullet travels to 200 yards, its velocity has decreased to around 2,400 fps, and its kinetic energy has dropped to approximately 2,800 ft-lbs. At this distance, the cartridge begins to show signs of slowing down, but it still delivers a considerable amount of energy. Hunters can expect effective expansion and penetration from the bullet, making it suitable for larger game such as moose or bear.

4. 300-Yard Performance

At 300 yards, the .338 Win Mag's velocity has decreased to around 2,200 fps, and its kinetic energy has dropped to approximately 2,400 ft-lbs. While the cartridge's performance has slowed down, it still maintains a relatively flat trajectory and delivers a significant amount of energy upon impact. This makes it an excellent choice for long-range shooting, especially when paired with a high-quality rifle and optic.

5. Trajectory

The .338 Win Mag's trajectory is relatively flat, with a bullet drop of approximately 10 inches at 300 yards. This is due to the cartridge's high initial velocity and the bullet's aerodynamic design. When sighted in at 200 yards, the .338 Win Mag's trajectory is nearly flat, with a rise of around 2 inches at 100 yards and a drop of around 10 inches at 300 yards.

6. Wind Drift

Wind drift is a critical consideration when shooting at extended ranges, and the .338 Win Mag is no exception. At 300 yards, a 10 mph crosswind can cause the bullet to drift around 10 inches. However, when using a high-quality rifle and optic, shooters can compensate for wind drift by adjusting their aim point, ensuring accurate shots even in windy conditions.

7. Kinetic Energy

The .338 Win Mag's kinetic energy is a critical factor in its effectiveness as a hunting cartridge. At the muzzle, the cartridge delivers approximately 4,000 ft-lbs of energy, which decreases to around 2,400 ft-lbs at 300 yards. This significant amount of kinetic energy ensures that the bullet expands effectively and penetrates deeply, making it an excellent choice for taking down large game.

8. Bullet Weight and Type

The .338 Win Mag can be loaded with a variety of bullet weights and types, ranging from 150 grains to 250 grains. The most common bullet weights for hunting are 200-220 grains, which offer an excellent balance between expansion and penetration. Shooters can choose from a range of bullet types, including Nosler Partition, Barnes TSX, and Sierra GameKing, each with its unique characteristics and advantages.

9. Effective Range

The .338 Win Mag's effective range is approximately 400-500 yards, depending on the shooter's skill level and the rifle's quality. At these distances, the cartridge still delivers a significant amount of kinetic energy, making it suitable for taking down large game. However, shooters must be aware of the cartridge's limitations and adjust their aim point accordingly to compensate for bullet drop and wind drift.
