Which bullet weight is optimal for the Barnes TSX in .308?

Understanding Monolithic Bullets

The Barnes TSX is a popular choice among hunters and shooters due to its monolithic design, which features a single piece of tungsten alloy. This design provides exceptional penetration and expansion, making it suitable for large and medium-sized game. The TSX’s monolithic construction also allows for consistent performance, even at high velocities.

Choosing the Right Bullet Weight

When selecting a bullet weight for the Barnes TSX, it’s essential to consider the intended use and game size. For most hunting applications, a 150-160 grain bullet weight is optimal, as it strikes an ideal balance between penetration and expansion. This weight range allows for deep penetration and a large wound channel, making it suitable for taking down larger game. For example, a 150 grain Barnes TSX can penetrate over 12 inches of ballistic gelatin at 100 yards, while still expanding to 1.5 times its original diameter.

Ballistic Performance Considerations

When shooting the Barnes TSX, it’s crucial to consider the ballistic performance. The optimal velocity range for the TSX is between 2600-2800 feet per second, which allows for maximum expansion and penetration. At velocities above 2800 fps, the TSX may over-expand, while velocities below 2600 fps may result in inadequate expansion. To achieve optimal performance, shooters should aim for a muzzle velocity of around 2700 fps, which can be achieved with a suitable barrel length and ammunition combination.
