Quick Answer
Barnes TTSX bullets are compatible with a wide range of calibers, but optimal performance is achieved in cartridges with muzzle velocities between 2500 and 3000 feet per second, such as the 6.5 Creedmoor, .280 Ackley Improved, and .308 Winchester.
Caliber Combinations for Maximum Performance
The Barnes TTSX bullet excels in cartridges with high muzzle velocities and moderate to high ballistic coefficients. A 6.5 Creedmoor chambered rifle with a 140-grain Barnes TTSX bullet can achieve velocities of up to 2900 feet per second, making it a highly effective choice for hunting medium to large game. The 6.5 Creedmoor’s flat trajectory and high ballistic coefficient also make it an excellent choice for longer-range shots.
Other Notable Caliber Combinations
Other notable caliber combinations for Barnes TTSX bullets include the .280 Ackley Improved, which can achieve velocities of up to 3000 feet per second, and the .308 Winchester, which can achieve velocities of up to 2800 feet per second. These cartridges offer a good balance between velocity and recoil, making them suitable for a wide range of hunting applications. When loading these cartridges with Barnes TTSX bullets, it’s essential to maintain a consistent powder charge to ensure optimal performance.
Considerations for Loading and Shooting
When loading and shooting with Barnes TTSX bullets, it’s essential to consider the rifle’s twist rate and barrel length. A faster twist rate (1:7 or 1:8) is recommended for cartridges with high muzzle velocities, such as the 6.5 Creedmoor, to ensure stable bullet flight. Additionally, a shorter barrel length (24 inches or less) may be beneficial for cartridges with high muzzle velocities, as it can help reduce barrel stress and improve accuracy.
