Quick Answer
The right weight for TTSX bullets depends on the caliber, velocity, and the desired expansion pattern. A general rule of thumb is to choose a bullet weight that matches the calibers' typical hunting weight, but this can vary depending on the specific application.
Caliber-Specific Bullet Weights
When choosing the right weight for TTSX bullets, consider the specific caliber and its typical hunting weight. For example, in .243 Winchester, a 90-grain TTSX bullet is a common choice, while in .308 Winchester, a 150-grain TTSX bullet is more typical. In larger calibers like .30-06 Springfield, a 180-grain TTSX bullet is often preferred.
Velocity and Expansion
Velocity plays a crucial role in determining the optimal weight for TTSX bullets. At lower velocities, a heavier bullet may be required to achieve sufficient expansion, while at higher velocities, a lighter bullet can be effective. For example, in a .300 Winchester Magnum, a 180-grain TTSX bullet may be preferred at lower velocities, while a 150-grain TTSX bullet may be more effective at higher velocities.
Bullet Weight and Kinetic Energy
The kinetic energy of the bullet is also an important consideration when choosing the right weight for TTSX bullets. In general, a heavier bullet will have more kinetic energy than a lighter bullet, but this can also affect the bullet’s expansion pattern. For example, a 200-grain TTSX bullet may have more kinetic energy than a 180-grain TTSX bullet, but it may also be more prone to overspreading.
