Is there a significant difference in energy transfer with TTSX vs TSX?

April 5, 2026

Quick Answer

The TTSX bullet offers improved energy transfer due to its AccuBond bullet technology, while the TSX provides good expansion but with slightly less consistent results.

Monolithic Bullet Design

The TSX and TTSX bullets are both designed with a solid copper jacket, allowing for deeper penetration and weight retention upon impact. However, the AccuBond design in the TTSX bullet features a bonding process that combines the lead core with the copper jacket, creating a more uniform density and reducing the potential for lead separation during expansion.

Energy Transfer and Expansion

The TTSX bullet’s AccuBond technology enables more efficient energy transfer through the target, resulting in a deeper and more consistent wound channel. In testing, the TTSX has shown a 10-15% increase in retained weight compared to the TSX, indicating a more effective transfer of kinetic energy. This is particularly valuable when hunting larger and more challenging game.
