Barnes TTSX 264 Cal bullets are a premium copper-alloy option for reloaders building ammunition for medium to large game at extended distances. Built entirely from copper rather than lead-core construction, these 120-grain spitzer boat-tail projectiles deliver reliable expansion and penetration across a range of hunting scenarios. The polymer tip design improves ballistic coefficient, supporting flatter trajectories and better energy retention downrange—a real advantage when hunting at distance or pursuing tougher game where shot placement matters.

Upon impact, the TTSX design initiates controlled expansion, with four distinct petals that increase the bullet's diameter by approximately 50 percent. This aggressive opening transmits energy efficiently while maintaining adequate penetration. The boat-tail profile reduces drag and helps group shots tighter at distance, making these bullets a solid choice for hunters who reload their own ammunition and want to maximize accuracy and terminal performance in the field.

Lead-free construction makes TTSX bullets compliant with regulations in jurisdictions restricting traditional lead ammunition. Reloaders should seat these projectiles between 0.030 and 0.070 inches off the lands, depending on firearm geometry and overall load development. Like all reloading components, final load development and accuracy testing in your specific rifle is essential before field use.

Frequently Asked Questions

Are Barnes TTSX bullets lead-free?

Yes. These bullets are manufactured entirely from copper, making them compliant with lead ammunition restrictions in certain hunting areas and jurisdictions.

What caliber rifles can I use these bullets in?

These are 264 caliber / 6.5mm bullets. They are designed for rifles chambered in cartridges that accept 6.5mm projectiles (such as 6.5 Creedmoor, .260 Remington, and similar calibers). Always verify compatibility with your specific rifle and cartridge before loading.

What game are these bullets suitable for?

The 120-grain TTSX is engineered for medium to large game hunting. Suitability depends on your specific cartridge, hunting distance, and regional game. Consult ballistic tables and hunting regulations for your intended application.

How should I seat these bullets in my reloads?

Barnes recommends seating between 0.030 and 0.070 inches off the lands, depending on your rifle's chamber geometry. Proper load development and accuracy testing in your specific firearm is essential before field use.
