Barnes Tipped TSX (TTSX) Bullets .270 cal .277" 130 gr TTSXBT 50/ct

Barnes Tipped TSX (TTSX) Bullets in .270 caliber deliver premium ballistic performance for hunters pursuing large game where one-shot lethality is the standard. These .277" 130-grain bullets combine a polymer tip with Barnes' proprietary Triple-Shock X construction, engineering that increases ballistic coefficient to optimize long-range trajectory while ensuring rapid, controlled expansion upon impact.

The polymer tip initiates expansion by directing energy forward rather than backward into the powder column, a design that separates modern tipped TSX ammunition from traditional lead-core rounds. Upon impact, the bullet's four copper-shank petals expand in a controlled pattern, increasing diameter approximately 50 percent while the solid copper construction maintains deep penetration. The 130-grain weight in .270 Winchester delivers the velocity-to-mass ratio that minimizes time-to-target while maintaining kinetic energy across variable hunting ranges.

Reloaders and shooters who prioritize terminal ballistics over factory ammunition load these bullets for custom rifle loads where precision velocity control and expansion consistency define success. The 50-count box supports dedicated handloaders building matched loads for specific rifle platforms. TTSX ammunition is engineered for hunters who demand repeatable performance across varying shot angles, distances, and game sizes where margin for error is unacceptable.

Barnes maintains tight manufacturing tolerances across its bullet line, meaning dimensional consistency between rounds supports load development repeatability. Hunters working with premium rifles and precision optics select TTSX ammunition specifically for the coupling of ballistic coefficient gains with terminal reliability—two performance vectors that commodity ammunition rarely addresses simultaneously.
