TSX .224 55gr Flat Base 223/5.56 (Per50) Barnes Bullets continues expanding its popular line of TSX Bullets. An improved version of the original all-copper X Bullet, the TSX features a series of grooves cut into its shank. The grooves significantly reduce pressures, allowing safe higher velocities. TSX bullets virtually eliminate copper fouling, while delivering outstanding accuracy and performance. Containing no lead, the TSX features 100-percent copper construction. On impact, the specially engineered nose cavity expands into four razor-sharp copper petals that slice through game, producing massive hydraulic shock. These all-copper bullets are known for deep-driving penetration and double-diameter expansion. In addition to being exceptionally accurate, they retain virtually 100-percent of their original weight after impacting game. BarnesUnleaded. Unfailing. Unbeatable.
