Barnes Triple-Shock X (TSX) 375 Caliber 270 Grain Lead-Free Hollow Point Flat Base Bullets - Box of 50

Barnes Triple-Shock X (TSX) 375 caliber bullets are engineered for hunters who demand maximum terminal performance and 100% weight retention on big game. These 270 grain, lead-free hollow point rounds are constructed entirely from copper and designed to expand on impact, creating four razor-sharp petals that cut deeply through dense bone and tissue. Whether you're handloading for dangerous game, large African species, or magnum rifle hunting situations, TSX bullets deliver the penetration and controlled expansion serious hunters depend on for reliable one-shot kills.

Built on a flat base design, these bullets combine the advantages of lead-free construction—meeting regulations in all 50 states and beyond—with proven stopping power. The all-copper construction ensures the bullet retains its full original weight through the animal, maximizing momentum transfer and tissue damage rather than leaving weight in the wound channel. This weight retention is critical for consistent, ethical kills on large, tough game at field distances.

Reloaders will appreciate the precise engineering that makes TSX bullets forgiving in the handloading process. Seating depth typically ranges from 0.03 to 0.07 inches off the lands depending on your specific rifle, so you have room to fine-tune for optimal accuracy in your chamber. Each box contains 50 bullets ready to load, and their reputation for consistency makes load development straightforward even for hunters new to big-game handloading.
