Barnes Triple-Shock X (TSX) 375 Caliber 300 Grain Lead-Free Hollow Point Flat Base Bullets - Box of 50

The Barnes Triple-Shock X (TSX) 375 caliber bullets represent a purpose-built choice for handloaders pursuing large game at distance or up close. Built entirely from copper rather than traditional lead-core construction, these 300-grain hollow point rounds are engineered to perform consistently across the varied shot angles and distances real hunting demands. Whether you're loading for elk, moose, or dangerous game, TSX bullets deliver the kind of reliability that separates a clean harvest from a long tracking job.

What sets these rounds apart is their expansion mechanism: upon impact, the hollow point opens into four razor-sharp petals that cut deep into vital tissue and bone. The engineering is specifically designed to retain 100 percent of the bullet's original weight during expansion, meaning energy transfer and penetration remain predictable and devastating through heavy muscle and skeletal material. For hunters who've experienced the frustration of unreliable expansion or core/jacket separation, that weight retention is a genuine game-changer.

Reloaders will appreciate the flat base design, which simplifies seating in most 375 caliber dies. Barnes recommends a seating depth between 0.03 and 0.07 inches from the ogive, depending on your specific rifle and magazine constraints—work up within your rifle's preferences for best accuracy. Each box contains 50 bullets, giving you a solid foundation for a hunting load or test batch before committing to larger quantities.

Frequently Asked Questions

What game can I hunt with 375 caliber TSX bullets?

The 375 caliber, paired with 300-grain TSX bullets, is traditionally chambered in rifles suited to large and dangerous game, including elk, moose, and African species. The combination of weight retention and deep penetration makes these bullets well-suited to that purpose. Always confirm your specific rifle's intended use and check local hunting regulations.

Do I need special dies to reload these bullets?

No—TSX bullets use a standard flat base profile, so they work with conventional rifle reloading dies. Barnes recommends seating between 0.03 and 0.07 inches from the ogive; start at the length that works for your specific rifle and magazine, then refine based on accuracy testing.

Are these bullets lead-free?

Yes. These TSX bullets are solid copper throughout, with no lead core. They're compliant with lead-free ammunition mandates in jurisdictions where that matters for hunting.

What's included in the box?

Each box contains 50 finished TSX bullets, ready to seat into your reloaded cartridges.
