Barnes TSX 7mm 140-Grain Boat Tail Bullets

Barnes TSX: The Hunter's Choice for Ethical Big Game Hunting

The Barnes Triple-Shock X (TSX) represents a fundamental shift in bullet design philosophy. Built entirely from copper rather than traditional lead-core construction, these 140-grain projectiles deliver the penetration and reliability serious hunters demand.

What Makes TSX Bullets Different

All-Copper Construction Unlike conventional bullets, TSX rounds contain no lead core. This design choice delivers measurable advantages: 28% deeper penetration than comparable lead-core bullets, combined with 100% weight retention upon impact. For hunters pursuing dense-boned game, this combination proves decisive.

Engineered Ring Technology Precisely cut rings along the bullet shank function as relief valves during the firing sequence. This innovation produces three significant benefits:

• Improved accuracy and tighter shot groups
• Reduced chamber pressures, allowing for higher velocity loads
• Minimal copper fouling in your barrel

Controlled Expansion Upon impact, the TSX expands in a controlled manner, creating four razor-sharp petals. This design ensures deep cutting capability through vital organs and bone structure while maintaining the bullet's integrity throughout the wound channel.

Practical Guidance

For optimal accuracy, seat these bullets 0.03 to 0.07 inches off the lands, adjusting based on your specific rifle's chamber. This flexibility allows handloaders to fine-tune performance for their particular firearm.

The Bottom Line

If you demand a bullet that penetrates reliably, expands predictably, and delivers ethical one-shot performance on big game, the Barnes TSX deserves serious consideration.
