Barnes Triple-Shock X (TSX) 7mm 140 Grain HPBT Lead-Free Bullets - Box of 50

Barnes Triple-Shock X (TSX) 7mm 140 grain HPBT lead-free bullets deliver serious terminal performance for hunters who demand reliability on big game. Built from 100 percent copper, these hand-loading rounds are engineered to expand on impact with four razor-sharp petals that cut deep through dense bone and tissue. If you're reloading ammunition for hunting, TSX bullets are built to maximize energy transfer and ensure clean, ethical kills.

What sets TSX bullets apart is their solid construction and weight retention. Unlike traditional copper-jacketed designs, the monolithic copper build means no jacket/core separation—the bullet stays together through and through, retaining 100 percent of its original weight. That translates to deeper penetration and more reliable expansion on elk, deer, and similar game at hunting distances.

Precision matters when you're handloading. Barnes recommends seating depth between 0.03 to 0.07 inches from the rifling for optimal accuracy, though the exact distance will vary by rifle. This flexibility lets you fine-tune your load to your specific firearm and find the sweet spot for your hunting or range loads. Each box contains 50 bullets, giving you plenty of component for load development or a full season afield.

Frequently Asked Questions

Are Barnes TSX bullets really lead-free?

Yes. Triple-Shock X bullets are manufactured from 100 percent copper with no lead content, making them compliant with lead-free ammunition regulations in all states and jurisdictions.

Will these 140 grain 7mm bullets work in my rifle?

TSX bullets are sold as reloading components for handloaders, not as factory ammunition. They are designed for 7mm caliber rifles. Always consult your rifle's manual and any applicable reloading manuals to confirm compatibility and safe loads for your specific firearm.

What seating depth should I use?

Barnes recommends seating these bullets 0.03 to 0.07 inches from the rifling, but the optimal distance depends on your individual rifle. Start with load development to find the most accurate seating depth for your firearm and load combination.

Why do TSX bullets retain 100 percent of their weight?

Because they are monolithic copper projectiles, there is no jacket-to-core separation. The entire bullet remains intact and in one piece, which supports deeper penetration and more consistent terminal performance on game.
