Barnes Triple-Shock X (TSX) 270 Caliber 150 Grain Lead-Free Hollow Point Flat Base Bullets - Box of 50

Barnes Triple-Shock X (TSX) bullets in 270 caliber, 150 grain are a solid choice for hunters building their own ammunition who demand reliable, hard-hitting performance on big game. These lead-free hollow point rounds are built from 100 percent copper, engineered to expand reliably on impact and generate four razor-sharp petals that cut deep through vital areas. If you're reloading for a 270 Winchester or similar cartridge and want ammunition that delivers both accuracy and terminal performance, TSX bullets have earned their reputation in the field.

What sets the Triple-Shock X apart is its design philosophy: controlled, predictable expansion paired with 100 percent weight retention. That means the bullet stays together through bone and heavy tissue rather than fragmenting, maximizing energy transfer and penetration on elk, deer, and other game at hunting distances. The flat base design is straightforward to load and seat, and Barnes recommends experimenting with seating depth between 0.03 to 0.07 inches off the lands to find what your specific rifle prefers—a small detail that often makes the difference between good groups and great ones.

Each box contains 50 bullets, so you'll have plenty for load development, practice, and hunting season. Whether you're fine-tuning a new rifle or restocking your reloading bench, these 150-grain TSX rounds give you a versatile, proven bullet that works across typical hunting ranges.

Specifications

Frequently Asked Questions

What caliber rifle will these bullets work in?

These are 270 caliber bullets, so they're designed for 270 Winchester and other 270-diameter rifle cartridges. Always verify your specific caliber and rifle specifications before loading.

Are these bullets suitable for hunting, or just target shooting?

These are purpose-built hunting bullets. The hollow point design and controlled expansion make them well-suited for taking big game at typical hunting distances. The 150-grain weight works across a range of 270 cartridges commonly used for deer, elk, and similar game.

Do I need to adjust seating depth, or can I just load them?

Barnes recommends testing seating depth between 0.03 and 0.07 inches off the lands to find what your specific rifle shoots most accurately. Since different rifles have different chamber dimensions, a little load development yields better results—and often tighter groups.

Are these lead-free bullets more expensive or harder to reload?

The copper construction doesn't make them harder to reload than conventional bullets; the flat base design loads just like standard ammunition. The lead-free aspect means they're compliant in restricted areas and environmentally responsible, with no special reloading technique required.
