Barnes Triple-Shock X (TSX) 270 Caliber 140 Grain Lead-Free Hollow Point Boat Tail Bullets - Box of 50

Barnes Triple-Shock X (TSX) bullets in 270 caliber deliver the all-copper construction and controlled expansion performance that serious hunters rely on for ethical, reliable big-game takes. At 140 grains, these hollow point boat tail projectiles are engineered to expand predictably on impact while retaining weight for deep penetration through heavy bone and tissue—the combination that separates a clean kill from a wounded animal. If you're reloading ammunition for deer, elk, or other medium to large game and want ammunition that performs, TSX rounds have earned their reputation among hunters who won't compromise on terminal ballistics.

The design centers on four razor-sharp petals that open on contact, creating a wide wound channel while the bullet stays together and drives forward. Lead-free construction makes these rounds compliant with regulations in areas requiring non-toxic ammunition, without sacrificing the stopping power hunters expect. Each box of 50 gives you plenty of rounds to load, sight in, and put to work in the field. Because terminal performance matters most when your tag is on the line, TSX bullets reward the reloader who pays attention to accuracy—the manufacturer notes that seating depth between 0.03 and 0.07 inches from the lands will yield the best results, though your specific rifle may prefer a different spot within that window.

Handloaders value Barnes bullets for their consistency and the control that custom ammunition brings to hunting season. Whether you're fine-tuning a load for a new rifle or sticking with a proven recipe that has never let you down, these 270 140-grain TSX rounds are built for the hunter who understands that precision ammunition is an investment in success.

Frequently Asked Questions

Are Barnes TSX bullets good for hunting deer and elk?

Yes. TSX bullets are designed for medium to large game, with the 140-grain 270 caliber version suitable for hunting deer, elk, and similar-sized animals. The controlled expansion and weight retention provide the penetration needed to reach vital organs through heavy bone and muscle.

What does lead-free mean, and do I need to use lead-free bullets?

These bullets are made entirely from copper instead of a lead core, which makes them compliant with non-toxic ammunition regulations required in certain states and hunting areas. Check your local hunting regulations to determine whether non-toxic rounds are required where you hunt.

How do I use the seating depth range when reloading?

The 0.03 to 0.07-inch seating depth range from the lands is the manufacturer's general guidance for best accuracy. Your specific rifle may prefer a different seating depth within this window, so it's best practice to develop your load by testing several depths and measuring which gives the tightest group.
