Barnes Triple-Shock X (TSX) Lead-Free Bullets - 45-70 Caliber, 250 Grain, Flat Nose, Box of 20

Barnes Triple-Shock X (TSX) lead-free bullets in 45-70 caliber deliver the controlled expansion and weight retention that serious big-game hunters demand. Built entirely from copper rather than lead, these 250-grain flat-nose projectiles are engineered to expand reliably on impact while staying together through bone and heavy tissue—the combination that turns shots into clean, ethical kills. Whether you're handloading for your Marlin, Sharps, or modern lever-action, TSX bullets give you the performance edge without the environmental cost of traditional lead ammunition.

The signature four-petal expansion design maximizes energy transfer and tissue destruction while maintaining structural integrity. Barnes achieves this through their proven copper construction, which allows for thinner jacket walls and faster, more dramatic opening compared to traditional jacketed bullets. For hunters working thick cover or taking longer shots at elk, moose, or other heavy game, that combination of rapid expansion and deep penetration makes a meaningful difference in the field.

Handloaders appreciate TSX bullets for their consistency and the extra attention Barnes demands during seating. The manufacturer recommends experimenting with seating depths between 0.03 and 0.07 inches to find your rifle's sweet spot—a small variable that can unlock impressive accuracy once dialed in. Each box contains 20 bullets, so you'll have plenty for load development and hunting season prep.

Frequently Asked Questions

Are Barnes TSX bullets legal for hunting in states with lead-free ammunition requirements?

Yes. These bullets are made from 100 percent copper with no lead content, meeting the requirements of California and other jurisdictions that mandate non-lead ammunition for hunting.

What rifles work well with 45-70 TSX bullets?

The 45-70 caliber is common in Marlin and Winchester lever-action rifles, Sharps single-shots, and some modern bolt-actions. The flat-nose profile is particularly suited to lever-actions with tubular magazines. Consult your rifle's manual and work up loads carefully to ensure safety and accuracy with your specific firearm.

How do I find the best seating depth for my load?

Barnes recommends experimenting between 0.03 and 0.07 inches off the lands (or per your reloading manual) to find where your rifle shoots most accurately. Start conservative, fire test groups, and adjust incrementally. The variation between rifles can be significant, so invest the time to develop a load tailored to your gun.

Will TSX bullets perform on large game like elk and moose?

Yes. The 250-grain weight and proven expansion design make these bullets suitable for heavy game. The flat-nose profile and 100 percent weight retention support deep penetration, though as always, shot placement remains paramount for ethical, effective hunting.
