Barnes Triple-Shock X (TSX) 7mm 140 Grain HPBT Lead-Free Bullets - Box of 50
Barnes Bullets
Barnes Triple-Shock X (TSX) 8mm 180 grain HPBT lead-free bullets are built for reloaders pursuing medium to large game where shot placement and terminal performance matter. Constructed entirely from solid copper, these bullets deliver the kind of reliable expansion and penetration that separate one-shot kills from wounded animals heading for the next county. Whether you're handloading for an 8mm Mauser, an 8x57 IS, or another 8mm rifle cartridge, TSX bullets have earned a reputation among precision hunters who won't compromise on consistency.
The TSX design hinges on controlled expansion that generates four razor-sharp cutting petals while the bullet core stays bound to the jacket through impact. That means near-total weight retention—critical when you're driving through heavy bone, muscle, and distance to reach vitals. Lead-free construction makes these rounds compliant in jurisdictions with non-toxic ammunition regulations, and they deliver the ballistic performance you'd expect from a premium copper bullet at hunting velocities.
For reloaders, seating depth significantly affects accuracy; Barnes recommends experimenting with jump distance between 0.03 and 0.07 inches from the lands, then working up loads in your specific rifle to find the sweet spot. Every rifle is different, and fine-tuning this variable often unlocks tighter groups. This box contains 50 bullets, enough for serious load development or a solid season's hunting preparation.

Barnes TSX 180-grain 8mm bullets are suitable for any 8mm rifle chambering that uses this bullet diameter and weight class—including 8x57 IS, 8mm Mauser, and similar cartridges. Always verify your rifle's specific requirements before loading, and work up loads safely in your individual firearm.
Yes. These TSX bullets are constructed entirely from solid copper with no lead core, making them compliant with lead-free ammunition mandates in California and other jurisdictions that restrict lead ammunition for hunting.
Barnes recommends a range of 0.03 to 0.07 inches from the lands, but the optimal distance is rifle-specific. Load development—starting conservatively and working upward—is essential to find what your rifle shoots best.
Near-complete weight retention means the bullet holds together through impact rather than fragmenting, delivering penetration deep enough to reach vitals on large game even through heavy bone and muscle. This reliability is why TSX bullets are favored by hunters who demand consistent one-shot performance.
