Barnes Triple-Shock X (TSX) 338 Cal 225 Grain HPFB Lead-Free Bullets - Box of 50

Barnes Triple-Shock X (TSX) 338 caliber bullets in 225 grain are engineered for hunters and handloaders who demand terminal performance on big game. Built from 100 percent copper construction, these hollow-point, flat-base (HPFB) projectiles deliver controlled expansion and deep penetration through heavy bone and muscle—the kind of reliability that matters when a clean, ethical kill is the only option. Each box contains 50 rounds ready for your reloading bench or ammunition assembly.

The TSX design creates four razor-sharp petals upon impact, maximizing tissue damage and energy transfer while the solid copper construction ensures the bullet retains 100 percent of its original weight. This weight retention translates to superior penetration depth and consistent performance across a wide range of hunting distances and game sizes. Lead-free construction also makes these rounds a practical choice for hunters in sensitive ecosystems or regions with ammunition restrictions.

Handloaders will appreciate Barnes' precision engineering: optimal accuracy is typically achieved when seating these bullets 0.03 to 0.07 inches off the lands, though your specific rifle may require fine-tuning within that window. Whether you're loading for a bolt-action hunting rifle or a specialized large-caliber platform, the 225-grain weight in .338 offers the mass and sectional density serious long-range and dangerous-game hunters value.

Frequently Asked Questions

Are Barnes TSX bullets lead-free?

Yes. These bullets are manufactured from 100 percent copper and contain no lead, making them compliant with lead-ammunition restrictions in many regions and suitable for hunters concerned with environmental impact.

What kind of expansion can I expect from TSX bullets?

Barnes TSX bullets are designed to expand into four razor-sharp petals upon impact, creating a wide wound channel while retaining 100 percent of the bullet's original weight for deep penetration through bone and dense tissue.

How should I seat these bullets in my reloads?

Barnes recommends seating TSX bullets 0.03 to 0.07 inches off the lands for best accuracy, but the optimal distance may vary depending on your specific rifle and chamber. Start at the longer distance and work down incrementally to find your rifle's sweet spot.

Are these bullets suitable for hunting big game?

Yes. The 225-grain .338 TSX is designed for controlled expansion and deep penetration, making it well-suited for large-bodied game at extended ranges when loaded to appropriate velocities.
