Barnes Triple-Shock X (TSX) 22 Caliber 78 Grain HPBT Lead-Free Bullets - Box of 50

The Barnes Triple-Shock X (TSX) 22 caliber bullets deliver proven all-copper performance for handloaders who demand reliability and terminal performance. Built from solid copper rather than lead-core construction, these 78-grain hollow-point boat-tail projectiles are engineered for consistent expansion and deep penetration—qualities that matter when hunting varmints, predators, or smaller game where shot placement and follow-through are critical. At 0.224 inches in diameter with a sectional density of 0.222, they're dimensioned for standard .22 centerfire rifle chambers and designed to deliver the weight retention and controlled expansion that serious reloaders expect.

What sets TSX bullets apart is their monolithic copper construction and the distinctive four-petal expansion geometry. Upon impact, the hollow-point cavity initiates controlled separation of the bullet jacket into razor-sharp cutting petals while the solid copper body typically retains 100% of its original weight—a combination that translates to deeper wound channels and more reliable performance through heavy bone and dense tissue than conventional jacketed or lead-core designs. Because they're all-copper with no lead, they're compliant where lead ammunition faces restrictions and appeal to hunters and shooters who prefer non-toxic projectiles.

Handloading with TSX requires attention to seating depth. Barnes recommends an initial starting point of 0.050 inches off the lands, but optimal accuracy typically falls somewhere between 0.030 and 0.070 depending on your specific rifle's chamber and throat. This is unloaded ammunition—you'll need brass, primers, powder, and the appropriate reloading equipment to assemble loaded cartridges. A box contains 50 bullets, giving you enough material for serious load development or a hunting season's worth of preparation.

Frequently Asked Questions

What rifles will these TSX bullets work in?

The 0.224-inch diameter and .22 caliber designation mean these are designed for standard .22 centerfire rifle chambers—such as .220 Swift, .22-250 Remington, .223 Remington, and other .22 centerfire cartridges. Always verify chamber and throat dimensions for your specific rifle before loading.

Do I need to seat these at a specific depth?

Barnes recommends starting at 0.050 inches off the lands. However, best accuracy is typically found somewhere between 0.030 and 0.070 inches depending on your individual rifle's chamber and throat geometry. You'll need to load test to find your gun's optimal seating depth.

Are these loaded ammunition or reloading components?

These are unloaded bullets only. You'll need to purchase brass cases, primers, and reloading powder, plus access to a reloading press and dies, to assemble complete ammunition.

Why choose all-copper bullets over conventional jacketed design?

All-copper TSX bullets typically retain 100% of their original weight through the target and create controlled, deep wound channels via four-petal expansion. They're also lead-free, making them compliant in areas where lead ammunition is restricted and appealing to hunters who prefer non-toxic projectiles.
