The Barnes TSX Bullets in .22 caliber, 55 grains, flat base (Barnes part no. 30182), are an all-copper Triple-Shock X bullet for handloaders who want deep, controlled penetration without the fragmentation risk of a lead-core bullet. With no lead core to separate from the jacket, the bullet holds together through bone and tissue instead of shedding weight on impact.

Key Specifications

• .22 caliber, .224-inch diameter bullet is sized for .22-caliber rifle cartridges.
• 55-grain weight is a varmint-to-predator weight for the .22 caliber platform.
• 50 bullets per box gives enough for load development plus a season of shooting.
• All-copper monolithic construction eliminates the lead core, so the bullet cannot fragment or shed weight.
• Flat base design (rather than boat tail) is built for this specific loading.
• 28% deeper penetration than lead-core bullets comes from the bullet holding together instead of shedding mass.
• Precisely engineered rings cut into the bullet shank act as relief valves, reducing pressure for higher-velocity loads and cutting copper fouling.
• Four-petal expansion with deep cutting is designed for a clean, effective kill.
• Near-100% weight retention delivers nearly the full bullet weight on impact.

Frequently Asked Questions

Why choose an all-copper bullet over lead-core? An all-copper TSX bullet cannot fragment or separate from its jacket, so it penetrates deeper and retains more weight than a comparable lead-core bullet.

What is the ideal bullet seating depth? Barnes recommends seating from 0.03 to 0.07 inches, adjusted based on the specific rifle.

Is this a boat tail or flat base bullet? This is a flat base (FB) bullet, not a boat tail design.
