Barnes TSX Bullets .50 BMG .510" 647 gr BT 20/ct

The Barnes TSX Bullets .50 BMG .510" 647 grain Boat Tail ammunition delivers purpose-built performance for .50 caliber rifle applications requiring maximum penetration and controlled expansion. Engineered from 100 percent copper construction, these projectiles are designed to expand upon impact while retaining 100 percent of their original weight—a critical advantage when terminal performance and deep-bone penetration are non-negotiable.

Each round produces four razor-sharp cutting petals that create a wide wound channel through dense tissue and bone. The 647-grain mass and boat-tail design combine to support high-velocity ballistics while maintaining stability at extended range. The .510-inch diameter (.50 BMG specification) ensures proper chamber fit and consistent seating in precision reloading setups. Barnes TSX rounds are known for minimal fouling and consistent accuracy—essential for shooters demanding repeatability across multiple firing sequences.

Long-range rifle operators and precision shooters working with .50 BMG platforms rely on TSX ammunition for applications where one-shot reliability is paramount. This 20-count box provides a practical quantity for training, load development, or field use. The copper-alloy construction resists corrosion better than traditional lead-core projectiles, supporting longer storage life in challenging environments.

Barnes TSX ammunition has established a reputation among serious .50 BMG shooters and ballistic-testing professionals for consistent expansion data and weight retention—two metrics that directly influence predictable terminal ballistics and energy transfer downrange.
