.310 | 123gr | Barnes TAC-X
by Barnes
The Barnes TAC-X is a purpose-built tactical bullet featuring all-copper construction designed for military and law enforcement applications. Its unique four-petal design delivers controlled expansion while maintaining 100% weight retention through barriers including auto glass, plywood, drywall, and sheet metal. The grooved body reduces barrel fouling and pressure, while the boat-tail design enhances accuracy at extended ranges. TAC-X bullets are lead-free and California-compliant, making them suitable for training in environmentally sensitive areas. This bullet excels in .223/5.56mm, .308/7.62mm, and .300 Blackout platforms for both suppressed and standard configurations.
