Barnes' TTSX (Tipped Triple Shock X) features the same 100-percent copper body with multiple rings cut into the shank as the TSX, and delivers the same accuracy and dead-right-there performance, but with an added polymer tip that boosts BC and improves long-range ballistics. The tip and a re-engineered nose cavity provide even faster expansion. Complete penetration, virtually 100-percent weight retention, and four razor-sharp double-diameter cutting petals mean the TTSX creates more internal damage than any competing bullet. Instant expansion and perfect penetration ensure cleaner, quicker kills.Specifications: Brand: Barnes Bullets Caliber: 30 Cal Model: Tipped TSX Bullet Tip: Material Polymer Coefficient: .42 Core Material: Copper Solid Quantity: 50 Per Box Recommended Usage: Hunting Sectional Density: .226 Weight: 150 gr Bullet Diameter: .308 Bullet Type: TTSX Boat-Tail Cannelure: Yes Jacket Material: Copper Solid
