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.
