The Tipped TSX (TTSX™ ) bullet features a polymer tip extending into a specially engineered nose cavity in the all-copper TSX body. The combination of tip and cavity initiates rapid expansion the instant the bullet strikes game. The streamlined tip also increases the ballistic coefficient of the TTSX bullets for superior long-range performance. This bullet expands reliably over a broad range of velocities. Some of these bullets will be available near the end of 2007, and will be offered in four different calibers beginning 2008.
