The Triple-Shock X-Bullet. Identifiable by rings cut into its copper body, it offers all the qualities that have made the X-Bullet a favorite of knowledgeable hunters everywhere. Like the X-Bullet, the Triple-Shock X features all-copper construction, no fragmentation, maximum weight retention and 28 percent deeper penetration than the best lead-core bullets offered. On impact, the bullet face opens to create four razor-sharp cutting edges. The Triple-Shock X ringed bullet provides significantly greater velocities, lower pressures and less fouling, without requiring an external coating. The bullet delivers a triple impact-one when it first strikes game, another as the bullet begins opening, and a third devastating impact when the specially engineered cavity fully expands to deliver extra shock with maximum transferred energy. Barnes' revolutionary Triple-Shock X design provides all the benefits of the time-proven XLC-coated X-Bullet. In addition to greater velocities, reduced pressures and less copper fouling, the Triple-Shock X delivers a three-punch impact that's deadly on game.
