The Barnes TSX Triple Shock Tipped TSX Bullets utilizes all-copper construction and innovative design, delivering reduced fouling, improved accuracy, greater velocity, and lower pressure for optimal control, as well as higher velocities, flatter trajectories, and less recoil. This construction also delivers nearly 100% weight retention and produces surer, deeper penetration with its specially engineered nose cavity that peels back into four sharp-edged petals that cut through game. This specially designed nose cavity expands to double the bullet's diameter almost immediately after impact at both high and low velocities, giving you a bullet that is as deadly on longer shots as it is at point-blank range.
