This lead-free, 100% copper-constructed bullet provides extreme penetration every time. Typically, this premium hunting bullet retains 100% of its original weight even after smashing through dense tissue and heavy bone. The Triple - Shock® bullet design incorporates a series of precisely positioned rings cut into the bullet’s body. These grooves relieve firing pressure, allowing the TSX® to be safely loaded to higher velocities while reducing copper fouling. The bonus is that this is one of the most accurate hunting bullets you can buy.
