This is 243 Win Norma American Professional Hunter Ammo in 100gr. Oryx Soft Point. The Oryx has a thin forward jacket with internal splitting zones to ensure perfect mushrooming at all impact velocities. The bonding, as well as the thicker rear jacket wall, ensure a high residual weight after impact (often exceeding 90%!) and excellent penetration. Oryx leaves a large wound channel while destroying little meat due to its rapid expansion to a large diameter and lack of fragmentation. Furthermore, the bullet's high residual weight ensures deep penetration and high energy transfer.
