Since the introduction of ORYX in 1996, we have been the industry benchmark in bonded bullets. With a combination of rapid expansion, high residual weight and deep penetration, ORYX is the number one all-round hunting bullet. When hitting the target, it expands quickly without fragmenting or breaking apart. Thanks to the unique bonding technology, ORYX offers residual weights up to 99% in some calibers on standard hunting ranges.
