Winchester Super-X Power-Point ammunition is designed for exceptional performance and reliability, a tradition that began in 1922. It features a unique, exposed soft-nose jacketed bullet design that ensures maximum energy is delivered on target. The bullet's jacket is strategically notched around the mouth to improve upset performance and guarantee rapid, uniform expansion, which in turn leads to a massive energy release and quick, massive knock-down power on big game. The alloyed lead core helps to increase retained weight for deeper penetration. This time-proven ammunition is trusted by generations of hunters and shooters for its consistent and dependable performance.
