Time proven, dependability. Since 1922, Winchester Super-X ammunition has provided exceptional quality and outstanding performance. For decades, hunters and shooters have relied on Winchester Super-X handgun ammunition. Best known for time-proven dependability, the rounds offered include a hollow point and lead core for rapid expansion on game, as well as a thin-wall jacket, which reduces engraving forces for improved accuracy.
