Winchester WC401 Super-X 40 S&W 165gr WinClean Brass 50rd Box

The Winchester WC401 Super-X 40 S&W ammunition delivers clean-burning performance with its innovative WinClean technology that significantly reduces lead fouling in barrels and actions. This 165-grain load combines consistent accuracy with reduced maintenance requirements for high-volume shooters. The brass enclosed base design prevents lead exposure during handling while maintaining reliable feeding in semi-automatic pistols.

What Makes This Different

Winchester's WinClean technology replaces traditional lead primers with clean-burning alternatives that reduce barrel fouling by up to 50% compared to standard ammunition. The enclosed base design fully encapsulates the lead core, eliminating lead residue on hands and reducing airborne particles during shooting. This ammunition maintains the same ballistic performance as traditional loads while offering measurably cleaner operation.
