Winchester WinClean handgun ammunition provides a safer indoor range shooting environment by eliminating airborne lead exposure at the firing point. By incorporating a patented lead and heavy metal free primer with a unique brass enclosed base bullet design, WinClean prevents lead vaporization from the bullet's base. The result is a benchmark for cleanliness with less smoke, less barrel residue and remarkably cleaner guns and shell casings - all at a value price. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
