Olin Corp
A maker of chlorine, caustic soda, vinyls, and epoxy resins for coatings, wind energy, and electronics, Olin also owns Winchester, one of the largest U.S. ammunition brands. It began in 1892 when baseball-playing engineer Franklin Olin founded a blasting-powder company in Illinois that grew into Western Cartridge and merged with Mathieson Chemical in 1954. Its White Flyer brand supplies the clay targets used in skeet and trapshooting.
