S&W and S&W-Fiocchi brand made mid-70's through early 80's. Made by several manufacturers including Winchester, Federal, AMRON, and with components made by others including Norma and Starline. It is collectors ammo. Several years ago, before I started collecting, two-thirds of the S&W-F 9mm I dropped the hammer on wouldn't go off. Sell it to a collector (like me) and buy reliable recent production ammo for shooting. Headstamps can be S&W, S&W-F, AMRON, even blank except for caliber; but lots of manufacturers produced ammo and components for the S&W and S&W-Fiocchi brands.
