Underwood 356 TSW 115gr Jacketed Hollow Point Ammunition, 20-Round Box

Underwood 356 TSW ammunition (model UW158) loads a 115-grain jacketed hollow point bullet for the 356 TSW, a rare cartridge developed for Team Smith & Wesson competition pistols. The JHP bullet is built with a traditional jacket-and-core design engineered to expand reliably on impact, unlike a full metal jacket target round. Underwood is one of the few manufacturers still loading this niche cartridge, keeping older competition and collector pistols chambered in 356 TSW fed. Each box holds 20 rounds of this hard-to-find load.
