Shotgun & Pistol Powders

Hi-Skor 700-X - This extruded flake powder is ideally suited for shotshells in 12 and 16 gauge where clay target and light field loads are the norm. It doubles as an excellent pistol target powder for such cartridges as the .38 Special and .45 ACP and many more. 14 oz. container.
