Winchester WSF Smokeless Powder 1 lb. Jug.
Super-Field propellant is the propellant of choice for Winchester 20 gauge AA Target Load and 12 gauge 3 3/4 dram equivalent Super-X load. WSF is an ideal choice to maximize velocities in 12 gauge 1 1/8 oz. and 1 1/4 oz. loads. Super-Field also performs well in 38 Super, 9mm and 40 S&W pistol loads. Excellent propellant for fast shooting action pistol applications.
