For heavy, hi-base shotshell loads for hunting, Alliant Bullseye Shotshell/Handgun Powder has been the trusted choice since 1920. The powder is made to deliver outstanding performance specific to heavy loads in 10, 12, 16, 20, and 28-gauge and .45 ACP target loads. All of Alliant powders are smokeless, made in the United States, and manufactured with strict quality control procedures. To ensure the best accuracy possible, the powder is checked for density, shape and size of the grain, and composition of the chemical.
