Every container of Alliant Smokeless Powder is backed by a century of manufacturing experience and the most exacting quality control procedures in the industry. Chemical composition, grain shape and size, and overall density are constantly checked and tested in a ballistics lab to ensure consistency.
Created as an "all-around" shotshell powder, Alliant's Unique powder is clean burning, versatile and can be used with most hulls, primers and shotshell wads. Unique is also a preferred powder for loading most popular handgun cartridges as well.
