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. With a similar burn speed to IMR’s 4350 powder, Reloder 17 was designed for short magnum cases but can also be used in medium rifle loads. With Alliant Reloder 17 reloaders have a powder that meters easy and consistently while providing maximum velocity even in extreme weather. This consistent performance is what reloaders have come to expect from Alliant Powder – and Reloder 17 proves worthy.
