Alliant Pro 300-MP

Alliant Powder continues a long and proud tradition of producing America's best and most popular smokeless powders. Our Mission: Premium Performance, Consistent Quality Every container of Alliant smokeless powder is backed by a century of manufacturing experience and the most exacting quality control procedures in the industry. We check and control chemical composition, the shape and size of powder grains, and even the propellants' density and porosity. We send samples of every batch to our ballistics lab, testing for burning speed, among other things. Then, after blending batches together for exactly the right ballistic characteristics, we use our advanced computerized equipment to test again. The result: a line of products known and respected for consistent quality and performance — not only in the lab but especially on the firing line. After all, one of the reasons you're a reloader is so you'll know exactly what to expect every time you pull the trigger. With Alliant powders, you will. Not only shell after shell but also year after year.
