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. Alliant Powder's 410 is a flake powder specifically designed for the exacting needs of .410 skeet and field loads. Being the cleanest burning .410 powder available, 410 is more efficient, with lower powder charge weights, providing optimum loading characteristics. The superior ballistic performance of 410 creates perfect patterns. Consistent performance in any weather, shot after shot, lot after lot, makes 410 your reloading powder of choice. Warnings from the Manufacturer:
- Do not exceed the loads displayed in the reloaders guide.
- Never mix any two powders regardless of type, brand, or source.
- Never substitute any smokeless powder for Black Powder or any Black Powder substitute.
