Every bottle of Alliant Herco Powder is guaranteed by a century of manufacturing experience and the industry’s most stringent quality control processes. To maintain uniformity, the chemical composition, grain shape and size, and overall density are continually verified and evaluated in a ballistics lab.

Herco smokeless powder has been used in shotshell loads since the 1920s and is an excellent high base hunting load appropriate for upland game and magnum handgun loads. Target loads of 10, 12, 16, 20, and 28 gauge can be employed.

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.
