About Hercules Powder Company
The Hercules Powder Company, based in Wilmington, Delaware, was incorporated in 1912 after a U.S. court ordered the breakup of DuPont’s explosives and gunpowder business. It became one of the major American producers of smokeless powder, supplying the military in both World Wars and ranking 65th among U.S. corporations by the value of its World War II production contracts. On September 12, 1940, an explosion at its Kenvil, New Jersey, plant killed 51 people, according to contemporary reports.
For handloaders and shotgun shooters, Hercules is best remembered for canister powders such as Bullseye, Unique, Red Dot, Green Dot, Blue Dot and 2400, several of which date to the Laflin and Rand era and remain in production today under the Alliant Powder name. The company became Hercules, Inc. in 1966, sold its Hercules Aerospace business to Alliant Techsystems in 1995, and was merged into Ashland Inc. and dissolved in 2008. Many reloading manuals still list these powders by their Hercules-era names, a sign of the company’s lasting influence on American shooters.
