Ball propellant (trademarked as Ball Powder by Olin Corporation and marketed as spherical powder by Hodgdon Powder Company[1]) is a form of nitrocellulose used in small arms cartridges. Ball propellant can be manufactured more rapidly with greater safety and less expense than extruded propellants.
Ball propellant was first used to load military small arms cartridges during World War II and has been manufactured for sale to handloading civilians since 1960.
