Spherical vs extruded powder
Did you know?
WebExtruded powders do not meter as well through powder measures as do the denser spherical powders but frequently are cleaner-burning and often noted for their contributions to accuracy. My first selection in this category is IMR-4064, first introduced by DuPont in 1935 to replace the discontinued IMR-15½. Ball propellant (trademarked as Ball Powder by Olin Corporation and marketed as spherical powder by Hodgdon Powder Company ) 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 b…
