Abstract
A non-toxic primer composition for center-fire cartridges which provides improved ballistic data and is void of metallic oxidizing compounds. It is comprised of a mixture of about 10-30% by weight of nitrocellulose and/or a double based propellant such as Hercules Fines, approximately 30-75% by weight of two percussion-sensitive compounds such as DDNP and tetracene, and approximately 10-30% by weight of calcium silicide. The mixture provides improved propellant ignition and non-toxic ignition products, and minimizes misfires in that it contains no hygroscopic compounds.
