description A percussion primer composition that comprises an explosive and a sensitizer, the explosive being a moderately insensitive explosive having an impact sensitivity in the range from about 0.3 kp m to about 0.75 kp m. The moderately insensitive explosive may comprise CL-20, PETN, RDX, HMX, or mixtures thereof. The sensitizer may comprise aluminum, titanium, zirconium, magnesium, melamine, styrene, lithium aluminum hydride, or mixtures thereof. In some instances, the percussion primer composition may comprise the moderately insensitive explosive precipitated onto the sensitizer. The percussion primer composition may contain an oxidizer, which in certain situations comprises a conventional oxidizer or a bismuth compound. The bismuth compound is bismuth trioxide, bismuth subnitrate, bismuth tetroxide, bismuth sulfide, or mixtures thereof. A gun cartridge and other primer-containing ordnance assemblies employing the percussion primer composition are also disclosed. Methods of forming the sensitized explosive and the percussion primer are also disclosed.
