KDNP Drop-In Lead Styphnate Replacement for Ammunition and Cartridge Actuated Devices/Propellant Actuated Devices (CAD/PAD)

A military-grade drop-in replacement for lead styphnate in ammunition and other percussion primer applications

Military Technology

ImageCurrent percussion primers in small and medium caliber ammunition predominately use lead styphnate based formulations that pose a long term hazard to the environment, primer manufacturers, and the operator of the weapon since airborne vaporized lead results from each successfully fired cartridge. Nearly 12 tons of lead is consumed each year by the US military for small caliber ammunition alone. The vast majority of primer use by US military and domestic police forces (95%) is for training purposes, resulting in unsafe conditions at training ranges due lead and other heavy metal residues. As a result, the EPA and the FBI have designed lead as a primer ingredient that needs to be replaced and the DoD is under an Executive Order to reduce or eliminate hazardous substances wherever feasible.

The Naval Surface Warefare Center Indian Head Division (NSWC-IH) has demonstrate KDNP as a drop-in replacement for lead styphnate in the primers used in ammunition and cartridge actuated devices. The Al/Bi2O3 MIC composition provides comparable or superior performance to current military lead styphnate formulations such as FA-956 (No. 41 primer for all 5.56mm, 7.62mm and .50 cal ammunition) and 5086 (PVU-1/A primer for CAD/PAD applications).
