ABSTRACT:
A shock wave initiator device for initiating a percussion primer includes a primary explosive, an attenuation body, and a deflagrating member. The primary explosive is of a type which upon ignition is capable of detonation for producing a shock wave. The attenuation body is a block or core of material which at its exterior engages a cup of a primer enclosing primer mix and at its interior has a cavity housing the primary explosive. The body is capable of transmitting the shock wave produced by the detonation to the primer cup. The deflagrating member is preferably a rapid burn cord with one end communicating with the primary explosive and an opposite end communicating with a source of input energy for igniting the cord to cause burning thereof which, in turn, ignites and detonates the primary explosive.
