Force amplifying initiating device |
摘要 |
A cartridge assembly 10 includes a shell 12 containing a propellant charge 19. At a rear, open end, the shell 12 holds a force amplifying initiating device 20, in turn holding a rim fire primer 22 in operative association with the propellant 19. A firing pin body 40 is movably held within the device 40 to expose a rear of the body 40 to a shock wave to initiate the device 20. A fore end of the body 40 includes a taper formation 48 having a rounded fore point 50 aligned with an inactive surface of the primer 22 centrally within a firing rim. Inadvertent (mechanical) actuation of the firing pin 40 will fall to cause sufficient and sufficiently fast impingement on the primer to initiate the primer. Only a shock wave can cause initiation. The primer 22 is held in a collar 34 allowing it to flare open upon initiation and holding it within the shell 12 after initiation.
