1. Marksmanship training apparatus for a weapon having a barrel, a cartridge chamber to hold a cartridge in position for firing and a firing mechanism for causing the cartridge to fire, said marksmanship training apparatus comprising:

  • an electrically conductive cartridge casing structured for disposition in the cartridge chamber of said weapon, said electrically conductive cartridge casing having a first end and a second end;

    energy emitting means positioned to emit energy from said first end of said electrically conductive cartridge casing when activated, said energy being a pulse of energy with a rise time of less than 8 milliseconds;

    a power source positioned within said electrically conductive cartridge casing and connected to said energy emitting means;

    energy activation means positioned within said electrically conductive cartridge casing and electrically connected to complete an electrical circuit through said energy emitting means, said electrically conductive cartridge casing, said power source and said energy activation means when said energy activation means is activated to the on position by the firing mechanism of said weapon and thereby activate said energy emitting means; and

    a transfer mechanism mounted for axial movement within said electrically conductive cartridge casing and positioned between said energy activation means and said second end of said electrically conductive cartridge casing to transfer the energy imparted by said firing mechanism to said energy activation means to activate said energy activation means;

    said energy activation means comprises a snap action switch including a stationary terminal which is electrically connected to the power source and movable terminal which is positioned to be contacted by said transfer mechanism and moved to contact said stationary terminal to activate said energy activation means;

    said movable terminal comprises a disc which is rigidly supported around the periphery thereof and includes a cupped portion which protrudes from said periphery in the direction of said transfer mechanism.
