Abstract: A replaceable bullet cartridge that includes a primer and a cylindrical BB pellet positioned approximately ¼ th of an inch away from the primer. The BB pellet is secured in position with a piece of paper wadding set within the replaceable bullet cartridge which is fired from the replaceable bullet cartridge with the BB pellet when the primer is struck. There is no gun powder or propellant used in combination with the primer when using the replaceable bullet cartridge. The BB pellet and the piece of paper wadding are fired from the second end of the casing without a selected one of gun powder and expander propellant when the loaded primer is struck by a hammer. The resulting speeds of the BB pellet are in the range of 700 to 800 feet per second.
