Patent ID: 8485100

Claim:
An ammunition comprising: a case ( 10 ) having a propellant chamber ( 12 ) and a front mouth ( 14 ); a propellant ( 20 ) charged into the propellant chamber ( 12 ) of the case ( 10 ); a primer ( 30 ) installed in the case ( 10 ) for exploding the propellant ( 20 ) when a physical or electric al impact is applied thereto; a bullet ( 50 ) arranged in the front mouth ( 14 ) of the case ( 10 ), the bullet ( 50 ) having a streamlined tail portion ( 54 ) of conical shape with a pointed end for reduction of air resistance when the bullet ( 50 ) is shot, and the pointed end of the tail portion ( 54 ) being inserted into the propellant ( 20 ); and a wad ( 40 ) fitted to the front mouth ( 14 ) of the case ( 10 ) for removably holding the bullet ( 50 ) and closing the front mouth ( 14 ), the wad ( 40 ) being separable from the bullet ( 50 ) during explosion of the propellant ( 20 ), and wherein the wad ( 40 ) includes a body portion ( 42 ) removably fitted to the front mouth ( 14 ) of the case ( 10 ), a bullet socket portion ( 44 ) formed inside the body portion ( 42 ) so that the tail portion ( 54 ) of the bullet ( 50 ) can be fitted to the bullet socket portion ( 44 ) and a fixing means for removably fixing the tail portion ( 54 ) of the bullet ( 50 ) to the bullet socket portion ( 44 ), and wherein the bullet socket portion ( 44 ) of the wad ( 40 ) takes the form of truncated cone and has a through-hole ( 46 ) that allows the tail portion ( 54 ) of the bullet ( 50 ) to pass therethrough, and wherein the wad ( 40 ) has tooth-shaped protrusions ( 45 ) formed along a circumferential direction of the wad ( 40 ) so that the protrusions ( 45 ) can make frictional contact with a rifling of a barrel to increase the rotational force of the wad ( 40 ) and the bullet ( 50 ), and wherein the fixing means includes a paraffin adhesive ( 60 ) for bonding the tail portion ( 54 ) of the bullet ( 50 ) and the bullet socket portion ( 44 ) of the wad ( 40 ) together, the paraffin adhesive ( 60 ) being melted by the heat generated during explosion of the propellant ( 20 ) to allow the bullet ( 50 ) to be separated from the wad ( 40 ).
