Provided is ammunition capable of increasing the movement velocity and shooting range of a bullet and enhancing the target hitting rate. The ammunition includes a case having a propellant chamber and a front mouth, a propellant charged into the propellant chamber of the case, a primer installed in the case for exploding the propellant when a physical or electrical impact is applied thereto, a bullet arranged in the front mouth of the case, the bullet having a streamlined tail portion for reduction of air resistance when the bullet is shot, and a wad fitted to the front mouth of the case for removably holding the bullet and closing the front mouth, the wad being separable from the bullet during explosion of the propellant.

1. 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); anda 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). 2. The ammunition as recited in claim 1, wherein the fixing means includes protrusions (62) formed in one of the bullet (50) and the bullet socket portion (44) of the wad (40) and grooves (64) formed in the other to engage with the protrusions (62), and wherein the protrusions (62) and the grooves (64) are disengaged from each other by an explosion impact of the propellant (20) to allow the bullet (50) to be separated from the wad (40). 3. The ammunition as recited in claim 2, wherein the protrusions (62) and the grooves (64) are inclined to extend in the same direction as the rifling of the barrel.
