A bullet comprises a casing (10) having a solid head (11) and a hollow space (14) open to the rear in which a pill-shaped explosive charge (13) closes the mouth of a firing and explosion chamber (12), the latter having blind bottom and being of frusto-conical shape. Percussion of the explosive charge (13) by the firing pin causes the air of the firing and explosion chamber (12) to be adiabatically compressed, thus effecting explosion of the explosive charge (13) and firing of the bullet.
