A projectile (610) for firing out of a firearm weapon comprises a substantially cylindrical projectile body (612) with first and second axially opposite ends (614, 616) and a cavity (618) defined between the first end (614) and the second end (616), for holding a quantity of propellant (622). The cylindrical body (612) has a first outer diameter, the first end being closed and the second end being open. The projectile further comprises at least two seals (630) extending about an outer circumferential surface (632) of the body (612). Each seal (630) protrudes radially from the body (612) to form a substantial seal against an inner circumferential surface of a barrel of a firearm weapon when the projectile is fired. Each seal (630) has a second outer diameter greater than the first outer diameter and equal to or greater than the inner diameter of the barrel. The projectile (610) has a case (668) in which the projectile is received. The case (668) comprises a tube (670) sealed at one end by a base (626)and open at an opposite end. The case (668) is fitted over a portion of the cylindrical body (612) with the base (626) adjacent the second end (616) of the cylindrical body (612) and closes the cavity (618) wherein said quantity of propellant (622) is retained within the cavity (618) by the base (626), and wherein the first end (614) of the cylindrical body protrudes from the open end of the case (668). |
