摘要： A projectile (14) for an ammunition round (10) for use with a small arms or light firearm comprises an elongated projectile body (16). The projectile body (16) has first and second axially opposed ends (18, 20) respectively and a cavity (20) extending there between. The cavity is able to hold a quantity of propellant (24). A plurality of seals (26) extend about an outer surface of the body (16). The seals (26) protrude radially from the body (16) and operate to form a substantial seal against an inner circumferential surface of a barrel (12) of the firearm. Two of the seals (26b and 26c) are mutually adjacent and spaced apart in a direction of a longitudinal axis of the body to form a seal bound outer surface portion (36) of the body (16). One or more holes (38) are formed in the body (16) enabling fluid communication between the cavity (22) and the seal bound outer surface portion (36) of the body (16). This enables pressure equalization inside and outside of the cavity (22) about the seal bound outer surface portion (36) when the projectile (14) is travelling through the barrel (12).
