A PROJECTILE BODY AND CORRESPONDING AMMUNITION ROUND FOR SMALL ARMS OR A LIGHT FIREARM

摘要

- 20 Abstract A projectile 14 for an ammunition round 10 for use with a small arms or light firearm 5 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 body16. The seals 26 protrude radially from the body 16 and operate to form a substantial seal against an inner circumferential surface of a barrel 10 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 equalisation inside and outside of the cavity 22 15 about the seal bound outer surface portion 36 when the projectile 14 is travelling through the barrel 12. 47626602 (GHMatters) P93876.AU.1 15/10/13
