ABSTRACT:
This specification discloses an ammunition round and a method of firing the ammunition round. Consecutive and reproducible firing of a primer charge and a main propellant charge is accomplished as a result of the physical movement of a divider physically separating the primer charge from the main charge. Firing of the primer charge causes movement of the divider, initiates movement of a projectile within the ammunition round, and, when the combustion gases of the primer charge are in communication with the main propellant charge, causes firing of the main propellant charge. The divider is retained within the ammunition round by a ring which limits movement of the divider.
