Claim 0:
1. A subassembly for an ammunition cartridge, the subassembly comprising:
a) a reusable case having a forward end and an aft end, the forward end being adapted to releasably attach to a bullet having a forward end and an aft end and a pressure chamber extending from its aft end and the case having an external wall extending from the case's aft end to the case's forward end, the case being adapted for use in at least one of a revolver and a rifle;
b) a primer cap; and
c) a reusable primer housing insert having a forward end and an aft end, the primer housing insert being adapted to releasably attach proximal to its aft end to an inside of the case's external wall proximal to the aft end of the case and having a first recess proximal to the primer housing insert's aft end adapted to releasably contain the primer cap and a channel communicating from the first recess to or through the primer housing insert's forward end;
wherein when the subassembly is combined with the bullet to form an ammunition cartridge, the forward end of the primer housing insert extends into the bullet's pressure chamber without connecting to the bullet and the primer housing insert is configured to expel a gas pressure pulse axially through its forward end into the bullet's pressure chamber.
