Abstract:
1. A muzzle loaded ammunition round in combination with a firearm, comprising: a fixed round comprising a bullet and a cartridge case; the cartridge case is hollow and is filled with at least one propellant composition, the cartridge case being constructed out of an energetic consumable material, and having a burn rate which can be selected by selecting the density of the consumable material of the cartridge case; the bullet is commonly engaged to the propellant composition at least via the cartridge case, the propellant composition having a charge weight; an igniter which extends into the propellant composition inside the case at the time of ignition; when the bullet is fired, an energy with which the bullet exits the firearm is a ratio proportional at least to the burn rate of the consumable cartridge case, the charge weight of the propellant composition, and at least one physical property of the bullet, the burn rate being proportional to the combustibility of both the propellant and the consumable cartridge case; the burn rate and the at least one physical property of the bullet are precisely calibrated to each other so as to yield ballistic properties in which the bullet is fired with a desired amount of kinetic energy and within the design constraints of the firearm.
