Advanced muzzle loader ammunition

A method of manufacturing a muzzle loaded ammunition round comprising a bullet and a consumable cartridge case, the method comprising:

• providing a fixed round comprising a bullet and a consumable cartridge case;
• the cartridge case is filled with at least one propellant composition, the cartridge case is constructed from a consumable material;
• the bullet is commonly engaged to the propellant composition at least via the cartridge case, the propellant composition has a charge weight, wherein the consumable material is a foamed celluloid;
• heating at least one sheet of a foamed celluloid to a predetermined softening temperature;
• stretching the at least one sheet about a cylindrical mandrel of a desired diameter of the consumable cartridge case;
• using a vacuum to pull the sheet into a desired shape of the consumable cartridge case;
• closing a first end of the consumable cartridge case;
• filling the consumable cartridge case with at least one propellant composition;
• and
• closing the second end of the consumable cartridge case.
