Abstract
A wad-less shotshell ammunition cartridge may, if desired, have the hull inserted into a cup shaped metal head bottom portion. The hull is pressed into the cup shaped metal bottom portion. The primer is inserted into the center of cup. A measured amount of appropriate propellant is poured into the open end of hull. The measured amount of propellant. An amount of granulated obturating medium is poured into the open end of hull over the propellant. A selectively measured amount of spherically shaped projectiles are poured into the hull. A solid projectile is substituted for the spherically shaped projectiles. A packing tool presses the air out of the mixture of granulated obturating medium, spherically shaped projectiles and propellant. The air is pressed out of the mixture then the projectile is packed into the hull. The packing tool is removed and the open end of hull is reverse rolled and sealed.
