Abstract: A shotgun cartridge having a weighted wad for controlling the separation point between the wad and the shot load. The wad having a tail portion and a nose portion with the nose portion shifting the center of gravity of the wad axially forward away from the center of pressure compared to where the center of gravity would be if the nose portion was not weighted thereby controlling the shot load separation and enhancing the shot pattern.
