ABSTRACT:
A wad for a shotgun shotshell with a crimped case, comprising a seal member located adjacent to a propellant in the case and a rotor opposed to the seal member. The seal member and the rotor are interconnected for relative sliding and rotation and have opposed end faces. The seal member has at least one explosion gas passage hole. The rotor has, on the end face opposed to the seal member, gas jet grooves which are spaced from the axis and which extend in a predetermined direction to be connected to the outer periphery of the rotor and to the hole of the seal member. The rotor has blades or male-female connectors for transmitting the rotation of the rotor to a projectile in the case.
