ABSTRACT:
The invention relates to a shotgun cartridge for shotgun shooting. The shotgun cartridge includes a case and a case head in it, in the vicinity of a primer arranged in which, a propelling charge is arranged. Inside the case is a shot wad with shot pellets arranged inside it, which are arranged on the opposite side of the propelling charge to the primer, and between the propelling charge and the shot pellets is a gas wad. In addition, the shotgun cartridge includes a indicator piece, arranged inside the shot wad, on the shot pellets side of the gas wad, in which there is a space for a indicator agent. The indicator piece is arranged to be ejected from the case when the shotgun cartridge is fired by igniting the propelling charge with the primer. The outer diameter of the indicator piece essentially corresponds to the inner diameter of the shot wad, and the indicator piece is arranged against the end wall of the shot wad with the shot pellets lying freely against the indicator piece. In addition, the indicator agent is a fine-particle incombustible substance, which is arranged loosely in the space.
