<p>A tracer wad for a cartridge comprises a shot holder consisting of four quadrants (34) defining between them a tubular member, a tracer element holder (127) and a conical recess (121) leading to a bore (126) for directing ignited propellant (14) onto a tracer element (27) held in the holder to ensure reliable ignition of the tracer element on firing of the cartridge (10). A flexible skirt portion (124) ensures a good gas seal between the wad and the barrel of a firearm when the cartridge is fired. When the wad leaves the barrel, the quadrants (34) are peeled back and the tracer element (27) leaves the holder to follow the trajeçtory of the shot (32).</p> |
