Abstract (en)

[origin: WO03073034A1] The invention relates to a charge retaining mechanism (10) for retaining a charge (12) inside a chamber (14) of a barrel (16) of a gun, comprising retaining members consisting of a central retaining member (18.1) and two sets of end retaining members (18.2), extending from an elongate coil spring (20), into the chamber (14). The coil spring (20) is located in an elongate groove formation (22) cut into the inner surface of the barrel (16) and extending partially around the inner circumference of the barrel (16). The charge retaining members (18.1, 18.2) are movable between a charge passing position and a charge retaining position and are biased in the direction of the charge retaining position by means of the coil spring (20).
