Abstract

A user-fillable shaped charge (110) comprises: a main container (115) for receiving main explosive material (125) and a projectile (120); and an auxiliary container (130) for receiving auxiliary explosive material (145) and an initiator (135). The auxiliary container (130) is connectable to the main container (115) to allow initial detonation in the auxiliary explosive material (145) to propagate to the main explosive material (125) and cause formation of the projectile (120). The charge (110) comprises a wave shaper (160) for controlling the initial detonation propagation across the interface (155) between the auxiliary explosive material (145) and the main explosive material (125), to improve the efficiency and/or accuracy of projectile formation in use.
