An explosive charge such as a cast booster charge (10, 110, 210) includes an explosive charge (14, 114, 214) having a first explosive matrix material (114a, 214a) with discrete bodies (118, 218) of a second material embedded therein. In some embodiments, discrete bodies may comprise explosive material and the first explosive matrix material (114a, 214a) may be more sensitive to initiation than the explosive material of the discrete bodies (118, 218). In a separate aspect of the invention, the discrete bodies may have a minimum dimension of at least 1 mil...
1. An explosive charge comprising: a continuous phase comprising a first explosive matrix material having therein a plurality of discrete bodies of a second material which is less sensitive to initiation than the continuous phase, the discrete bodies having a minimum dimension of at least 1 mm, where in the matrix material defines a contact surface for an initiator and wherein the discrete bodies are concentrated away from the contact surface to provide a region of high sensitivity near the contact surface. 2. The explosive charge of claim 1, wherei...
