Abstract
An explosive charge such as a cast booster charge ( ) includes an explosive charge ( ) having a first explosive matrix material ( , ) with discrete bodies ( ) of a second material embedded therein. In some embodiments, discrete bodies may comprise explosive material and the first explosive matrix material ( , ) may be more sensitive to initiation than the explosive material of the discrete bodies ( ). In a separate aspect of the invention, the discrete bodies may have a minimum dimension of at least 1 millimeter or, optionally, 1.6 millimeter, regardless of the explosive properties of the material therein. In a particular embodiment, discrete bodies may be shaped as cylindrical pellets rounded at at least one end. The cast booster charge ( ) may be produced by melting the first explosive, disposing discrete bodies therein and cooling the molten material to solid form.
