Explosive bulk charge

A method for providing an explosive bulk charge, comprising:

• providing a first contact surface configured to be selectively disposed substantially adjacent to a structure or material;
• providing a second end surface configured to selectively receive a detonator;
• and
• providing a curvilinear side surface joining the first contact surface and the second end surface;
• wherein the first contact surface, the second end surface, and the curvilinear side surface form a solid bi-truncated hemispherical structure formed from an explosive material.
