Abstract
One example apparatus includes a shaped charge, and an overmold that includes one or more layers surrounding a portion of the shaped charge. The overmold may contact, and conform to, a case within which the shaped charge is received, and the overmold may further contact, and conform to, a cartridge wall within which the shaped charge and the overmold are positioned. An electrical or electronic component may be partly embedded in the overmold.
