Abstract
A primer for an explosive charge which is to be initiated by a fuse cord is sensitized by a loose charge of a high explosive, this high explosive being contained in a rigid, impermeable container which is so shaped that it at least partially surrounds the fuse cord. The container is of plastics or metal and preferably comprises at least one elongated concave surface which mates with and is supported by at least one metal rod which protrudes from the base of a mould in which the primer will be cast and which establishes a channel for a fusecord. The primers of this invention have more sensitivity and robustness than known primers, and require fusecords of lower charge weight.
