Abstract
The detonating bore in the rear wall of a shaped charge case is outwardly convex. A powdered explosive is compacted into the case through the open front opposite the detonating bore, causing the portion which enters the convex end of the bore from within the case to be less compacted and less dense, for increased sensitivity and more reliable detonation.
