1. A method for fabricating a shaped charge, comprising:

  • (a) forming a hollow case having a rear wall and an open end opposite the rear wall,(b) forming a detonating bore in the rear wall of the hollow case,(c) forming an outwardly convex end in the detonating bore,(d) loading explosive powder material into the case substantially only through the open end thereof, and(e) compacting the explosive material within the case into a shaped charge, through the open end thereof and toward and against the rear wall thereof, to cause a portion of the explosive to enter the detonating bore and the convex end thereof and be less compacted and less dense in the convex end than in substantially the remainder of the explosive within the hollow case, for increased sensitivity and better and more reliable detonation of the shaped charge.
