Abstract

A charge holder assembly comprises: a charge holder, wherein the charge holder is a hollow cylinder, and wherein the charge holder comprises: (a) at least one hole disposed through a wall of the charge holder; and (b) at least one slot disposed through the wall of the charge holder, wherein the at least one slot is located diametrically opposite from the at least one hole; and a charge comprising a charge case, wherein the charge case comprises: (a) a tail end portion, wherein the tail end portion comprises: (i) a cord retaining groove; and (ii) two legs, wherein each of the two legs comprises at least one slot engaging groove, wherein the slot engaging grooves are at an angle offset from the cord retaining groove. A method of perforating a material comprises: positioning a perforation gun adjacent to the material; and causing the charge to detonate.
