FIELD: weapons and ammunition.
SUBSTANCE: shaped charge with facing can be used in well perforation, incorporated with shaped perforators. Shaped charge comprises casing with axisymmetric grain that features open spherical-segment cavity and intermediate detonator fitted on the grain body face opposite the facing. Inert material facing adjoins the grain cavity surface. Aforesaid spherical-surface flanged-edge facing has its edge representing parts of torus with their radii sizes exceeding those of the facing to form the angle of at least 110 degrees and not over 180 degrees between opposite parts. Flanged edge lateral side is tightly pressed to casing inner side.
EFFECT: increased diametre of perforated hole.
