Shaper charge comprises right circular cone lateral covering that has, on its inner surface, multiple isolated recesses and elongated intersecting ledges, each with peculiar conditional line that passes along the ledge at equal distance from adjoining recesses. Aforesaid covering is made from sheet copper or copper-based alloy. Grid of conditional lines separates the covering surface into polygonal cells. Note that every cell has its smaller height length makes (5.0…7.5)h, where h is the covering thickness. Relief depth d, at the center of each cell, is selected from the condition d=(0.5…2.5)cos(α)h²/r, where α is half the angle of cone opening, r is the distance from the cell center to cone axis.
