FIELD: weapons and ammunition; machine building.
SUBSTANCE: invention relates to ammunition for small arms, primarily, to armor-piercing cores of bullets. Proposed method of forming comprises cutting, forming and withdrawing of dummy. Forming is performed in multiple stages to produce ogival or conical shape. Every time deformation is started on dummy section not deformed yet. During every subsequent stage, new punch is used to process head part with decreased angle of taper of forming chamber. In forming ogival shape, final forming is carried out. Dummy is withdrawn by resting ejector on dummy rear end face. After every forming, annealing is additionally performed.
EFFECT: higher output, lower labor input, improved mechanical properties.
