Date Aug. 25, 1988.A penetrating projectile of a caliber less than or equal to 40 mm includes a core (1) provided with a front point (2). The core is made of a hard and/or high density metal or metallic alloy and has a portion (4) to the rear of the point that is surrounded by a ductile metal guide (3) having a substantially cylindrical wall. The portion of the core which is surrounded by the guide is provided with projections (5) and depressions (6), and the guide is crimped onto said portion of the core by electromagnetic forming such that the internal surface of the guide is fixed axially and rotationally to the portion (4) of the core (1) by means of the projections and depressions and the external surface of the guide reproduces the profile of the projections and depressions on the core. The projectile can be produced at low cost and has excellent ballistic properties. See FIG. 1. |
