The device is employed in connection with armor-piercing projectiles so as to improve penetration into armor. The projectile is in the form of a substantially rotation symmetrical projectile body containing a core and surrounding projectile body wherein the core is of a material which, under the penetration conditions prevailing for armor penetration, has a hardness which is greater than in the surrounding projectile body. In that a spiculated nose is formed, the mass forces on displacement of the armor material ahead of the projectile will be reduced and penentration will be increased.

An armour-piercing elongated arrow style projectile in the form of a substantially rotation symmetrical projectile body including a core centrally disposed and aligned in the longitudinal direction of the projectile, which comprises a core and surrounding projectile body wherein the core is of a material which, under the penetration conditions prevailing for armour penetration, has a hardness which is greater than twice the hardness of the material in the surrounding projectile body; that the entire length of the core is of a diameter which is between 5 and 25 percent of the largest diameter of the symmetrical projectile body and a length which is between 400 and 4000% of the largest diameter of the projectile body; and that the core is fixedly secured in the surrounding projectile body.
