A weapon round effective for multiple and structured targets, comprising: a propellant-containing casing and a subcaliber sagittate inertial impact projectile received in said casing and adapted to be fired through a barrel of a weapon, said subcaliber projectile comprising: an elongated projectile body; means on said body releasable therefrom and adapted to form a drive cage in said barrel; means forming a tip at a forward end of said body; and flight-path stabilizing means on a rear end of said body for directing said body toward a target, said body comprising: an armor-breaking stack of a multiplicity of partial cores each provided with a respective cutting edge turned toward said forward end, said cores all being composed of metal and having a cylindrical configuration, all of said cores being of equal diameter and having planar separating surfaces along which the respective cutting edges are formed, said cutting edges being sharp circular edges limiting glancing off upon inclined impact of said cores with the target; and means for centering said partial cores relative to one another and in successively abutting relationship, and for fixing said cores together to enable separation of said cores from said stack on impact of said projectile with said target whereby said cores successively pierce successively inwardly lying layers of the armor of said target, and for replacement of said cores in said stack, said means for centering and fixing said partial cores including a thin-walled soft casing surrounding said stack, and a cylindrical boss of each core received within a thin outer collar of an adjacent core, said collars carrying said cutting edges.
