A jacketed projectile having a preferably one-piece core, preferably of stee l, provides good performance regarding chamber pressure, barrel wear and accura cy by separating the jacket from a central tapered portion of the core to provide an encircling air gap that facilitates engraving of the jacket during firing. T he projectile is combined in a cartridge which is free of specific toxic substances, wheth er in the primer, propellant or other solid components.
