Abstract

A projectile, especially for hand firearms and automatic pistols, including a core member formed of a first material and provided with a blind bore extending in the forward direction into an outwardly inclined truncated cone surface indentation in the core member. A projectile insert member formed of a second material which is more difficult to deform than the first material, contacts the core member along the outwardly inclined truncated cone surface thereof and is provided with a lug portion extending into said blind bore of the core member for detachably joining said insert member and said core member. A jacket member encompasses the rear portion of said core member and extends forwardly at least up to a zone of the core member surrounding said blind bore. The jacket member has a front edge portion which terminates at a spacing from the forward edge portion of the core member so as to provide an unjacketed strip portion of the core member thereat.
