Projectile, especially for hand firearms and automatic pistols
First Claim
1. A projectile for hand firearms and automatic pistols comprising a projectile core member formed of a first material and provided with a blind bore extending in the forward direction of the projectile into an outwardly inclined truncated cone surface indentation in said core member, a projectile insert member formed of a second material which is more difficult to deform than said first material, said insert member including a portion contacting said core member along the outwardly inclined truncated cone surface thereof and a lug portion extending from said contacting portion toward the rear of said core member into said blind bore of said core member for detachably joining said insert member and said core member, a jacket member encompassing the rear portion of said core member and extending forwardly at least up to a zone of said core member surrounding said blind bore, said jacket member having a front edge portion terminating at a spacing from the forward edge portion of said core member so as to provide an unjacketed strip portion of said core member thereat, said jacket member having the front edge portion thereof extending forwardly into a zone of said core member surrounding said truncated zone surface indentation, said core member being formed of a lead-weighted plastically deformable synthetic resin, and said insert member being formed of an impact-resistant plastic.

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.
