Jacketless hunting bullet with roll-back cutting flags

Image Number 2 for United States Patent #4044685.

A jacketless hunting projectile or bullet of the mushrooming-tip, high cutting-type has a projectile body including a solid cylindrical guide part and a hollow head tapering toward a point. The hollow head has a progressively increasing wall thickness toward the solid part of the bullet and defines a cylindrical hollow space which receives a filling of a spreading material forming the tip of the projectile. This material rolls back the head after splitting it along notches formed in the hollow wall with sharp edges.
