Abstract
A lighter and faster bullet with a copper jacket and an aluminum core which is formed by first folding or rolling sheets of a thin metal such as aluminum foil into a cylinder and then inserting the cylinder into the jacket. The cylinder is then compressed within the bullet jacket without damaging the jacket by means of a bullet press. To increase the weight of the projectile, lead or other metals of different specific gravities are added to the jacket prior to insertion of the cylinder and compression.
