ABSTRACT:
A soft nose, bonded lead core bullet for rifles and pistols and a method of making the bullets is disclosed. The bullets have a Jacket of copper based material with a solid base portion and an upper nose portion having a cavity in which the lead core is located and bonded to the walls of the cavity. The walls of the cavity decrease in width away from the base and curves inwardly to form an ogive shape. The jacket increases in hardness and strength from the upper end of the cylindrical wall to the base of the bullet. The cylindrical wall has an outer lip between 0.012 and 0.020 inches wide and the ratio of the lip thickness to the bottom cavity wall thickness is about 0.18-0.20 for rifle bullets and about 0.3-0.4 for pistol bullets.
