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.

A pistol bullet comprising an outer jacket of copper based material, said jacket including a solid base portion and a nose portion, said nose portion having a cylindrical wall that decreases in thickness away from the base portion and curves inwardly to form a cavity, said Wall having an inner surface, an outer surface, and an upper end, and a body of lead in the cavity that is bonded to the inner surface of the Wall of the cavity, said cylindrical wall having an outer lip of uniform thickness, with the wall at the lip of the cavity having a thickness between 0.012 and 0.015 inches and the ratio of the thickness of the lip to the thickness of the wall at the base being between 0.33-0.40 and the thickness of the base being about two times the thickness of the cavity wall at the base to provide a pistol bullet that will withstand high chamber pressures without deformation.
