These bullets also hold together better because the Hot Cor process eliminates the lead oxide layer that's found between the core and jacket of conventional "cold core" bullets. This translates into a bullet that offers deeper penetration and greater expansion that is needed for taking larger game. This is not loaded ammunition. Technical Information
