These .999 fine copper bullets are replicas minted to have almost the exact dimensions of a real .45 ACP cartridge. Not for actual use in weapons, the splendid reproductions celebrate the cartridges John Browning designed in 1904 for his Colt semi-automatic .45 pistol. The 1 oz. copper content is inscribed on the bottom of each. These make an excellent gift for any outdoor or firearms enthusiast.
