    • An ammunition cartridge (1) has a casing (5) and a bullet (3). The casing (5) has a tubular body (23) closed at one end and attached at the other end to the bullet (3). An internal surface of the casing (5) attached to the bullet (3) is provided with a coating of copper oxide. The copper oxide may be black, for example black cupric oxide. The coating can result in a more consistent and reliable separation of the bullet (3) from the coated casing (5) compared to an uncoated casing (5) and this can assist the accuracy of the ammunition.
    • 弹药盒(1)具有壳体(5)和子弹(3)。 壳体(5)具有在一端封闭并且在另一端附接到子弹(3)的管状体(23)。 安装在子弹(3)上的壳体(5)的内表面设置有氧化铜涂层。 氧化铜可以是黑色的,例如黑色氧化铜。 与未涂覆的外壳(5)相比,涂层可以导致子弹(3)与涂覆的外壳(5)更一致和可靠的分离,并且这可以有助于弹药的准确性。
