  • Cartridge, Caliber 5.56 mm, Ball, M855 (United States): 5.56x45mm 62-grain FN SS109 ball cartridge, green tip w/steel penetrator and a lead core.
  • Cartridge, Caliber 5.56 mm, Ball, M855 Lead Free (United States):62-grain green tip w/tungsten penetrator and a steel core. Primarily used during training in countries with strict lead disposal laws.
When they talk about good-for-the-environment it's labeled "Lead Free." This is why you never shoot green tips at steel, ja?
