Lake City Steel Cased M193 – Economy Ammo for the US Army in 1967
During the height of the Vietnam War, the famed US Lake City Army Ammunition Plant made steel-cased 5.56mm M193 ammunition for the US Army, as part of an effort to conserve valuable copper. This ammunition did not make it past the testing phase, as the project was abandoned in 1970, but it remains an interesting might-have-been today.
