The cartridge was later designated 7 mm MK1Z, and has also been known as .280/30, .280 Enfield, 7 mm FN Short and 7×43mm. Like most armed forces in the immediate post-World War II era, the British Army began experimenting with lighter rounds after meeting the German StG 44 with the 7.92 Kurz round in combat. The Army began development in the late 1940s with the .280 and it was approved for testing in 1947. In 1949 the rim diameter was increased to .473 inch (12 mm), the same as the United States' standard Caliber .30 ammunition, and redesignated .280/30, the bullet was changed to a heavier 139 gr (9.0 g), with a mild steel core still at 2270 fps.
