During 1951 to 1953 the BBC (Britian/Belgium/Canada) Committee was formed in one last attempt to develop a new 7mm round acceptable to NATO. One of the cartridges they produced was the 7mm Compromise, also known as the T 65/7 mm. It was comprised of the US FAT1E3 case necked down to take a 7mm bullet. Versions of the cartridge were made in the three BBC countries as well as in the US.
