The .270 British (or .270 Enfield) is an experimental intermediate rifle cartridge that was developed by the British at the same time as the .280 British as a potential successor to the .303 British cartridge.[1] The rimless cartridge has a base diameter of 11.3 mm (like the Russian 7.62×39mm) and a case length of 46 mm.[2] The bullet is a standard .270/.277 caliber bullet in a light 100 gr weight.

The cartridge was not adopted, the British initially focused development on the .280, then ultimately chose the NATO-standard 7.62x51 cartridge.
