Yep. The metric designation for .303 British is 7.7x56R.

Interesting tidbit: .303 was one of the 3 different 7.7mm cartridges that the Japanese used during WWII. They used a rimmed, semi-rimmed, and a rimless cartridge in 7.7mm. Not interchangeable at all and a fine example of the complete lack of rational planning and supply problems they had.
