Only downside of the 303 British is that it uses a .312" dia bullet rather than a .308" dia. First developed in 1888 as a black powder cartridge, it was adapted to smokeless powder in 1891 and remained Great Briton's standard rifle cartridge until the 1950s.

It's the reason that many of the Russian calibers are .311/.312" as they copied the 303 British cartridge and used it for many of their designs.
