British

The .303 British was the official military cartridge of England and the British Empire from 1888 until it was replaced by the 7.62 NATO in the 1950's. Originally a black powder cartridge, the .303 British was loaded with smokeless propellant after 1892. The original load for hunting used a 215 grain bullet and developed a good reputation for effectiveness on large game in the Canadian wilderness.

Of the same general performance and design of the U.S. .30-40 Krag, the .303 British is loaded to higher pressure levels making it better suited for handloading.

The SAAMI Maximum Average Pressure for the .303 British is 45,000 C.U.P.
