Overview of .303 British Ammo
.303 British is the rimmed rifle cartridge of the British Empire, best known in the Lee-Enfield rifles carried through both World Wars. It fires a .311 to .312-inch bullet, usually 150 to 180 grains, at around 2,400 to 2,700 fps. That puts it close to .308 Winchester in power, making it a capable deer, black bear, and elk cartridge as well as a favorite of military rifle collectors.
Many surplus Lee-Enfield rifles are still in use, and modern factory ammunition is loaded with boxer-primed, reloadable brass. For another classic military rifle cartridge, see our 7.62x54R ammo.

Frequently Asked Questions
Is .303 British good for deer hunting?
Yes. With a 150 to 180-grain soft point, .303 British has similar power to .308 Winchester and is effective on deer out to about 300 yards. Many hunters still take deer and elk every year with Lee-Enfield rifles. Check your state's hunting regulations.
Is .303 British the same as 7.62x54R or .308?
No. .303 British is a rimmed cartridge with its own case dimensions. It is not interchangeable with 7.62x54R, .308 Winchester, or any other cartridge, even though bullet diameters are similar.
Is modern .303 British ammo safe in old Lee-Enfield rifles?
Modern factory .303 British is loaded to standard pressures intended for these rifles, but any surplus military rifle should be inspected by a qualified gunsmith before firing, especially for headspace.
More About .303 British Ammo
Britain adopted .303 British in 1888, first with black powder and soon after with smokeless cordite. It served as the standard British and Commonwealth rifle and machine gun cartridge for more than 60 years, in the Lee-Metford, Lee-Enfield, Vickers machine gun, and Bren gun.
After the British Army adopted 7.62x51mm NATO in the 1950s, millions of surplus Lee-Enfield rifles reached civilian shooters around the world. Today .303 British remains popular with collectors, vintage military match shooters, and hunters in Canada, Australia, and the United States.
