whats between a .303 and a .303 british? I bought a surplus rifle years ago and dont know if the british is just part of the enfield name or part of the name of the caliber.
 
You have your teminology twisted up a bit.

Caliber means the diameter of the bullet and has nothing to do with a specific cartridge. Alot of people say caliber when they actually mean cartridge-so they are using the wrong terms.

The cartridge is 303 British.

.303 is a caliber or diameter of bullet. Not a specific cartridge.

So if the barrel is marked 303 British then it means the cartridge is a 303 British. Which also happens to be a .303 caliber.

A better example would be: A 30-06 SpringField and a 308 Winchester are cartridges---NOT calibers. They both happen to be 30 caliber cartridges, but they are not the same shell. Tom.
 
There is a 303 Savage but if its a surplus its probrably a Lee Enfield rifle and the cartridge is .303 British so the British is part of the cartrige name like the 30/40 Krag.

A 303 British actually shoots a .311 caliber bullet. 303 is NOT the bullet diameter. The inner diameter of the bore, as Europeans measure, is .303. As we measure them, it would be a .311. However, names, and numbers in names do not always reflect the true caliber of the bullet in a given cartridge. For example, a 308 Win actually shoots a .308 bullet, but a 270 Win actually shoots a .277 bullet and is simply called a 270, if that makes sense......
 
What you said makes sense...However, the way cartridges are named, will never make sense.

Try explaining the .357 Sig., or how about a .221 Fireball to someone that doesn't know anything about cartridges.
