Xiahou is right - the calibre of a weapon or round is measured in millimetres (or inches or whatever unit of measurement).

Sometimes people use the shorthand of 'nine millimetre pistol' or '155 calibre gun' but it is only shorthand.

calibre

/kalibr/ (US caliber)

• noun 1 quality of character or level of ability. 2 the internal diameter of a gun barrel, or the diameter of a bullet or shell.

Yes, but when you see what are usually two mutually exclusive terms strung together it doesn't inspire confidence. Quite often confusing the two can lead to injury or death, i.e. firing a 10mm bullet from a .40 cal pistol, etc.

I don't wish to labour the point as we veer off topic, but the terms are not mutually exclusive - each is actually meaningless without the other - a calibre requires the descriptor of a measurement.

In your example, you are still using just the shorthand, which is confusing you. The correct meaning of your sentence is:

..firing a 10 millimetre calibre bullet from a .40 inch calibre pistol..

If you say 'a 10mm bullet' are you saying the bullet is 10mm long, square or what? By convention, most people would accept that you are actually saying it is 10 mm in diameter (calibre).

For brevity's sake, people leave out either the measurement or calibre word, but by doing so they have to know what is being left out. The original article was simply being accurate, using the full descriptor.

Make sense?

Be careful lads! If you keep this up, Kraxis will hijack the thread off into the Monastery and it won't stop until we've compared falconets, demi-culverins, 17-pounders, and the ballistic qualities of frozen European Swallows.
