"Pete",

If my memory serves me well, The term calibre came from the French Artillery and was the number of times that the bore devided into the barrel length.

This, I believe, was used in setting the range of the weapon.

It is still so used in Naval Terms.(Perhaps in the Pressure ,time, and distance traveled.(Internal Ballistics)

Some where along the line it was mis-directed to mean a measure of bore diameter independent of the barrel length.

As I seem to recall.
