Caliber - Wikipedia, the free encyclopedia
I assume it's for brevity's sake. Who wants to say "point twenty two" if you can say "twenty two"?
In print, guns are described as .22, .38, .45 etc.
In speech, however, the decimal point is never mentioned.
What is the origin of this practice?
And why the 'point' before 'blank'. Imagine someone being shot with a point 22 at blank range?
