If you want to dismiss an entire article over that I guess it's up to you....Although, caliber just means diameter.
In firearms, the caliber is the diameter of the inside of the barrel. In a rifled barrel the distance is measured between the lands.
If the measurement is in inches then the caliber (abbreviated to cal) is quoted as decimal of an inch, so a (smallbore) rifle with a diameter of 0.22 inch is a .22 cal ("twenty-two caliber").
Calibers of weapons can be referred to in metric, as in a "caliber of eighty-eight millimetres" (88 mm) or "a hundred five-millimetre caliber gun" (sometimes abbreviated as '105 mm gun').
Small arms range in bore size from approximately .17 cal. up to .50 cal. Arms used to hunt big game may be as large as .80 caliber. In the middle of the 19th century, muskets and muzzle-loading rifles were .58 cal or larger.
