How is caliber defined?
Caliber typically refers to the maximum diameter of a gun's barrel in hundredths of an inch. Sometimes a stated caliber (like .38 Special) is not equal to its actual caliber (.357 caliber). This is due to several reasons: 1- Marketing, 2- Measuring barrel diameter land to land, 3- Measuring barrel diameter groove to groove. 4- Measuring diameter of the chamber (brass casing diameter). Usually when a firearm uses millimeter instead of caliber, it tends to be a more accurate description of the projectile's diameter.
