The length of the barrel (especially for larger guns) is often quoted in multiples of the caliber, used, for example, in US naval rifles 3 in (76 mm) or larger. [2] The effective length of the barrel (from breech to muzzle) is divided by the barrel diameter to give a dimensionless quantity.
Most outdoor ranges restrict the maximum caliber size and/or projectile energy based on the design specification of the range. Some target-shooting ranges have separate facilities devoted to the use of higher-powered firearms such as .50 caliber.

While modern firearms are generally referred to by the name of the cartridge the gun is chambered for, they are still categorized together based on bore diameter. [citation needed] For example, a firearm might be described as a "30 caliber rifle", which could accommodate any of a wide range of cartridges using a roughly 0.30 inches (7.6 mm) projectile; or as a "22 rimfire", referring to any ...

Note that each category will include weapons that are in that general size class. Weapons of similar caliber may differ in exact caliber (i.e. 76 mm and 76.2 mm will both be under 76 mm artillery). Non metric calibers are placed within the nearest calculated metric category.
These included Navy guns Marks 2 through 6, of 30, 40, 45, and 50 calibers length. All of the Bannerman guns were 30 calibers long; the number of guns of other lengths is unclear. Sources state that all Navy guns were cut down to 30 calibers barrel length in an attempt to standardize ballistics, as that was the length of the shortest Navy guns.
