The name, derived from an old English practice of bore measurements in gun-making which refers to a nominally 4-gauge bore, that is, a bore diameter that would accommodate a pure lead round ball weighing 1 ⁄ 4 of a pound. This would imply a bore diameter of 1.052-inch (26.7 mm), however in practice the bore diameter varied greatly as, in ...
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point. This is a table of selected pistol / submachine gun and rifle / machine gun cartridges by common name.

This is a list of firearm cartridges which have bullets in the 4 millimetres (0.16 in) to 4.99 millimetres (0.196 in) caliber range. All measurements are in mm (in).

It follows in a long line of illustrious big bore cartridges introduced by Holland & Holland, the last of which was the .700 Nitro Express.
