The term 'caliber' can refer to the actual diameter of the bore in inches or to a name given to a particular cartridge. The name may reflect the actual caliber, or not. In the case of .357 Magnum the name is the true measurement, while cartridges like .38 Special and .38/40 Winchester, also known as the .38 WCF both refer to .38 caliber while the caliber is actually .400" for .38/40 and .357" for .38 Special.What this means is that there are multiple guns that take different cartridges that can be described as ".357 caliber firearm".
