The cylinder is bored straight through with no step. Later versions used an inside the case lubricated bullet of .357" diameter instead of the original .38" with a reduction in bore diameter. The difference in .38 Special bullet diameter and case diameter reflects the thickness of the case mouth (approximately 11/1000-inch per side).

This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
Automated Firearms Identification has its roots in the United States, the country with the highest per capita firearms ownership. [1] [2] In 1993, the Federal Bureau of Investigation commissioned Mnemonics Systems Inc. to develop Drugfire, which enabled law enforcement agencies to capture images of cartridge casings into computers, and automate the process of comparing a suspect cartridge ...
Caliber/calibre: In small arms, the internal diameter of a firearm's barrel or a cartridge's bullet, usually expressed in millimeters or hundredths of an inch; in measuring rifled barrels this may be measured across the lands (.303 British) or grooves (.308 Winchester) or; a specific cartridge for which a firearm is chambered, such as .45 ACP or .357 Magnum.
Lack of a case also reduces the weight of the cartridge substantially, especially in small bore rifles. For example, the external-propellant caseless ammunition designed by Austrian inventor Hubert Usel (1926–2010) for the Voere VEC-91 weighs about one third as much as regular ammunition for the same caliber.

The .308 x 1.5" case is available from a number of case manufacturers and differs from a homemade .308 x 1.5" in that it has a small primer pocket, whereas the original .308 Winchester case has a larger primer pocket (the smaller primer is more suited to the smaller case capacity of the short round).
