Task: Question Answering
Input (English): passage: Though .38 and .357 would seem to be different diameter chamberings, they are in fact identical, as 0.357 inches (9.07 mm) is the bullet diameter of the .38 Special cartridge. The .38 Special nomenclature relates to the previous use of heeled bullets (such as the .38 Short Colt), which were the same diameter as the case. The only external dimensional difference between .38 special and .357 magnum is the difference in case length; this was done to prevent accidentally loading a .357 magnum cartridge in to a .38 special revolver which isn't designed for the .357 magnum's higher chamber pressure. Case volume was not a factor in the increase in case length as the .38 Special cartridge was originally a black powder cartridge, and the .357 magnum was developed using only much denser smokeless powder.
 question: is a 38 special bigger than a 357?
Output (English): No
