The .32 Short fired a 80 grain lead bullet at 945 feet per second from a 24-inch rifle barrel. The .32 Long fired a slightly heavier 90 grain bullet at approximately the same velocity. Remington rifles in .32 rimfire listed a bore diameter of .304 inch. During its lifetime, the .32 rimfire was loaded with black powder followed by semi-smokeless and smokeless powder loadings. While it was popular as a very effective small game caliber, it was considered obsolete by the late 1930s, in part due to the introduction of high velocity versions of the .22 Long Rifle using smokeless powder.
