[1] Manufacturers in the USA generally discontinued making .32 rimfire ammunition after the country's entrance into World War II in 1941.

[1] Occasionally, special limited runs of .32 rimfire ammunition are manufactured for gun collectors with shootable specimens, but the round is not considered a current commercial cartridge.

[3] The .32 Short fired an 80 gr (0.183 oz; 5.184 g) lead bullet at 945 ft/s (288 m/s) (generating 159 ft⋅lb (216 J) muzzle energy) from a 24 in (61 cm) rifle barrel.

The .32 Long fired a slightly heavier 90 gr (0.206 oz; 5.832 g) bullet at approximately the same velocity, for 178 ft⋅lb (241 J) muzzle energy.

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.
