.46 rimfire / 11.6x21mmRF is a family of rimfire cartridges which were chambered in revolvers and rifles in the late 19th and early 20th centuries. They were primarily made in short, long and extra long lengths; however, a variety of other lengths were designed. Manufacturers in the USA discontinued making .46 Short and .46 Long ammunition after the country's entrance into World War I in 1917; however, production of .46 Extra Long / 11.6x39mmRF continued after the war.
