Previously unknown to me and Russ Cornell, this brass cased 7.62x39mm from the People’s Republic of China recently turned up. The headstamp “71 61” has also been reported. This cartridge case can easily be mistaken for brass washed steel. In fact, Russ sent me pics of a “rubber bullet” dummy that he had listed for many years as BWS, when in fact it is brass! Are these as rare as we think? Who else has examples of this cartridge (or other headstamped BRASS cased Chinese 7.62x39mm)?
