Chinese 7.62x54r Explosive bullet?


I pickup a sample of a Chinese 7.62x54R (321 code) dated 54.5 with a brass case and a nickel/silver bullet w/ a black and viloet or brown tipped bullet that was sold as a explosive bullet. I know that the Soviet WW.II explosive bullet was a red tipped but of copper construction. I look forward to any information on this cartridge.
