The 7.62 × 17 mm is a conventional rimless design resembling the 7.65 mm Browning although the Chinese round is a true rimless cartridge rather than semi-rimmed. The two rounds are therefore not interchangeable. The case is brass, straight tapered and Berdan primed. The Type 64 cartridge and the standard 7.62 × 17 mm cartridges fire a full metal jacket bullet. The Type 84 fires a semi-jacketed bullet with a protruding core that is said to be incapable of penetrating the passenger compartment of an aircraft at a
range of 2 m, but is capable of killing a human from 15 m. The cupro-nickel jacket of the Type 84 has striations at the juncture of the truncated cone penetrator to optimise expansion and tissue destruction. This cartridge was developed in the 1960s for use in suppressed pistols and first became known in the West after weapons chambered for it were used in Vietnam. It was originally described as 7.65 mm calibre, but NORINCO now describes it as 7.62 × 17 mm. A recent development in this calibre is the Type 84 cartridge for use in the NORINCO Mini Pistol of the same designation. Applications include 7.62 mm Mini-Pistol Type 84; 7.62 mm Pistol Type 80; 7.62 mm Silenced Pistol, Types 64 and 67; Type 77 pistol.
