History
Developed by TsNIITochMash in the 1980s for Spetsnaz special forces. The VSS Vintorez ('thread-cutting saw') and AS Val were purpose-built rifles for this cartridge. All are integrally suppressed. Standard military loads remain subsonic, making the combination essentially hearing-safe and extremely difficult to locate by sound.
