Cannot find information about producer of BAIKAL 16X70 CARTRIDGES on photos. Are these cartridges were made in Krasnozavodsk cartridge plant? I saw BAIKAL marks also on cartridges from Bisk chemical plant too. Also possible version that BAIKAL is just marks for USSR cartridges and weapon which were made for export. Need professional opinion about possible producers and years of manufacture of these cartridges.
Thanks for help
