A completed cartridge with 5.8×42mm,developed by the factory 861
I understand this is a 6mm casless then?
Is a development year or the gun known?
To be honest it looks more like a 7.62mm.
The cartridges at the top are 7.62mm caseless cartridges,the cartridges at the bottom are 6mm cartridges.
Developed since 1971
Ok, this is a bit confusing.
Top is 7.62mm caseless and bottom is 6mm and not 5.8x42?
What is the 6mm case length?
Which years apply to the 7.62mm and which to the 6mm ?
They are not 5.8×42mm,the case length is unknown.
The caseless cartridge develooed from 1970,the 6mm cartridge developed from 1971.
And both are by factory #861?
Yes.They were both developed by the factory 861
