New Russian Rival to 6mm ARC?

[UncleBob]

Not much info about it out there. By the dimensions the closest round would be something like the 6-6,8SPC. There is slightly more taper with shallower shoulder angle for easier extraction, which makes sense for a military cartridge. Of course, with Russia being stuck in the middle of a shooting war, I doubt they would be keen on adopting a whole new firearm system.
