Almost looks like tulamo steel cased ammo. Nothing wrong with that though because you labled it as ak47 ammo which basically any ak can eat up but most other platform guns especially the "ar 15" platform hates steel cased ammo.
Ak47 ammo: 7.62x39
Ar15 ammo: 5.56x45
Ammo definitely varries based on gun and moddel within those platforms
Russia even made a caliber that's like if you combined those calibers: 5.45x39
There's a lot to this stuff, do some readin into gun stuff pretty fascinating.
