Need help to ID some 7.62x25 ammo.

[MVP]

Recently I bought a crate of 2 spam can 7.62x25 Tok ammo from Marstar Canada.
After I received the crate I found there were thousands of dead ants in the crate but luckily the spam cans were intact. The ants built a colony in the crate!

The spam cans were painted green.

There are 2 numbers and 2 stars on the head stamp.
3 @ 12 o'clock location
46 @ 6 o'clock location
and 2 star @ 9 and 3 o'clock location.
The ammo have brass cases and the projectiles attract to a magnet, so possibility steel jacket or steel core?

Marstar said it is Russian surplus but I only saw copper washed steel case Russian 7.62x25 before, so I'd like have someone help me to ID this ammo. Also, does anyone know if these are steel core or not?

Thanks for helping me!!
