Need help to ID some 7.62x25 ammo.

Comparing this two cartridges.

For 38-77
The core of the projectile was very hard to scratch with a screw driver and attracted by a magnet so I assumed it is steel core.

For 3-46
Core was separated from the jacket when I cut it open with a angle grinder. The core was soft, easily scratched and marked and did not attracted by a magnet. The jacket did attracted by a magnet so I assumed it is copper washed lead core with steel jacket.

The steel core projectile (38-77) is longer than the lead core projectile (3-46). (Someone mentioned this in another forum)

The powder in (3-46) is more than the powder in (38-77), Maybe (3-46) runs hotter?

First three images are the cut opened projectile from (3-46). The 5th image is the cross section of (38-77)

MVP, I collect all variations of 7.62 Tokarev cartridges and boxes. I have both the rounds, but I could use those boxes......one for an addition and the other for an upgrade. Please PM me if you can mail the empty boxes to me here in The Great Green South. If course I'll pay any costs.
