Need help on ammo indentity

[Tallship]

I picked a bunch of loose 7.62x54R ammo, and I'm curious what it consists of. the first picture is a brass cartridge with *321* on the top of the inner case bottom, and 53*7 on the bottom. The second is what looks to be a steel case with 21 on the top of the outer im and 73 on the bottom. The bullet looks to be smaller, too. The third on has 10 on te top and 80 on the bottom. O rmaybe it's 08 and 01? Also, the case is more copper colored.

Any ideas?

"321" is Chinese http://www.7.62x54r.net/MosinID/MosinAmmo026.htm

"21" is Hungarian http://www.7.62x54r.net/MosinID/MosinAmmo006.htm

"10" is Bulgarian http://www.7.62x54r.net/MosinID/MosinAmmo036.htm

The second one could be Hungarian, Polish, or East German, depending on the way the 21 is stamped and the color of the projectile. Your photo makes the projectile look black. If so, then it is an East German short range "practice" round.
