Surplus Ammo Identification? 7.62

[L3O 710]

I bought two crates of ammo last year and I dont remember where my ammunition originated from and was wondering if somebody would be able to ID them. I bought a crate of 7.62x25 and a crate of 7.62x39. The 7.62x25 has the numbers 21 and 69 written on the headstamp while the 7.62x39 has 61 and 70 written on it.

Go here and rummage around. Downside is the numerous factories using the same numbers. Usually the first number.

The 21 69 is Hungarian, and the 61 70 is Chinese.
