I found some cases with the following headstamp:

At the 6 o'clock position there is: 02
At the 10 o'clock position there is: 7.62x39
At the 2 o'clock position there is: E.D.F.

Case is made from yellow brass, and apprears to have a boxer primer.

Any ideas who made this? I checked the sticky with the headstamp markings. Checked
the search feature on this site, checked Google...nothing.

Help appreciated.

Y-

Could it possibly be E.D.P?

If it is then it is Olympic ammo.  It is brass case and it is Boxer primed.

I have some and it is not so bad blasting ammo.  I haven't had any problems with it in 400 rounds or so.

The box says that it is non corrosive, but I treat all 7.62x39 ammo as corrosive and clean as if it is.

Roger that...
thanks!
