If ARcountryboy or anybody else still wants to know what my bulk Yugo 8mm rds. looks like (or some of them), the letters are written in Cyrillic.
One of the symbols looks like an upside down square U. Imagine the shape of a doorway with a normal opening at the bottom. These two 'doorways' are followed by a 'Y'.
On some of my Yugo ammo the date '1982' is at the bottom of the case head.
For those of you who will acquire surplus Czechoslovakian ammo, you probably know that their alphabet is not Cyrillic, but Roman like ours.
If it helps, I can give info on my Czech ammo.
