Went to a Pawn shop I had never been in before, they had 3 - 4 kinds of 7.62x39 but none at quantity prices. They were:
Wolf HP - $4.00 a box, he had maybe 20 boxes
Unknown surplus Brass case packaged 15 rounds to a white box, no labels or markings on the boxes and priced at $3.50 per box. I'm not familiar with what these may have been, I remember a while back someone had some Yugo brass case that was in 15rd boxes, could have been but I really dont know.
Another odd looking surplus with crappy thin paper boxes a very light blue - green in color, 20 rounds to a box. No labling whatsoever. The cases were green lacquer but different looking than Wolf or most Russian I have seen, and had primers that had 6-8 crimps all the way around. And at $6.00 a box! Looked like he had maybe a couple thousand, but for that price you might as well go to MegaLo Mart and buy their white box.
