I have a buddy who’s wanting some ammo that i no longer have a use for and has some Chinese 7.62x39 in yellow and green boxes. We figured out manufacturing plant and year from headstamps but can’t find any info on what it’s even worth. The info on the yellow boxes are also back and forth as to wether they may or may not be ap and I haven’t cut one up yet(they attract a magnet but it still may be a lead core) to find out. Any info would be appreciated,we already know the value of what i have that he wants and just want to do a fair trade with him.
