During the peak of the gun and ammo scare I sold a few of my Russian SKS originals. The bids far exceeded my wildest expectations for that rifle. But, this M67 ammo was selling above the clouds. A couple of guys got $2000 plus for one case of 1260 rounds.
My buyer of one had plenty of money to burn. He missed a case at $2200. He asked if I may have any M67 as he heard it was real Military brass cased ammo. Told him I had a few crates full. Then he told me about the auction he had lost. Offered me $2300 for a case. I sold it to him for that. What the heck? I got called a hoarder by several over that. But, the stuff is not available now either. The stuff is worth what a very knowledgeable buyer may offer for it. But it is the real thing with that M67 bullet that was designed to tumble like or better than the Russian 5.45. Plenty of info available about the horrific wounds it caused in those Balkan Wars.
Even today, I have no plans on selling any crate of it. But I can say positively right now I could easily get $750 and up from collector and some of my SHTF friends I know across the country.
So, it is not only good ammo, but the best X39 made ever I and others think.
