I've seen in a few places that there is allegedly an import "ban" on the corrosive 5.45 x 39 ammo in the spam cans... because they are "armor piercing" and somebody made a pistol that shoots this caliber. I've heard a recorded phone call on AK operators union 47-74 youtube page with the atf that said this is true... and Copes distributing says they can't get anymore... does anyone here have any additional info? I have multiple rifles that shoot this cartridge and I love the surplus prices for the spam cans... I would hate to lose this supply of cheap ammo.
