I am willing to trade either one full spam can of Russian surplus 5.45x39 (7n6), or a sealed 100rd can of linked 50 BMG (Lake city, with tracers), for roughly 1200 rounds of 7.62x25 (equivalent to one Polish or Romanian spam can). Whether it is a a single sealed tin or a hodgepodge of different makers/vintages dumped unceremoniously into a box, I'd be happy. If there is something else you are looking for, go ahead and send me a PM; maybe I have it.
