Your best bet will be at some gun shows thru private sellers not the tour de force guys that setup at every show in the western hemisphere. My Russian supplier was spanked by the state customs people so I don't expect to see my shipment anytime soon.
Patience and a little luck and you'll find some, I still do.
I'm glad I stocked up 8-9 years ago. I stopped buying them when they went north of $30, same with the ((10)) 5.56 black mags.
