223 will still be around ,but with the stuff going on over in Georgia Wolf may become scarce.
I cant think of to many people who sell the 7.62x39 besides Wolf.
I hope it dosent get like 308 ,hard to find and expensive if you can find any.
I don't think the 7.62 stuff will get any mo scarce than what it is right now b/c of Georgia. Both sides predominantly use the 5.45 stuff with Georgia starting to use 5.56. It might get scarce for another reason.
