Ammo Ban?

I've noticed a drop in imported ammo since the UN had their week long meeting in July of 2006, about all I see at gun shows is the steel case Russian stuff.

I've seen very little in 9mm, or .223 I use to buy quite a bit of South African, German, Spanish, you know the good old days when you could buy a case of 9mm for $90

So where there is smoke there is perhaps fire?
