I think they are getting edgy as well. My LGS has 5.56 ammo on shelf for .50 per round. 9mm has been hitting wal-marts shelves regularly. ARs are also sitting on the shelf now.. 750 for a dpms oracle.
I see ads in the newspaper now of ppl trying to dump 5.56 ammo for .50-60 cents a round. I even see overlapping ads where they are dropping their price. This tells me that people have enough ammo at this point and are unwilling to pay crazy prices.
In a month people will be lucky to get rid of primers for what they have into them.
