It's a huge panic across the United States. Obama's record on anti gun positions, he is the #1 gun sales person of the year. A month or so prior to the election when it looked like he was in the lead, sales started shooting up. The day after the election, shelves were cleaned off. According to one ammo manufacturer, there is about a 3-4 month back order time. So orders placed in November 08 are surfacing now. Prices have gone up some, but not significantly.
Some of the things about taxes and serial numbers were discussed, but I don't think those are the main fears. It is the unknown on what Obama will do. So instead of someone buying 1 box as they normally would do, then going to the store to get another box, they are buying up thousands of rounds. A panic is on with reloading supplies and everything else gun related.
The good news, if you call it that, with everything else going on with the economy, I think it would be hard to move some strict gun control on the agenda right now.
The recent announcement by Holder probably created another wave of panic. I noticed a few weeks ago, there was quite a bit of ammo that was being stocked up at retail stores vs. low inventories in November / December 2008. Holder wants to ban guns here because of problems in Mexico. They should just pass laws to make drugs illegal, then there would not be any problems.
