I agree that, to some extent, the 2008 panic never really ended. As far as some things like AR15s are concerned though, most who had an inkling to buy have already done it so I don't see a price spike likely.
For all of the new shooters who bought .22s and the old timers who stocked up, .22 and pistol powder is still a problem but, eventually, everyone's pantry will fill up and it will sit on the shelves even as the anti's do their thing
In some ways I have come to see the media's anti 2A stance as a good thing. Every time that the idea of gun control is brought up again, a hole new batch of gun owners is born out of the panic and us old timers stock up a little more.
