In the 2008 panic ammo and guns were starting to come back around this area by mid April.
It seemed to coincide with income taxes coming due. I'm predicting much the same this time.
That said, the panic was larger in scale in 2012 than it was in 2008. It's taking manufacturers longer to catch up with the backlog, and I'd expect ammunition to be tricky through August.
From December until recently, it was a seller's market on many things. In a month or so, that will flip, and we'll be seeing fire-sale pricing for "unfired LNIB" AR-15 rifles all over the secondary market.
