Sandy Hook was 556. Its not scarce. Cost maybe inflated but 22 is scare. I ain't buying that scenerio. Maybe its the most popular. There are lines at all the Big 5's every Tuesday to buy..22. Not 556 or 762. I do buy the hoarding reselling scenerio. But the state of Kali with all of its kommie gun laws would lend me to believe that there is a reason beyond Sandy Hook or Colorado theater. Even the gangsters in LA rarely use 22. I guess the common denominator is money. Even with inflated prices no one can keep 22 on the shelves. Not even Walmart.
