what is causing this? the shooting in CT? didn't happen last major shooting, not likely to happen now. Hunker down with what you own, if not you are gonna be into those guns and ammo purchased right now deeper than you need to be. Think $120 glock mag that was worth $12 when the ban collapsed. Don't believe the hype.
I think it's a combo of having a lame-duck Obama in office combined with the shooting and his 2nd speech that basically left plenty of clues that he is planning on sponsoring some legislation or passing an executive order and the general reaction of Cerberus/Dick's/Cabelas/Other retail stores pulling ARs or Bushmasters (I've heard rumors, but nothing solid to be honest).
Then CTD stopped selling firearms and hiked prices so that's what it took to poke the first scared wilder-beast and now there's a stampede.
I'm personally thankful for the gouge. Now I can finally take my mind off of buying guns/ammo and focus on this knife habbit
