Good luck finding some ammunition online; SGammo.com Cabelas.com Natchezss.com Brownells.com Cheaperthandirt.com etc.
Many major brands; Ranger T, Speer Gold Dot, Hornady, DPX, etc are low or sold out(many with no back order).
It may be May or June until major sources come back up with ammunition supply pre-Sandy Hook, CT/event.
Panic & hysteria are all over the US now.
Every 2nd matters.
