It's estimated that there are somewhere between 200 million ansd 300 million firearms in the US. If just 150 million are fired occasionally, and not in the attic somewhere gathering dust and cobwebs, and if everyone bought one (1) box of 50 rounds for each one since Newtown, that's -- ummmmm 7.5 billion rounds. Since December.
Well, at least someone else around here still uses their brain instead of flying into a panic at every hyped up alarmist story. Kudos to you, sir.
