In a word; BANIC!
During last years feeding frenzy folks bought up everything will little thought about how practical it was and availability of ammo for it.
I'm sorry that I have been away for a while. Seems my employer wanted overtime and I wanted a paycheck.

I can't claim credit for the term "Banic" as I am sure others have used it but it is intended as a combination of the anti-gun policies of the Obama Administration and the lack of trust in the Government by many citizens.
Thank you for the kind words.
