I remember back when it happened, there were lots of riots, power got cut off for days or weeks, because the power workers weren't getting paid, banks shut down. I think we ended up taking over their banks, and dollars were used for awhile to stabilise their economy. We are so big, no one will bail us out. Also, we have more diversity of races here, and riots could get ugly here. I work for a utility company and if I wasn't getting paid, I would go home to protect my family and stuff. Could come to that here. Anyways, back to the subject. That is why I choose military calibers as the primary defensive weapons, cheap, fmj ammo. I have other calibers I primarilly hunt with like a 30-06, a 35 Whelen, a 44 mag, and a 45-70. But if one can only afford one gun with a stash of ammo, military calibers IMHO should be the way to go.
