Gigantor - I said about a year ago that IMHO the best reserve currency for fools like us is 9mm, .22., .223, and.308 ammo.
Think about it. I lasts nearly forever, can be measured, can be traded for other goods, has inherent value and use, can be used in a variety of guns, can be divided into small quantities, etc.
I have been shooting for 18 years now. The cost of ammo has always been either steady or rising.
Ammo can be used in either a SHTF scenario or barted for water, food, or other staples.
