I do agree with the other comment that the large ammunition purchases being made are 1) to lessen citizens' ability to get ammo and 2) for the gov't to use on the people within 10 years, if we make it that far.
Term 2 for 0bama is about gun confiscation and controlling Americans with insane regulations "for the Earth's sake". It's all about destruction and control.. 0bamacare will be disastrous and term 2 'climate change' regulations will be the final nail in Uncle Sam's coffin.
