Government Hording Hollow-Point Ammo?

I hope somebody here, can either acknowledge or refute the rumour I am ever increasingly hearing as I idly spend my day browsing the forums on the web, that the government is stockpiling hollow point ammunition ? why is the ammunition hollow point? is this not the type of ammo used to hunt deer and elk etc.? are they only supporting the ammunition manufacturers market? trying to prop up a depressed ammo market? when you can come acrooss .22 rounds locally the dealers want an arm and a leg for them.. even the wally world sporting goods dept. guy told me .22 rounds are not available due to the government buying them.. my take on the hollow point .308 rounds is they will need ammo at the FEMA Camp guardhouses and will need the field bosses armed in the fields to supervise us when were tending, planting, harvesting crops by hand
