I still think the government is behind it, spending huge sums of money they don't have on ammo they don't need.
You should be thankful the govt or military is doing just that. Without military surplus powder companies like Hodgdon would not exist in fact all the powder mills started and exist to supply the military. Right now the pecking order for supplies is controlled by contracts. You and I don't have a contract for powder and primers and all of us combined are a very small number collectively and because we are all so diverse in our wants and needs we are not easily catered to. In other words we don't have the horsepower to make things happen the way we would like. So Military contracts first, then law enforcement and other Govt agencies second, then wholesale factory ammo, then us.
The military has always maintained large ammo reserves for contingencies that can't be planned on. You can't all of a sudden order enough ammo to support some conflict the pops up nor can you expect Federal, Winchester, CCI or any of these companies to stand by and wait for a large order to come in. You have to build and groom your suppliers and the pipeline and that mean keeping enough product in the pipeline to keep the factories working. I have been reloading close to 45 years and have seen so many guys drop out of the sport of shooting during this time that I can't even imagine the count. All of a sudden guns and shooting are in big demand but for how long ? The military and law enforcement just keep buying
