MD - military ammo is lifed and can’t be used after its use by date (even though it’s still perfectly good). When I was in Afghanistan in 2010 the UK ATOs blew up a batch of lifted ammo of various natures and there must have been plenty of it as it nearly blew the roof off our building from 3Km away. A bolt fell from the roof and loads of dust and shit fell down too. I’m guessing the US do the same, so stocks aren’t likely to sit around for decades.
