I'd consider a stockpile to be more than you'd use in several years in a particular caliber.
How much that is, depends on how much you shoot. I've know some hunters that would take years to go through a single 20 round round box. So for them I guess a box is plenty, and two boxes would be a stockpile.
Then again, I know a couple of guys that shoot almost every week, and attend at least one (and sometimes several) high round count classes each year. For them, 1,000 rounds would not be near enough - and 10,000 might not last a year. A stockpile for them might need to be 30,000 rounds - or more. Maybe much more
Of course, with the value of the dollar plunging, you might want a stockpile big enough to supply your shooting needs for the foreseeable future (while ammo is still available for a price someone other than Bill Gates can afford).
