If you are going to stockpile 22 LR ammo for after the Apocalypse, get yourself one of these:
https://en.wikipedia.org/wiki/American-180That’ll use up your stock pretty quick.
Heh. As one wag put it: The American Arms 180: The gun you load all week, and shoot on Sunday. 
In short, you can’t use up your stocks with that, because you’re spending all your time reloading it. 
During the Great American .22 Round Shortage, I discovered an interesting variant of .22 ammunition that has no powder, just the primer. Made by Aquila or something like that. It’s still dangerous, and will punch a hole through cans but is powered down enough to shoot indoors with a suitable backstop. Also good for quietly dispatching vermin and other critters in the barn or a more urban situation so as not to spook the womenfolk or horses.
“Colibri”
There’s also Super Colibri, which contains a limited amount of power.
Also available are .22Short (limited powder, many semi-autos won’t safely chamber), and CB & BB Caps (no powder, VERY tiny, safe in only specific weapons).
Even the dimminutive CB and BB Caps are serious business. I have over my shoulder here a 22 rimfire trap, into which I’ve also placed a 350-page phonebook (yes, those can still be found) as a muffler / noise reducer*. The center of the book is shredded by… CB Caps.
So - yes. Colibri rounds are dangerous.
But I seriously advise that you use anything else if you mean to shoot something living. 'Cause they’ll hurt, but won’t kill much.
Or a little easier to acquire, a double barrel 10/22 gatling gun:
Fun? Yes. Gimmick? Absolutely.
