I have seen references to people suggesting that in the event of a TEOTWAWKI that .22 LR would be used as money. After seeing what is happening with the present ammunition shortage I am a believer and I don't think it will just be .22 but all calibers and they will have values that rise and fall just like commodities such as gold and silver.
I am adjusting my storage plan to include more ammunition for trading stock but will wait until the prices regain normalcy before stocking up. I believe I will stock some of all the popular calibers, the ones no one can find now, even if I don't have guns that shoot them.
I assume factory ammo, ammo in spam cans, and hunting rounds will all be considered premium. As that gets used up then reloads will become the norm but will always be a question of who did the reloading.
It might be worth looking into primer and case sealant for extended storage.

It is a bit pricey so I need to do some research on alternates.
The new money! .22 LR standard velocity military surplus that the CMP sold last November for $150 a case delivered has sold on Gunbroker (same lot number) for as much as $655 a case delivered.
