Ammo that expires?!

[u/ComfortableWaltz7053]

I recently heard a rumor that they're going to start making ammo that expires after a certain amount of time?

I was told about 4 years, would be the new shelf life and that the primer was going to be designed to only last a certain amount of time. Has anyone else heard this? Is there any truth to it? I would love to at least know where the rumors come from.

After looking it up I'm not the only person who's heard this but I didn't find much information on it.

I have heard that same rumor since Obama took office with nothing to back it up just hearsay
