The Ammunition Accountability Act states that manufacturers of ammunition and/or primers should have all products stamped with an expiration date or the maximum duration that the ammunition is still be able to fire. This is to safeguard both consumers and manufacturers of liability and/or danger.

No, there is no "expiration date" on ammo. Ammunition will last indefinitely if kept clean and most especially dry. Get an ammo can or dry box with a seal and store it in a cool, dry place and it will last for decades.
