I know this is an old thread , but how much “old ammo” you reckon is “depleting” as the world turns? If memory serves me? there were plenty of conflicts to use this , long gone, ammo before the “expiration date” . Maybe we need a US Waste Division if it’s too much wook to bookkeep?..they could redesignate the ATF? I know those 30mm Gotcha’s would come in handy now.
