Does ammo ever go bad

brass shelled ammo doesn't go bad because the powder is safe from the elements

having said that, .22 ammo is dropping in prices again, looking at that stuff I would consider it to be worth 6-7 cents per round so if he has 25 boxes your looking at roughly 825 dollars worth of ammo

come to think of it, feel free to send me a few boxes of it when you send out that oilslinger to me
