So, with all of the vintage ammo threads and since I didn’t seem to get any answers I decided to start a thread on modern ammo storage. Assuming that you keep modern powders and primers in a good storage location how long would you suspect the ammo to last? I’ve read on here that some people are having issues with corrosion in less than 20-30 years. I’d suspect in ammo cans in a good storage location that ammo would last far longer than 20-30 years but since we can’t predict the future I don’t know. Anyone got any ideas on how long you could realistically store and use modern day ammo?
