Question about ammo. How long does brass ammo, 9MM, .45 etc. and shot gun shells last in storage? Do they go bad, become unusable over time? I have plenty of firepower, but was wondering how long I could expect to be able to store the ammo.

I still shoot surplus ammo made in the 30’s.

If you keep it cool and dry, it should outlast you. There is 70 year old ammo being used today, and it works fine.
