Cool, dark, and dry are the optimal conditions for ammo storage. I've known many competition shooters who stored their ammo in old refrigerators and never reported any problems. Around 1977 while at Ft. Leonard Wood, we found an old 1911 that had been left in a desk drawer in an old building. The ammo in the magazines had a 1943 dated headstamp, and every round fired without any problems.

When my present fridge dies it will be for gun powder storage.
