Again, wrong. Ammo is not dangerous in a fire: [VIDEO] As for humidity, I think you would be surprised. Much of Appalachia and the East Coast have high humidity levels (typically 70-90% during summer IIRC) and I've never found ammo damaged by humidity there. I've shot 25 year old ammo that was put in an ammo can and dumped in a hiding spot near a pond (so, very high humidity) and had no issues shooting with it. Even if the ammo is stored in the manufacturer's cardboard box, I wouldn't worry about humidity damage unless average levels are over 85 or 90%. Water damage is a different matter, but I don't have any experience with that.

Even if it does go off, as long as the rounds are not chambered it's really not that big of a deal. [VIDEO]

Ammo cooking off in a fire sounds dramatic but isn't particularly dangerous [0], unless of course a loaded gun is burning. In the OP's position it would be really low on my list of priorities. [0]: [VIDEO] (skip to about 13 min)
