Curious about ammo in ammo cans in stored in dehumidified gun safe in garage safe.
Have some 10 years old but curious about keeping them in house in ammo cans vs the dehumidified gun safe in garage.
Any difference?

I have a lifetime supply of 7.62X39 from the 80's when it was cheaper the .22LR and came in oil paper packages.. So far that everly decreasingly supply has lived from West Texas, to Central Idaho, to 9,000 feet in Colorado and now back to Texas. All spending years in each location all stored with little thought of conditions other than in metal cans under a roof. It still functions as it should with one MAYBE 2-3 times seeing pressure signs and that was in a suppressed bolt gun. I can not speak for any other ammo and maybe the oil paper has something to do with it but no issues here.

Nitroglycerin is not stable long-term. Plenty of scary incidents with old dynamite.

Not completly off topic, but for about 20 years I was the Lead Blaster for the National Forest that I worked on. One time a hiker reported finding an old chest freezer full of dynamite up by some old mines in the Forest south of Livingston, MT.

The District Blaster and I went up there to remove the hazzard. The old freezer had 2 1/2 cases of old nitroglycerin dynamite dated 1947 in it. The Nitro had leached out of the dynamite sticks and there was about 1/2" of pale brown "jello" under the dynamite boxes. There was also a dozen or more blasting caps in a shelf above the boxes.

I took several pictures of the freezer and dynamite, then set my camera on a rock behind me. As I was carefully moving the blasting caps and loose sticks of powder together, my camera started going off my itself. Click...bzzz...click...bzzz...etc. Talk about a quick scare!

So I got all of the old explosives bunched together in the freezer, and put a 1 lb Kine Pac two component explosive with an extra long fuse on it.

We backed off well beyond the 500' recommended distance from the site, and after the explosives detonated, we found parts of that freezer 5 switchbacks down the mountain.

Man, that is some serious nightmare fuel right there. Funny as hell about the camera going off though.
