I was thinking more on the order of primer/powder degradation/decay. A number of years ago, while living way out in the middle of nowhere I had about a decade of mistakes, or reloads I was not happy with. I had a fire pit that I dumped a coffee can into. Backing a safe distance, I lit the fire and it was a good show. I want to emphasize the fact I was literally miles from a road, path or occupied structure, no children or animals were within fragging range. No lead in the water issues, no groundwater or red squirrels were in danger. (I want to be eco-friendly [Politically correct] and most defiantly tongue in cheek)
I had this discussion the other day based on info I've gleaned over the years. The more arid the enviornment the better it is for ammo storage. In such areas even ammo stored in unsealed containers (i.e. exposed to the air, not in sardine can cases) can be good for 20+ years at the very least. I live in an ammo-killing enviornment....year-round humidity and a close proximity to the ocean. 5-10 years max is what I've seen for recommendations in an area like mine.
