Ok, I figure the answer is toss them, but here goes. I'm just getting back into reloading after about 12 years. When I was digging around in one of those rented storage buildings to find my Dillon press, I found that my wife had put a box of primers (5,000 with only a few missing) in the shed with the reloading equipment. So, is it safe to use the primers after being exposed to 12 Arkansas summers (often 100*+ and high humidity, especially in metal shed)? Should I use these or toss them? If I toss them, what's the proper way to dispose of bulk primers.
