I just started reloading and I had a good round of testing powder drops. I found my desired powder limit and made 200 rounds. They worked great the next day when I went to the range. The next time I went out (about 2 months later) they didn't work at all. Not even the primer detonated, which leads me to think it was the primers. I took the round apart, I definitely had powder. Any help?
