I figured that running the press would be a good chore to get out of the way for the holiday.
Just a few minutes ago, the press suddenly stopped seating primers properly.
After stopping what I was doing, clearing the plate of rounds, and taking some time to investigate, I found a primer stuck to the bottom of the shell plate platform.
Seemingly in defiance of gravity, it wasn’t even jammed on anything. Tapping it with my finger sent it scurrying off for some dusty corner of the basement.
