You know those little boxes that the half-cases of defensive ammo ship in? What are they, about 8" on a side? I had one of those at the range at which I used to work on which I wrote "THE BOX OF SHAME" in Sharpie, and tossed the defective ammo that customers would bring off the range into the thing.
It needed to be emptied out more than once over a three-year period.
