Unclenick, if I'm not mistaken, you had once mentioned, on another post on this subject, that plain water could be counted on to deactivate primers such as those being discussed. Since, then, I just use an empty Hodgdon powder bottle half-filled with water and drop damaged or primers that failed to fire in that container.
I suspect I should pull one or two out, reseat if possible, and see they go off when fired but I never get around to it.
