I used to put some WD-40 on them because I heard that would deactivate them. But I never tested them to check.
When this topic has come up before about using oil or a penetrating oil to deaden, I always ask if anyone checked to see if it really did work. And to date, I have never gotten a reply that confirmed it worked.
So for all the folks that responded that they did this, did you ever check them?
Yep, one week later 50% fired with a pzzf and 50% went Bang. I don't trust WD40 as a deactivator of primers.
