Here, too--I've deprimed live primers and re-seated them, and they all went bang with results not observably different from first-time primers. If you take your time they don't go off, and if they do go off it's no big deal.
Back when I was reloading with a Lee hammer-it-in kit, is the only time I ever popped a primer while seating it, which was no big deal. "BANG!" and a little smoke comes up around your hand which is holding the die over the brass and primer seater. Drive out the primer with the decapping rod, resize the case, reprime the case--more gently this time--and reload as usual. That happened, oh, perhaps 3-4 times, over several years, before I got hold of a used Rock Chucker press.
BTW, if you choose not to re-use the removed primers, oil will NOT reliably deactivate 100% of them. This has been tested to death, and argued to death previously. No household chemical will kill 100% of your primers, none. All the oil is doing, Steel Talon, is making you feel better about putting the discarded primers in the trash. Primers are killed 100% by only 2 things: Heat, or Percussion. A fire would do it--NOT RECOMMENDED!!! Or put each one on a rock and hit it with a hammer. Using hand/eye/ear protection of course.
Please don't lets re-argue the issue of killing unwanted primers--Please. It's all been said and done already.
