On another post the discussion about killing primers was locked . I just want to add my experience. Some months ago I withdrew ten primed cases in 38 special from my reloading stock and gave them a squirt of WD40. Last week I put them through my Winchester 94 in .38 /357. Eight out of the ten went off.Of the other two one went off on second hit.
The primers were either PPU or S&B i know not which but they resisted the effects of WD40. Old primers may have succumed but modern primers are better sealed. I intend to persue this by boiling when I get the time but don’t think that a drop of oil will kill a modern primer because it wont.
I would welcome similar experimentation from some of the other serious members with a vested interest to reach a concensus. This is something we need to get wrapped up tight. For all sorts of reasons but self protection primarily.
