Touching primers with fingers?

[wyt_tail]

I know a guy on another B.B. that actually tested to see how far one could go to ruin a primer (neutralize it). He used water, oil, WD-40, solvent, etc. This was done by soaking for exteneded periods. Most still fired so I wouldn't worry too much about oils from the skin. I always handle primers with my bare hands but do wash them before any priming operations.
