Oil soked primers

[clum sum]

I have been told and read for years that oil was deadly to primers. I had some 357 loaded by someone, somewhere, no idea what bullet, what powder or how much. Pulled the bullets, used the powder to make a nice fire and soaked one hull with primer in Break Free CLP for two weeks. Loaded it in my old rugged Ruger,   pulled the trigger and it went pop. Should not the primmer have been killed?

I was once trying to deaden primers to use case heads as grip medalions in a sixgun. I  tried soaking them in oil for a week and still had about 50 percent of them that would go off. water actually worked better but then i found that after a couple weeks the water soaked ones would dry and about all would go off. I would have to guess though that a differnt oil might make a differnce. the only thing i tried was 556.
