I have spent as lot of my recent writing effort casting doubt on some of cast bullet shooters cherished beliefs and rules and acting disrespectful to some bits of our time honored conventional wisdom. So when I saw the post below I thought I would paste it here to shake yet another bit of conventional wisdom.
The post came in response to another post by “Lee” issuing a dire warning that WD40 was “one of the worst” things for ruining primers.
“Lee, I am going to second zippy's post. Part of my practice routine has been for years to load 5 rounds with completely dead primers out of each 100 loaded. A few years ago I was able to buy a 1,000 empty primer cups from Winchester. After I had used all of these up, now they will not sell me empty cups. So I went about killing some primers. I have tried every concoction I could think of straight WD40 soaked primers for a week that didn't work so I soaked them for a month they are after that month just as good as new. I have tried soaking some as long as 6 weeks in Alcohol and WD40, Mobile 1 synthetic oil and Alcohol, lard, grease (several kinds), hydraulic oil, Kroil, PB Blaster, Nut Buster penetrating oil, anti freeze, and several others as well. All of these treatments and the primers still go bang. The only thing I have found to render them inert is to remove the anvil. For me the old story that WD40 ruins primers is just as zippy said and old wives tale.” Roland Once again, this shows that it is a good idea to be skeptical and test to see for yourself instead of just accepting something because it sounds logical.
