Home Forums Reloading Big Game Rifles WD 40 kill primers test

I have often heard that a shot of WD 40 will kill a primer. I recently had to deprime a bunch of WLP primers from some cases and saved the primers for a test. I soaked the primers in WD 40 for about a week.





I then loaded a dozen in some .44 Rem Mag cases.



I took them to the farm and put them in a Ruger .44Mag Vaquero to see if they would fire. Every one of the 12 primers fired.

I was surprised that they were still active after that long submerged in WD 40.
