Interesting test. Thanks for doing it.

I thought the exterior of the primer in a loaded round would not be affected by oil. If oil migrates around the primer into the case and flash hole area, that is when it contact the open area of the primer and deadens it like your initial test. When the case is sealed the problem goes away. The military seals primers against water, oil and whatever for that reason.

Was it Remington or Winchester that used to manufacture "Oil Proof" (not sure if they used correct spelling of proof) ammunition. Again the tests made showed no migration of oil around the primer and no failures to fire.

Your test shows that with well sealed ammo, no worries.

Thanks for the test and the link.
And many thanks for The Box O'Truth (if you are the author). I've been reading TBoT since it started. Solid test data, even if limited, is better than all the guesses on the Internet.

Pretty sure SgtKnuckles is not Old_Painless. TBOT is great though.

No, I did not write the test... But I thought we all should read the Info in the Link...<:-)) I don't think any of us would go out of our way to Oil our Primers...<:-)) But thats whats nice about our Forum, in that it informs the New Noobs to Gunning the Do's & Don't's about the Care, and Feeding of a FireArm...<:-))

One of our own conducted various tests with various oils and water on primers. Before we consider the above as gospel one should read "Primers and oil" http://thehighroad.org/showthread.php?t=164849

I don't know about that test, but I was using penetrating oils like WD on steel shot shells to combat the rust from hunting the salt marshes. Now, too, I get 'em wet which never seemed to bother 'em, been getting shotgun shells wet for a long time, why I have to fight the rust.

Well, after several years of sitting up, I've had shotgun shells dud, but ya know what, the primer went off, but the powder didn't ignite. I'm thinking the oil got between the primer and the powder and deterred ignition. I never had a failure of a 3 or 4 year old round that had been drowned in marsh water, not a failure to fire, not until I started using the oils on 'em.

So, I think it's not so much that the primers will foul as that the powder between primer and powder fouls and won't fire. Pretty sickening when a nice bull sprig sets his wings into the dekes and the gun goes "pop" and the wad and shot charge falls out at your feet. Think of how sickening it would be to draw down and have to shoot and armed bad guy and the bullet sticks in the bore. I'd rather be safe than sorry. I'm careful with oils and don't over oil chambers and such. For carry, I clean the gun, wipe it down with some oil, clean off the excess before loading. Of course, cycling your carry ammo out once in a while helps prevent such failures, too. I like fresh ammo.

That's pretty much what I'm saying...You can do all the tests you want...But bet on the fact that a primer will survive. Never assume it is dead...I know of only two things that will kill a primer. One is to fire it and the other is water, but you have to wash the primer slurry out of the cup to insure it is dead.
