There has been a number of questions about how to de-activate a primer.
Our past experience showed that it all depends on the primer.Those available for us reloaders, some have a protective covbering that prevents oil from penetrating the compound to kill it.I am going to try this with some factory ammo. We have started with Fiocchi 9mm ammo.I have pulled the bullets out of 10 rounds, and squirted WD40 into each case to about half its capacity.
My intention is to see how long it take for the primers to die.Round 1 fired after 30 minutes of being soaked, no problem there at all. I will fire a couple today, noting the times. The rest I will leave, firing one every day. I will let you know how this works out.

Round 2 fired 2 hours after being soaked in WD40 fired, but sounded rather subdude.

Round 3 fired after 6 hours of soaking in WD40.Went off like the number 2.Next one will be fired after 24 hours.We selected WD40 because it is a penetrating oil, no other reason.
Round 4 still fired just like the previous one. Not with a full BANG, but still might ignite the powder.I have 6 more rounds to fire, which I will do each day.
Yesterday I also pulled bullets from Norma 9mm Para ammo.Fired one one hour later, and went off about half power.This morning, I fired one Fiocchi and one Norma.The Fiochi has been wet for 48 Hours, and the Norma 24 hours.The Fiochi went off with a louder bang than the Norma, despite being wet with WD 40 for twice as long!
Will fire the next ones tomorrow.

Well, apart from the original effect on the primers after a few hours, it seems things have stood still. Both the Fiocchi and Norm primers fired this morning. Once I am finished with these, I will try the same with primers that I have for large rifles.I have primers from Federal, Winchester, CCI and RWS. By the looks of things, the RWS do not seem to be sealed, so it will be interesting to see how they all perform.

This is getting interesting.The Fiocchi have been soaked for 8 days.
Still fire, but with a very much reduced report. The same with the Norma.

Well, it has been 20 days of them soaked in WD 40, they still fire, albight at much reduced power.So I thought I might try something else.I have deprimed 50 308 Winchester cases - I have plenty of these.I have marked each 25 of them separately, as I have Federal 210M and RWS 5341, just to see if there is a any difference in what happens.
I am going to soak 5 primed cases with each of the following:
1. Sea water.
2. Hoppe's lubricating oil.
3. Hoppes Elite Gun Cleaner.
4. Birchwood Casey Gun Scrubber solvent/degreaser.
5. Hoppe's # 9.
I will fire one of each every 24 hours.

Well, this certainly is an eye opener.
Here are the results of soaking the primed cases for 24 hours.
1. Hoppe's Lubricating oil - RWS, fired normally. Federal 210M , dead!
2. Hoppe's Elite Gun Cleaner - RWS, fired normally. Federal 210M, dead.
3. Hoppe's #9 - RWS, fired normally. Federal 210M, dead.
4. Birchwood Casey Scrubber - RWS, fired. Federal 210M, dead.
5. Sea water - RWS, fired. Federal 210M, fired.
So it seems sea water is the least effective primer killer!
And it depends on the make of the primer as well.
I will fire the rest of the RWS at 24 hour intervals, and the Federal with sea water as well.

48 hours later.
1. Hoppe's \lubricsting oil - RWS, fired normall. Federal 210M, dead
2. Hoppe's Elite Cleaner - RWS, dead. Federal 210M, dead
3. Hoppe's #9 - RWS, fired normally. Federal 210M, dead.
4. Birchwood Casey Scrubber - RWS, fired normally. FFederal 210m, fired normally.
5. Sea water - RWS, dead. Federal 210m, fired normally.
Now, I have to qualify what I mentioned above about "fired normally" as I am not sure the primer would have ignited the powder charge.
I could definitely hear a bang, and see smoke as I eject the case out. But, it is much less than a normal primed case.

Well, here is todays update.
72 hours after being soaked.
Ingredients as numbered above.
1. RWS Fired. Federal, dead.
2. RWS, dead. Federal, dead
3. RWS Fired. Federal, dead
4. RWS, fired. Federal fired.
5. RWS, fired. Federal dead.
Number 4 above with Birchwood casey, the liquid must have evaporated, as both primers went off with almost full force.
