After the thread at http://www.thehighroad.org/showthread.php?t=188291 I tried killing some primers. I had a loading block handy with 50 cases primed with Winchester Large Rifle primers, so I

- filled 10 cases with water and let them sit.

- filled 10 cases with water, let them sit for about 15 minutes, then dumped the water out and let them dry out for two days.

- filled 10 cases with strong soapy water (Ivory soap powder), dumped the soapy water out of 5 of them after about 15 minutes and let those dry, while leaving the soapy water in the other 5.

- squirted WD-40 into 5 cases.

- squirted Kroil into 5 cases. The next morning, I dumped the excess oil that was remaining in two of the five, both WD-40 and Kroil.

- squirted WD-40 into the loading block hole where two cases were sitting, same with the Kroil, and one with soapy water. This let those cases sit in those solvents for two days, primer in the solvent, but nothing inside the case.

That left me 5 cases that were "good",-- nothing done to them.

The "good" ones worked fine.

I fired 10 that were soaked in water, then let dry. 9 fired, one didn't. (I think ... read on) I fired 5 that had been soaked in soapy water and dried. All 5 fired.

I started firing the ones that were still soaking in water, soapy water, and in WD-40 and Kroil. None of the ones with WD-40 or Kroil still in the case went off. Of the 5 that had soapy water still in the case, none really fired, but 3 did something. All 10 of the ones with water still in them "did something", the same thing.

Those puzzled me. The primers that "did something" partially fired. They made a little "poof" sound, and there was some ejecta from the muzzle, although both the sound and the amount of ejecta were way less than a normal primer. But they did partially fire. They were not entirely dead, despite having been wet for two days, and still being wet.

The cases that had the primer end soaking in stuff for two days fired normally, as did the primers that hadn't been futzed with.

The one that had been soaked and dried that I marked as "didn't fire" might have "did something", but I was not at that point attuned to the "did something" sound.

So, I conclude that I owe Smokey Joe a beer or two, and that primers are a lot harder to kill than I thought. Maybe the only reliable way is to fire them. The only primers that seemed to have been killed were the ones still soaking in oil.

But now I won't feel quite so silly with my earmuffs, safety glasses, and a towel wrapped around my face when I deprime live primers.
 
Infidel,
Thank you. Guess you cannot trust every thing you read, meaning all the reloading books and manuals that I have read are telling you NOT to touch the primers with your fingers because the oil from your fingers will kill them. It’s Better to be safe then sorry.


whipper.
 
Priming compound is made wet, and rolled out like cookie dough before the priming pellets are punched out. After the compound has dried, then it becomes what we know as a primer. Getting it wet with water, as you've shown, will not kill the primer, because that's how it's made in the first place.

As you've found out, the only way to positively kill a primer is to shoot it, though I've used oil to make them safer to punch out in the past. I deprimed several thousand WW II 30-06 cases, with the corrosive primers crimped heavily in this way, and never had one detonate, even though they were deformed in pushing them out. I used a product called Engarde, which is a penetrating oil, and like the Kroil, didn't allow any of the primers to go off while still wet from the oil.

Back in the 1970's, I saw ammunition that wouldn't go off from being sprayed with WD-40 from the outside. It was a .38 revolver and the officer had sprayed his gun down with it during a rain storm, and then a couple weeks later went to the range for monthly qualification and the rounds wouldn't go off. All six of them had been "killed" by the WD-40.

My best advice is to keep any penetrating oil away from your ammunition, "just in case".

Hope this helps.

Thanks for the report. That's one of those things I have wondered about but never got around to trying.

Re: "wet" priming compound. Is water what makes it wet or a solvent? I'm thinking if it is a solvent, maybe we could deactivate primers by soaking them in that.
 
Try it and see!

Infidel--There's nothing, NOTHING, like trying out an hypothesis yourself! Good on you! I applaud yr scientific approach, and also yr scientific reporting of yr results.

As to the beers--Consider that virtue is its own reward. :)

Safety practices are NEVER a bad thing. Caution is never wasted.

Thx again for reporting!
 
I really thought that water in the case would do the trick, so this was a real learning experience for me. I'm pondering the hammer thing....
 
Don't listen to Grump...He has only one eye and 1 1/2 ears left

Hey, I resemble that remark!!

Truth be told, I've worn glasses forever and have enjoyed great benefits from the shielding effect. And daddy taught me to use ear plugs. Even used 'em at a few concerts I attended. So, in fact, you'll find few BANG!! enthusiasts with hearing as good as mine. Guns, firecrackers, car wrecks, paper sacks, I love them all!

Did you know how great your hearing protection can be while hammering a full roll of capgun caps with one hand, and plugging your right ear with your left index finger???? The left shoulder just comes up so conveniently to the left ear....
