Removing lead with mercury?

Post by Redleaf » Wed May 06, 2009 4:38 pm

I've read that mercury was used to de-lead barrels but cant find anything specific about how it was done. Anyone ever done this or know exactly how it was done?

Like many, I get it done with a tight patch and Kroil, so I don't have any experience with the mercury method. From the little I've heard about it, I have the impression it takes a lot of mercury...enough to fill the bore...but that's just a guess.

I tried it once a looooooong time ago on a heavily leaded .38 Special. It didn't work very well. Besides that, mercury seems to be a no-no these days. Worse then lead.

Get a Foul Out electrochemical bore cleaner from Outers. It will safely clean every trace of lead out of your bore if you correctly follow the instructions.

You plug one end of the barrel, pour in a small amount of mercury and then plug the other end. Then just shake it like a spray paint can for a minute. Then unplug one end and pour out the mercury.

And remember - You Can Die from Mercury fumes and absorption!

Apparently, this treatment goes back a ways. In 1892, A.C. Gould, in his book "Modern American Rifles" wrote: "If lead accumulates in the barrels, procure some quicksilver, and, after corking one end of barrel, pour the mercury in, and roll it back and forth. The lead will amalgamate with the quicksilver, and thus be largely or wholly removed."

I tried it with an adjustable bullet mould just to see if it works , and while it took some of the ring off it didnt do as good of job as I thought it would , you could see the lead mix with the mercury as it got a different sheen to it but even scrubbing with a stick in the mercury it didnt clean it all off ,I even let it stand on the lead ring for a few hours. believe there are better and safer ways to remove the lead , and turpentine gets my vote..or kroil ...................Dean

I recently tried it too, and my results were not worth a warm ball of spit. First attempt, I just plugged the chamber and poured in what I think was about three or four inches in the bore and tilted the rifle back and forth til my arm got tired,(about 4 or5 minutes) then let it sit for about 10 minutes. Nothing! Then I filled the bore with mercury and let it stand for about three hours. Got some gray streaks on the patch that time, but when I soaked it overnight with solvent and ran more patches through it, I got out streaks of lead. So, seems like de-leading a bore with mercury is just another old wives tale. Unless there's some technique involved that we dont know about.
When yall use turpentine, whats your method? Do you let it soak? How long?

Just wet the patch with turpentine and run it thru the bore on a jag. The lead that will come out on that patch will astonish you. Follow up with a few dry patches, and then hit it with the turpentine patch again , repeat until the gunk quits coming.

I wonder if I were to give some people I know a dose of tuprtentine if it would get the lead out of their butts?

Mix 50/50 hydrogen peroxide and white vinegar. Plug the end of the barrel and stand the rifle up, pour in the mix till it fills the barrel. Let sit for 15 minutes, no longer, then remove the plug and watch the lead pour out. Pour hot water down the barrel to stop the chemical reaction. Clean as normal. Repeat as necessary. I have never left the mix in longer than 15 minutes as it was suggested it could have a bad effect on the barrel.
Oil the bore after cleaning while it's still warm, and that will re-treat the bore.
