Stubborn Copper Fouling

CajunBass · June 5, 2013, 04:26 PM

I've got a 1924 Parker Trogan that a previous owner must have shot copper plated shot through. The Lord only knows how long it's been in there.

I've been plugging along with it using Shooters Choice but it's slow going.

Got any other ideas?

KG-12

There is no other.

I hear that M-Pro 7 works well too.

Is it hurting anything?

If not, why so much emphasis on removing it?

Thanks Brian. I'll look for that the next time I'm at the LGS.

Is it hurting anything? Probably not. It's just something I started doing, and want to get it done. That's all.

Barnes CR-10 ....works real well on very stubborn spots.

Industrial strength ammonia will remove all of it. It will even remove copper the best copper cleaners leave behind but it will also remove bluing instantly.

Ball grinder and a high speed source will also take care of it.

My dad chucks bronze brushes in a cordless drill for his smooth-bores. It doesn't seem to hurt anything but it sure feels wrong.

Been doing that myself.

After a few hundred hand passes through the barrel, suddenly it doesn't seem so wrong.

Hmm. These guys would disagree.

Quote:

the bore is not protected from pittling and corrosion because the oil cannot get to the steel because of the copper "plating"

Quote:

A friend of mine is a metalergist, he says that two different metals like copper and barrel steel left unattended, will cause electrolisis and the steel will be the one that suffers causing pitting.

Well, just to fill everyone in, I've gotten most of it, and am working on the rest.

You should see the bright shiney bores.

FoghornLeghorn · June 10, 2013, 11:06 AM

How did you do it?

GunXpatriot · June 10, 2013, 03:54 PM

Butch's Bore Shine? Used it in the .30-06, seemed to get the job done. You're going to need something volatile to get fouling that old out of the bore.

Good to see you made progress with it.

Shooters Choice (I already had it) on a patch...soak...brush on a drill...shooters choice on a patch...dry patch...

Repeat....often.
