Remington model 700 LH barrel crud.


March 6, 2012, 08:04 PM
I have a 1981 Remington model 700 LH 30-06. This is my main hunting rifle and I can't seem to get the barrel clean. I've cleaned it over and over and still get black on my patches. I've been using Hoppies 9 with brass brushes for years. My other rifles are just fine, I can run the brushes and patches through them just a few times and they're clean. I tried again the other day and still more black on the patches. The gun remains accurate. Any ideas?

I'm thinking you've got some copper built up in the barrel. It doesn't always come out with Hoppes. Hoppes does have a copper solvent Benchrest 9. But I like Ed's Red, it works well and is economical too boot.

Another possibility is that the brass brush bristles are rubbing off on the barrel. Try cleaning with only patches (or a nylon brush).

The way to tell if it's copper build up is to leave the Hoppes in the barrel overnight and look for green the next day.

CR-10 or any of the stronger solvents will also show green. Use a plastic jag or a steel loop. Otherwise the brass jag will leave green on the patch.

Something to try thats a bit easier on the barrel is Kroil oil. Soak and set over night, scrub with a bronse brush and then a nylon brush and patch.

I had an old milsurp rifle like that I had gotten at a pawn shop. "It was full of copper fouling" I used several treatments of that foaming bore cleaner, with patches. I finally got it to the point they came out clean. I lube'd it up good with clp and couldn't believe how shiney the bore was when I got finished.

Try some Butch's Bore shine and JB bore paste

Also, Wally World sells some Remington Bore cleaner. Place a cleaning patch on a brush and apply the bore cleaner to the patch. Run it through the bore about 10 times. Run a dry patch followed by a solvent patch. Repeat the brush/patch bore cleaner again. This should have gotten all the copper out. Repeat 1-2x more for a really bad copper build up. I did this 2x to a Mauser MkX in .270 I recently aquired. It was sold new in '70's and has apparantly not been shot much (but hunted a lot...). It cleaned up very easily with 2x application of the Remington bore cleaner.
It works more or less the same as the JB bore cleaner......
