Copper removal from used gun

[KR260]

Bore Tech Eliminator works great. Use their proof positive jags so you don't get a false reading from a brass jag. I use that and their nylon brushes.

Do what Rosebud said, shoot it, some copper is good!

If you are working indoors and Cant Use Amonia smelly stuff,
KG 12 Copper Solvent has worked rather well for me.

Try patch out. I did some testing with butches and sweets. Patch out did better i think. Thanks

From the description you make it sound very much like a new rifle - and considering you said no scope has been mounted, I can't see how what you think is copper on the rifling is actually copper. I just hope you are not chaising a ghost. I'd follow the advice above and install a scope and go shoot it. Then see what you have.

Get boretech eliminator, boretech nylon brush, and one of their jags. With the other harsh cleaner here you CAN ruin your barrel. With boretech you cannot and I have used both Boretech and Barnes ammonia based cleaner. Very little difference in effectiveness.

Run 2-3 wet patches and run the brush 4-5 times also with solvent. After than run a wet patch or two every 15 min for an hour. After than run dry patches and with the amount present I'd expect it all to be gone. You CANNOT damage your bore with boretech.

All that said I'd shoot it first but I'd get the boretech stuff for when the accuracy falls off due to EXCESSIVE copper fouling. Being a new barrel it could be 5 rounds but if it's got a good surface finish it may be 500. Let the target tell the tale.

Just FYI, Kroil, can remove bluing as well as vinegar. The name brands mentioned are all good, 10x the money but good. When it comes to real cleaning, ammonia (I use sweets) for copper and CLR (calcium lime rust remover) best carbon cleaner you'll ever use and at $7.00, you can't go wrong. Now, you have to clean correctly, and clean up up after these products but there are plenty of places that tell you how to do that.

For applications like this, a couple passes of JB usually works for me. However, I find that the extra cleaning with JB doesn't do anything for the accuracy of the gun. I only care about getting it spotless when I put a gun in long term storage.

I used to clean barrels zealously, not so much now as I live in a dry climate and keep everything well oiled. The only time I try to get all copper out of a bore is if I'm shooting mono's or AccuBonds. Other than that a decent cleaning while breaking in and then just regular cleaning and oil. YMMV.

I would give Sweet's a go. Leave it in once foamed up with a LOOSE patch or nylon brush, for 15 minutes. Do this several times if blue keeps coming out.
Follow by JB to get any remaining carbon under where the copper was.
Always swab out with alcohol based solvent like Methylated spirits after using Sweet's.
Always swab out with a Petroleum based solvent after using JB. I like Carbie Kleen or Brake Kleen.
Follow with a LIGHT coat of oil, but NEVER shoot a rifle with an oily bore/chamber.
Swab them out before shooting.

Cheers.

any good high ammonia bore cleaner lots of wet patches then some either IOSSO or JB 's compound oversized nylon brush and lots of strolls with the brush more wet patches then dry bore take a flashlight and look in muzzle. I disagree with the bronze brushes as the chemical will dissolve them as well. Oh and repeat if copper is still present. My 2 pennies

I found Gunslick foam worked the best on copper, but it's discontinued. Maybe another foam brand will work well. With JB's I preferred using a jag with a good fitting patch. And a good quality new bronze brush can work well without copper solvent. At least to scratch the surface to allow the copper solvents to work after scrubbing.

I use Barnes CR-10 and it has always got the copper out and does turn patches blue although the odor isn't pleasant. I do as others have suggested and shoot it and see how it does. If it's a shooter then you may just want to leave it alone.

Doesn't Brake Clean have chlorine in it? Bad to leave in barrel? Carb Clean is ok no chlorine...

Another vote for wipe out and the accelerator and you definitely will be chasing your tail if you use a bronze brush or bronze jag. They will leave blue on the patch and you will think it is the barrel.

If you want to test to see what actually works and what doesn't, get a piece of copper pipe and take some of the solvent, put it on a patch and see how fast it transfers the copper from the pipe to the patch. Or use a penny, they are copper clad.
