I've got a copper streak on one of the lands of my Remington .223. I've hit it with Hoppes, Sweets, and JB bore paste...it still hangs on. The rifle shoots great, so I'm not super worried about it...but I'd still like it gone. What should I do...keep scrubbing?

Rifle is new...only 55 rounds down the pipe.

Cheers,
BongoBob

I have a .270 with a similar problem. Gunslick/Outers Foaming Bore Cleaner is what I use. Put the rifle into a muzzle down position with the bore on a rag, apply foaming bore cleaner as per instructions, leave overnight, find large blue stain on the rag the next morning and the barrel clear.
 
I had the same thing with a custom stainless barrel on my target rifle a few years ago. I would always get copper on one land. Never should have seen copper because I shoot moly coated bullets. Turns out the barrel was pooched about 8 inches from the muzzle. I wastes 2 years trying to get that thing to shoot as well as the last barrel that was on there.
 
amen

Amazing with the internet info available to us and so many are blind to KG-12.

Similar tests have been around on the web for a long time and gunnies still like to sweat and scrape bores.

The best thing about KG-12 is NO EFFORT! - Just windex(cheapest carbon cleaner)out the carbon , wet bore with KG-12 , soak overnight and 3 or 4 stokes the next day.

I shudder to think of all the wasted years of my sweat with JB paste. ;)

Very interesting thread Kombayotch. I've just cracked open a bottle of BBS that has sat in the cupboard for months. I might have to get some KG-12 now.
 
Use a new quality brush and JB Bore cleaner... patching JB isn't as effective. Then follow it with any copper solvent. Wipeout over night works...
 
Sweets will work, but it requires patience. You can increase the time it can work in the bore to half an hour if you plug the muzzle and chamber with wet patches to stop the airflow from dying it out which is what damages your barrel when you use an ammonia based solvent. I like Wipeout as its simple to foam the bore at bedtime and patch it out when I get up. JB and Kroil working in conjunction with one another has been a popular way of dealing with tough fouling for quite some time. Give the bore a good soaking in Kroil and allow it to stand for a while to give the oil time to get under the fouling then the JB on a tight fitting bore brush can strip it away more easily.

Once you get your bore clean, perhaps consider treating the bore and your bullets with moly. Its simple to apply without a making mess once you know the trick, and extends the number of rounds between cleanings.
 
Warning: don't try this on a match barrel!

Get the bore clean and consider fire lapping the barrel using a product like David Tubb's Final Polish System to make you bore smooth like a mirror.
Don't use it on a match barrel or a super shooting barrel but for a normal barrel that fouls it can do miracles, both in with fouling and accuracy.

If it shoots, who cares? Leave it. If it is in one one part of the barrel, it is likely there for a reason and that is most likely the poor quality if the Remington bore. That copper is only molecules thick, and likely fills-in an area of imperfection like spackle. If you clean it, It will only fill back in and likely be less accurate in the process.

Never had copper I couldn't clean with ammonia-based Sweets. I plug the bore with bore mops and leave it for a few hours. I turn the gun upside down for half the time whenever I am using liquid cleaners.
 
Thanks for all the feedback! Good info here for sure.

I'm going to shoot it some more. As I said, it shoots quite well. .50" - .75" five shot groups at 100 yrds with my first batch of handloads.

Next batch I will experiment with COAL and see what happens.

I'll worry about the copper streak again if accuracy starts to fall off.

Cheers,
Greg
