SUCCESS at Last - Carbon in throat removal

Silver $$ Contributor
This is a more general question because I have this in all of my barrels. The throats seem to all have a sheen of carbon in their throats. I normally use Montana Extreme bore solvent which is supposed to get copper and carbon out of the barrel. Copper yes, carbon nope. I also have used JB Bore Paste and Bore Brite. Neither seem to touch it.

So I tried Bore tech carbon remover. Nope. I did a search on here about carbon removal and every body talked about KG-1 so I got some of it. I tried following the directions, nope still there. The first patch did have a graying to it but the rest of the tries all were white. Nope. I tried soaking it over night, no help.

Here are some pictures of my 6x47L barrel at 650 rounds. I don't hot rod my loads since F-Class being known distance don't have to go as fast as you can get, just accurate.

First picture is from the mouth through to the leade.

The next is a few inches further down the barrel

This is the hazard of getting a bore scope, but I digress.

So I am coming to all of you. Am I paranoid about the carbon and just ignore it. I am sure that all of my previous barrel were as bad or worse than this. It is even worse in my 22 RF barrels. Or is there something that I can use to get it out. Kroil doesn't seem to get under it. Further down the barrel from about 5 inches to the muzzle there is just shinny stainless.

I am baffled. Thanks in advance

When you used JB, how did you apply/use it?

I've found I need a patch wrapped around a jag so it fits pretty tight - and, it takes a LOT of patches and strokes to make a dent. For example, to notice a difference in the first picture, I'd expect to go through at least 5 patches with 10 cycles each - and probably need 10 patches, 10 cycles each.
 
It's the ring that forms at the very beginning of the throat ( where the case neck ends) that causes problems. I don't sweat a bit of carbon left in the rifling crevices. I have always controlled it with Iosso bore paste on a tight patch- spinning it around when the patch first gets resistance then short stoking it the next 10", then push out the muzzle.
 
In your situation, I would use this on a tight punch type of jag, 3 patches and check the results.

you have to be careful when using abrasives, you can open up the throat dia.


Often soaking the barrel in Kroil, using new brushes will get carbon out, but how much depends on how hard it is cooked on. Carbon will get so hard that you will never get it out.

I have corked barrels at the muzzle, filled the bore full of a penetrating oil called free all and let them soak for up to 6 Weeks. Drain the oil, then brush with a new brush, 4 dry patches, examine with bore scope, repeat up to 4 times, and then JB will get out the tiny bit of the remainder. New bronze bristle brush with less than 50 strokes on it is critical.

The only carbon I go after is the ring in the throat at the end of the case.

The stuff in the grooves can only be removed with JB Bore Paste.

I use my old bronze brushes to apply the Flitz. I like that even better than the nylon ones. I have done barrel after barrel now. All nice and clean.

ONLY USE BRONZE CORE BRUSHES. The bristles won't hurt your barrel, but the stupid BASE of the brush sure will!!!

Free All is good stuff bro. You can get it at O'reillys and it is the most invasive penetrating oil I have ever used.

People ruin more barrels babying their cleaning regimen than they do cleaning them. From my experience... people have no idea what it takes to get a barrel clean once it ihas been neglected with ineffective cleaning practices for some length of time.

This is a Gem of Wisdom on practical cleaning of hard carboned barrels. P. dog shooting will teach a guy a lot when it comes to gun cleaning.
 
I've found that it takes more than just patches. I've had good luck with some CRC GDI IVD intake valve cleaner and a bronze brush. Makes quick work of it. For really neglected carbon buildup, I follow that with some Remington 40X bore cleaner, which is akin to JB paste suspended in oil, and a bronze brush to knock loose the remaining crud. In either case, follow up with a good bore cleaning solvent and a few patches. Midway had the Rem 40X on sale for about a month. Looks like they still do.

You can also make your own slurry with JB compound and some light oil. I have used Kroil as the carrier.

For the carbon ring, I'll dip the end of a mop with a concentrated solution of Lemi Shine and put it into the throat letting is soak for a time (like 15 min or so), then rotate it some. If some stubborn carbon remains, a bore bush wrapped with a patch soaked with Flitz and a few short strokes for the throat area cleans it right up.

I will tell you what will teach a person to clean their barrels...

Not have enough money to buy another one...

In other words have a barrel that is "shot out" and say, "I am going to clean it down to the steel. I am either going to FIX IT or ruin it... I have not ruined one yet. FIXED SEVERAL. About 1500 rounds they just stop shooting... hmmm. I need a new barrel!!!

Nope. Probably dirty.

Tubb TMS bullets is the other key. Love those things.

How much throat do these TMS bullets use?
 
I am constantly surprised at the number of people who do not like to clean and just will not clean. Their barrel gets fouled and ruined, their response, "I JUST CAN NOT BELIEVE IT"......while looking at pictures on a lap top from Teslong!
 
Thanks to all of you who have responded. I guess while I thought I was doing a good job, I wasn't be aggressive enough. So I am going to take you-all's advice and step it up. I do have a tube of Flitz, but I don't have any bronze brushes so I need to make a run to a gunshop and get some.

I will also get some Free All to see what happens with it.

For the way I do JB, I first saturate the bore with Kroil, let stand for at least 3 hours and sometimes over night, them put on a patch on a brush I have reserved for this purpose that has all of the bristles filled in with patch remnants so the new patch is held against the lands and grooves. I typically take about 5 full length passes and then about 15 12 inch passes concentrating on the throat. Guess I am only touching the surface :-(

I'll go to work once I assemble what I need and let you know the results.

And my wife thinks I am OCD about cleaning my barrels. Wait till she sees this new regimen she will be calling in the guys with the white coats

Soooo, you have NEVER brushed then?
 
Take a bronze brush using kroil or Free All as a lube and run that brush 60 strokes full length of the barrel. Then add Flitz to the brush and run that another 30 strokes. Then do 20 strokes with Kroil and the brush again.

You should have big puddles off black stuff coming out of both ends of the barrel. Then patch with gun cleaner or lighter fluid until clear. Then borescope.

Here is video of my Rock Creek 6br which looked worse than yours after 1500 rounds of Reloader 15.
