Dreaded Carbon Ring

I have tried the C4 and while it is decent on carbon between the lands down the barrel I find it lacks on the carbon ring. After every range session I clean and soak the throat area with C4 then spin with a bronze brush. This seems to keep the ring under control but if it forms and hardens then the only way I have been able to remove it is with an abrasive and spinning a brush. JME
 
I have found wrapping some bronze wool around a Tipton nylon brush or a well worn bronze brush with even JB [lots] smeared over the bronze wool cleans hard carbon in the throat after 'just' 20 - 30 short strokes.

I say 'even JB' because Iosso and Flitz bore cleaner work much faster than JB when using a tight patch wrapped around a Parker Hale jag.

The only thing is, that brush/bronze wool gets really groody.
 
My personal experience is that I have had a bore scope for over 15 years. I inspect my chamber before I load before a match to insure there is no fouling or carbon ring to cause incorrect bullet measurements to the lands. I have found that there is always 2 places that fouling turns into a carbon ring. The first is the distance in between the end of your cartridge neck AOL and your chamber neck OAL. The 2nd, is at the throat area. As soon as a cartridge has been fired, the fouling is starting to be formed. Depending on powder, the rate of speed and heat from powder ignition and number of rounds fired this fouling starts to build up and eventually turns into carbon.. I have seen carbon rings after 50 rounds fired.

Right after a match or shooting multiple rounds, I do a quick cleaning with Bore Tech carbon remover. Then I apply a patch of Kroil penetrating oil down the barrel. I also leave a wet patch in the chamber throat area to soak until I have the proper time to clean and remove the carbon rings that are starting to build up.

When I start to clean the barrel thoroughly, I start with a Kroil penetrating oil wet patch to remove the material that it has loosen up since the last application. Then I review the area with a bore scope to determine how to proceed to remove everything left in the chamber neck, throat and barrel grooves. If it is bad enough, I have no problem using an oversize bronze brush to turn into the neck and throat area to break apart the carbon rings. They will actually break apart after the penetrating oil has penetrated the rings and helps loosen them from the barrel. After I break them up or they pulverize utilizing a bronze brush contact, I push that material out the barrel end and come back with a Bore Tech Caron remover patch to clean the bore. Then, I take a JB compound patch and make several ( at least 10) strokes to smooth bore all the way to muzzle. I then use 3 dry patches to dry out the bore and review with bore scope to confirm the bore is pristine clean and ready for throat bore erosion measurement and new load development.

I have found that using the Kroil " the penetrating oil that creeps" actually penetrates the bore and helps keeping the fouling to build up as hard.

I am sure there are other methodology efforts that work as well. This works for me.

Just my .02¢

Once you get rid of the ring, a tight patch with a generous amount of IOSSO spun around the throat area then short stroked down the barrel WHILE STILL WARM FROM SHOOTING works for me. Make sure to remove the Iosso with a wet patch or two and brushing again with your bore cleaner. Got to get it out before it gets hard, as you have found out.
I tried the blue Iosso brushes to apply the paste but the results were the same. Easier to throw away a patch than clean that nylon brush.

My barrels that don't collect copper, I put 2 Accelerator soaked patches thru. A 3rd is left just ahead of the bore guide(muzzle slightly lower than the action). 5-10 minutes soak. Patch is pushed thru. Good brush replaces the jag, a 1 second shot of free all(straw in place) in the muzzle. 5-10 strokes with the brush. Patch with free all, this patch will be black. Repeat the free all and brush/patch. Bore scope, most of my rifles will be CLEAN. I go back and forth between clean chamber/throat first or last. Copper removal adds steps, old hunting rifles from friends are the worst.
 
Barrel cleaning procedures, followed by the fearing of the carbon ring, has almost become a pagan religion.

At some point, I expect that there will be some involvement by someone sacrificing a live chicken.

I will say this. I've chambered about 300 barrels in the last 3 years and I dare you to scratch a stainless steel barrel with a copper and bronze brush. I dare you. Don't believe me? Take your bronze brush and put it in a drill and take one of your old barrels and see if you can scratch the outside. All you will do is leave a color that looks like copper. Because bronze cannot scratch steel. That's the idea of using bronze to clean barrels.

Stop reading everything on the internet and just go do it for yourself. Do that little test and you can see it for yourself. You can bear down pretty hard with a Scotch-Brite pad before you're going to start to cut stainless. And Scotch-Brite pads are made to cut steel. Bronze will not cut steel. End of story.

I believe this to be true. Too many top winning shooters & gunsmiths have eluded to the same facts over and over again.

I mean brother, at some point people are arguing over a physical impossibility.

It's like worrying about whether a stick of butter can scratch your frying pan.

It's like believing cow farts change of the weather. Like I said it's become kind of a weird pagan religion.

Good point.
The carbon between the end of the case neck and the end of the chamber neck I've found to be relatively easy to remove. Seems to be taken out with brushing with a bonze brush. I've not been thinking this was a 'carbon ring'. Maybe because I shoot an AR and always start cleaning with a one of those bronze bristle chamber brushes.

The ring at the very beginning of the throat is the one that I've found is tough and requires abrasives.
 
In a 6mm chamber, I use a new 25 cal bronze brush. I bought a 3 piece rod off of fleabay to use the tip rod in a cordless drill. With some wipe out on the tip of the brush, I insert it till I just feel it hit the end of the case mouth in the chamber, Then I spin it maybe 3-4 seconds and patch, then again if needed. I've seen the video of the guy spinning the brush in the bore like a mad man....I can't afford new barrels like he can. I did spin a bronze brush in an old barrels throat that was clean....there were very slight scratch marks...and that was only 3-4 seconds on a slow rpm....I'll keep being careful until the price of new barrels drop below 6-9 hundred dollars..?

My haters always do their best to watch everything I do and talk about me when I'm not around. While they are working a job they hate, I'm shooting all day. I guess I'd be mad if I were them too. What a blessing from God. Such an honor to be on peoples minds this much. This is my first post here in nearly 2 years. (any forums in near a year) Due to the prevalence of hateful spiteful people on forums, these just aren't nice places to be for anyone. I used to care what people thought, but that time is long gone. All the name calling only makes the people doing it smaller and smaller.

Haters, thanks for advertising for me and keeping my name in your head, in your mouth, and at your fingertips. Another blessing from God to have people so angry with the truth of what I do.

I think most people would be pretty happy with the level of performance I regularly achieve in our 22lr rifles. Over 9,000 rounds on this rifle in the video below without being cleaned. It has over 12,000 on it right now, and still has not been cleaned... and I went out and shot some flies with it just the other day. So while anonymous internet trolls are busy trying to tell people what I can't do... just remember, I'm always there proving it with live unedited video just like this. 22lr at 50yds. Anonymous attacks on the internet are worthless... and do nothing but make the people posting them feel worse and worse about themselves.

In the mean time, have some hot coals on your head. Try not to let it burn you up. ...and don't let this attention go to your head. I won't be responding.

And your rimfire experiences have what to do with this post? Are you saying he should never clean his center fire rifle - and that the doughnut is a figment of his imagination? Gimme as break.......

Wait, wait, wait. No haters:)

ETA. Is there a place in the video where he talks about carbon rings? I looked at the part where no targets were showing and didn't hear anything about cleaning or carbon rings.,

Not to mention he says there is no such thing as neck tension. It’s neck interference he claims and runs .003 in all his rifles. I knew from that single vid he was full of it
