Best carbon ring solvent??

Hello guys,
I have a couple rifles that I get a carbon ring in from time to time. I have used GM top engine cleaner and it works well #1050002. I ran out and went to get more. They have changed the bottle and the number. Its now called upper engine and fuel injector cleaner #88861803. My question is is it the same... The bottle is different looking and costs more $23 and change. Or is there a another solvent that works just as well and is cheaper. Seamfoam or the like. Thanks, Matt
 
The new stuff is not the same as GM TEC.

I've never been successful removing the carbon ring with only chemical means.

I use my normal carbon cleaner and a short-handled, non-rotating rod with an over-sized brush using a twisting action.
 
There is huge freaking difference between removing normal carbon from the bore and removing a built-up carbon ring in the throat.
 
I would soak them with solvent over night to make it soft and loose by itself.

Give a test with Butch's Bore Shine.



M-Pro 7 Bore Gel also a good for remove carbon residue. I use it and easily brush of those carbon ring on Muzzle brake.
 
I recently had a carbon ring build up in my Light Gun and heard about Kerrn made by the kroil people and got a hold of some. It is used to dissolve carbon build ups in engines. I soaked my chamber with it and It actually softened it up and with a brush and patch I was able to remove it. do not know if it is the magic pill but it worked for me.

KG-1 removes carbon better than anything I have used.
I'll second this however I can't say that I ever experienced the dreaded "Carbon Ring". I rarely go over 25 rounds between cleaning with KG Carbon and Copper solvents and perhaps this is why I don't see them, JMHO
Borescope is on the "want list" but when I see the price I think barrels or optics. :-[
 
Guys a carbon ring is not like normal carbon. I have been shooting and reloading for over 55 years and only had one. It builds up between the mouth of the neck of the case and the neck chamber junction. It stops the case from sealing upon ignition. It is some hard stuff to get out.
 
I expand neck of a ruined case, cut it off at shoulder, super-glue onto end of wood dowel, notch rim with cut-off disc in Dremel, insert into chamber, twist a coupla times and voila! no carbon ring!

Very cheap fix.

IMO, what we have in this thread are comments about two different things, a buildup of powder fouling at the end of the neck portion of the chamber, back in what I have called the "dirty little corner" right where the parallel part of the neck part of the chamber ends, and a ring of hard carbon that usually starts somewhere just forward of that position, and which I have never seen any solvent touch, only abrasives such as IOSSO. Hard carbon is powder fouling that has become compressed by pressure into something that solvents and brushes cannot remove. As far as removing a ring with a specially prepared case goes, the area that it would need to be removed from is smaller than the diameter of a fired case's neck. I think that the poster's idea is a fine one for getting back in that corner, but cannot reach a true carbon ring. BTW, not all barrels get carbon rings, and there is quite a bit of difference between powders' propensity to form one, so, lots of shooters may not have had the problem, which would account for the difference in answers.
 
im sorta in the line with longranger except i use a 14in. pc of easton1716 lite arrow shaft spread on end to fit chamber nk & take file & cut across end of shaft about 1/8th. deep to form cutters the alumumium shaft doesnt harm chamber but makes quick work of ring along with any good lube also leaving brass as long as possible cuts down on the build up in the first place thanks shooter63
 
I understand the elbow grease equation. my method I used prior was to wet things up with the GM TEC and then follow up with a brush twisting. That will get the ring formed at the end of the case. The other ring I get in a 243 factory barrel running H4350 is just past the throat. I used the solvent and brush as well as some flitz to help polish it out... I am always up for suggestions to help because the hard carbon past the throat is a PITA to get out! The chamber not so much. The barrel is getting worn 1000+ rounds and it never really had that much problem until 750-800 and it seems like its in 100 round intervals. I think its getting time to set back and try it again. Its getting worse. I would love to buy another barrel but with furloughs and a new baby times are tight. So I am up for anything at this point. Thanks again, Matt
 
Boyd, I never seen what you are talking about, except for the end of the chamber. The build up i get is not seen with the bore scope, only felt by pulling the rod back and feeling it stick like you use to get shooting 8208 powder in the PPC. A couple passes with a brush and followed by Iosso takes care of it. The down side is it takes a while to settle the barrel down to shoot small again. The end of the chamber carbon is handled by a 1816 x7 turned a .0005 under the neck diameter....... jim
 
Good tips on the end of the chamber, and the 8208, was that the surplus? Perhaps we all need to make some end of chamber tools. I wonder if a high polish of just the leade angle back to the neck would help cut down on hard carbon sticking? I can tell you, from bore scope observation that Flitz polishes a bore than I would ever want, rather quickly, but that might be a good thing right at the leade angle. What do you think?
 
Boyd, It was sold as fertilizer,T bird and 8208. I don't like using a brush in the throat moving against the path of the bullet so i cross that off my list. I use Warthog so maybe i don't see what you see. I don't like it squeaky clean, like with Iosso you just wear out the barrel till it settles down, i like just a light gray on the patch....... jim
 
Currently shooting 133 and don't have a problem. I agree with what has to be done after abrasive use. I try to avoid powders that require it. Lately, I have been cycling a soft nylon brush up and down the entire bore (20-30 times, slowly) with Patchout and Accelerator. Seems to work.
