Best carbon ring solvent??

Donovan, I have a thing about the carbon and the big gap between the end of the case and the end of the chamber. I believe it is picked up and carried down the barrel. i keep mine clean and i don't see anything in the barrel,ever. I also believe this is the rundown carbon with the next round. Spinning a bronze brush in the throat area just irritates the situation....i maybe over thinking the situation but the use of Warthog 1134 sure does help and i don't have these problems....... jim

I have not seen a lot of them myself, what I have seen were right where the chamfer at the end of the neck part of the chamber transitions to the freebore, not down in the corner which is really just hard to reach powder fouling, and not that hard to remove. What we are dealing with is the difficulty of "showing" someone what we mean. On the carbon ring, a friend has had the problem with a ball powder, and lots of rounds (prairie dog hunt) before cleaning. A switch to another powder, extruded, and the problem did not reoccur. I am not surprised that many have not seen this, but my friend actually was seeing his length to touch get shorter, until he removed the problem, with IOSSO. I shot a lot of 748 in a tight necked .222 and have never seen this problem, of course I did not go as many rounds between cleanings, and may not have been loading as hot as he does.

Boyd, I try to clean every relay with 10 shot strings but if i get pressed for time in the light i will go two. About 4 wet patches of Warthog and dry one and a 50/50 mix of Hoppies and Kroil and a 11/8 patch dry and clean it's nose and the chamber and she's ready to roll..... jim

After obtaining a bore scope and retiring and nothing to do. I spent a week cleaning over 50 rifles.

Boyd is correct as far as I am concerned. I could never dissolve a true carbon ring with various solvents and paste. The ring must be pulverized and then be removed. The only thing I found to work for me is to let the ring soak over night with a Kroil patch in the throat area. After an over night penetrating soaking the elbow work starts by twisting an oversize bronze brush in the throat to pulverize the ring to remove ring in pieces.

Then I can clean the carbon fouling with JB or IOSSO patching as required.

The carbon starts with the first firing and depending on your cleaning technique and solvent, it will continue to a ring which ultimately can and will form a ring in the end of the case neck area and throat ( one could have two rings of carbon ) area depending on powder type used current barrel wear.

Just my .02¢ worth.

I don't have a borescope, but right now I'm using Stihl De-Carbonizer and a brush. Cheap and it seems to work.
