[QUOTE="Rhovee, post: 1767470, member: 101820"] A carbon ring is when that residue builds up enough that it touches the bullet. Small amounts of carbon deposits in front of the mouth of the brass isn’t necessary a carbon ring. A carbon ring is where the build up is so sever it’s touching the bullet on chambering. We’re talking excess of .012-.014. When I clean, I first soak a patch and spin it in that area to get it soaked. Follow normal cleaning. Then at the end I take a oversized bronze brush and spin it in neck/throat area. Follow with some patches and have never had a problem with carbon ring. I do clean it every 50 rounds and check lands. Nylon brush with some JB paste also works well. Just make sure you clean it out. Some brake cleaner on a large patch spun in that area will help. I use brake cleaner with a bronze brush with patch over it for cleaning chamber as well. Carb cleaner works as well. But leaves a small oil film for rust prevention. You must then clean it out with Alcohol on a patch. [/QUOTE]
