This was posted back in 2005 as a way to remove a carbon ring. There were no comments at the time on it. Originally posted by member LongRanger. What do you think? Good way or not, is it possible to damage the barrel?
Verbatim
If you have or suspect carbon buildup in the small space between the mouth end of your case and the end of the chamber it can quickly be removed mechanically. Have used this trick for years.
Take a fired case and cut a series of small, pointed notches in the lip with a Dremel cut-off disk. Use the same cut-off disk to cut the neck off at the shoulder. Glue or force-fit the neck onto the end of an appropriately- sized wood dowel. Run your new cleaning tool into the chamber, by hand, until it stops. Give it a light twist or two. Remove tool and clean chamber. Carbon gone.
