[QUOTE="Rardoin, post: 2033482, member: 114954"] A carbon ring will build up in the chamber neck area in the space between the end of the case and the transition to the freebore. This ring is only of consequence when it gets thick and hard enough to impinge on the end of the case and possibly contact the bullet (if really bad) and cause pressure spikes. The more insidious carbon ring is a very thin layer of hard carbon built up in the freebore that will cause big pressure spikes and hard bolt closure/ bullets sticking in the freebore on extraction if neck tension is low enough. I use a bronze brush slightly larger than the chamber neck diameter on a chamber brush to clean the former. I use a caliber diameter bronze brush on the same chamber rod in a short stroke pattern to eliminate the latter. I also use a bronze brush to clean the entire bore as my first step in carbon removal using a specific carbon cleaner. I use proper bore guides and high quality bearing handled rods. My barrels are not damaged by the bronze brushes when used in this matter. I also pull the brush back through the muzzle each stroke (OH....THE HUMANITY!!!....LOL). My crowns are not damaged either. Don’t fear a regularly and properly used bronze brush; carbon removal will become a non-issue. [/QUOTE]
