100% fool proof way to not have a carbon ring form.... dont shoot it. Just kidding I try and stay ahead by cleaning often and have been using the Boretech products and Some JB when needed. BTW mostly shoot SR benchrest with some varmit hunting threw in, so a clean barrel is a must for me. I purchased a Teslong bore scope and really like being able to tell how the cleaning regimen is working or not working...
