I never claimed that BB (Seasoned) My Barrel, and from preveious replays about BB I dont think anyone else has either. Th only thing I have claimed about BB is that it has (Protected) my barrel from rust, period. I have only used it as a protector against rust. A light coating after a cleaning, and a very light coating befor loading. It has always worked for me with no (build-up) as I never let it get to that point. I completely clean the barrel after a shot with hot water, then reload with a light coating.
