Every br shooter i know uses iosso, flitz or jb extensively thruout the life of the barrel. Butches, bronze brushes, and abrasives when needed- usually after a 2 match day (10 5shot targets)
According to the BoreTec Chemical Guide on their website the Eliminator is rated as Good for carbon and their C4 is rated as Excellent for carbon. Both their Eliminator and CU+2 are rated as Excellent for copper. This is why I use the two step C4 and CU+2 for my regular cleaning instead of the one step Eliminator but I do use the Eliminator when I want to do a quick cleaning like at the range.I use Bore Tech Eliminator as my cleaner, it is supposed to take care of carbon and copper.
