I have a Bergara Premier 6.5 PRC Its a 1/2MOA capable rifle if I do my part . I usually use wipe out or Sweets 7.62 for copper removal Butches bore shine for carbon, Cleaned bbl up using Butches and Sweets,looked down the bore a few times thought it looked sweet. Then I ran a bore scope that I wi fi into my I phone .BBL was loaded with copper and carbon . Now it's gonna soak overnight in wipe out and its accelerator. Who out there use a Bore scope and have you changed your BBL cleaning methods ?
