Well, I went to the gun shop and decided to try RB-17. I can't believe how well this stuff works! My dad has a Ruger Mini-14 that he rarely cleaned. There was a huge build-up of copper in the bore. I have used Hoppe's #9, Tetra Copper Solvent, MPro7, J-B paste, and half of my patches trying to remove the copper. It still didn't come out. Amazingly, with just one application all copper was removed! I couldn't believe it! Well, out of my findings, MPro7 is the best at removing built-up powder and carbon, and, when used with a scouring pad, is very good a lead removal. RB-17 is unmatched for copper removal. I have not tried RB-17 on lead yet, so I can't tell you guys how good it is at that. Joe
