G96 and Butch's Bore Shine?
Yesterday, I tried both Hoppes 9 and Break Free, which is what I had at home, but have G96 Gun treatment and Butch's Bore Shine also- that I did not try.
I got gun squeaky clean but rings are still there.
Nobody mentioned G96 and Butch's Bore Shine so far, so I am assuming that those two are not good for this job either?
Friend at the club mentioned Flitz, I will bring it along next time and try spraying it down cylinder while still hot, might help clean up efforts later.
