LawrenceHanson said:As I understand it, the Bore Tech line of solvents are water-based surfactants. I have tried all of them and continue to use Eliminator only. The CU+2 copper solvent was no more effective than Eliminator and C4 carbon cleaner turned out to be snake oil, just like any other carbon solvent I have tried. Cleaning the barrel of an AK-47 that has had thousands of rounds of dirty east European corrosive ammunition fired through it has shown me a thing or two about the effectiveness of various bore cleaners.

+1 on the tool used in your photo!
Only way to know if carbon is removed. (not powder fouling, not copper fouling but CARBON fouling). Carbon can and will be polished to a mirror finish by the time people think the barrel is clean. This means the white paper mirror test isn't really a perfect example. Bore scope is the only way to know for sure.
I'll go on to add: Does your accuracy suffer from Carbon buildup? Its for you to decide. Old ways of cleaning and old processes still work for most, so keep up the good work I'm not saying you need to change.
