I gotta ask, how did people shoot accurately before the borescope was invented? Proper procedures, more specifically consistent procedures will produce predictable results. One does not need a bore scope to know their barrel is sufficiently cleaned. Now, “sufficiently” means a lot of different things to different people and that’s proven in the previous posts. I’m in the ignorance is bliss camp, I have family, a career, and other hobbies. I can’t sit at home like a tweeker and lose sleep over how clean my barrel is. If it shoots good, that is all I can ask. I stepped back from another forum because everyone had to measure their weiners, looks like this place is about the same.
