I've tried a lot of different chemicals over the years to get rid of carbon deposits in barrels with out much success. After using said chemical, I would use brake cleaner to clean out the bore. **** thing is, when the patches came out clean after using whatever, in this case "C4 Carbon Remover", running patches soaked in brake cleaner afterwards would have black streaks, when the C4 showed nothing!
My Riflesmith for years has suggested carbon needs 200-300 strokes with bronze brushes using a carbon remover, Kroil, something so the brush is not dry, to loosen and break up the deposits to get rid of it. Nothing is going to "dissolve" a ceramic like slick.
This weekend with my bore scope, I could see a carbon ring, along with carbon in the lands for a few inches, which I suspected was giving me erratic pressure problems while doing load development this past week on a particular rifle.
I've done this several times and hate the process. A squirt down the bore through the bore guide and soak the bronze brush with C4 carbon remover, for 15-20 strokes and then patch, had just a hint of carbon residue on a patch after brushing.
So in the last week, I've done this to three barrels that had excessive carbon deposits. Did them using brake cleaner with "several" bronze brushes. Saw Immediate results using the brake cleaner. Running a patch through after brushing came out completely black. It took about an hour of brushing, but eventually the patches came out clean and the bore is bright/shiny and squeaky clean.
At first, I thought this was too good to be true, and maybe there was a chemical reaction with the bronze brush, brake cleaner and stainless steel causing the black residue and nothing to do with carbon removal.
Anyway, I thought I'd pass this on.
Cheers, Gary
