It seems to take much more than a single fouling shot with this barrel, more like 30 to 40 rounds after being cleaned down to bare steel.

I’ve only found two products that clean to bare steel, JB bore paste and Bore Tech C4. C4 takes everything out except for the fairly thin layer of hard carbon in the throat. JB takes it all out. This barrel has pretty bad pitting in the middle 1/3 of the bore and that’s the area where I think some fouling helps, but it needs to build up and get ironed smooth by successive bullets going down the bore. At least, that’s what I think is going on based on borescope observation and grouping results.
