J-B Non-Embedding Bore Cleaning Compound by Brownells

had heavy lead fouling in my bore, a caked on layer, that took a lot of work to remove, used kroil, hoppes 9 and brass brushes with rods attached to my hand drill, after 15 minutes of this the bore was finally clean (at least to my eyes) then I rubbed JB on a patch , wrapped the patch around a nylon bristle brush and into my drill, made a few passes and couldn't believe how much more lead came out after I thought it was clean. I know this isn't the "micro polishing" model but it still seamed to polish my chrome bore. essentially alll those hairline scratches are gone and the inside of my Benelli M4 bore looks like a brand new chrome car rim lol.

The product works as advertized, that says it all.

Très bon produit.

Have read about this stuff for years. The rumors are true, cleans consistently and is repeatable. Takes about 5-7 pews to get back to normal after cleaning. Read about it in AB vol.III. Follow Brian’s instructions. My old cleaning process used a different way to clean the barrel. It worked just fine, but took 5-25 pews before it returned to normal. After using both process, they foul at about the same rate, 200ish, with my pews(not spicy). Much happier with this stuff.
