A brush will certainly get some of it - if it is somewhat loose - but the worst part of it is usually blown and tucked in behind the lands on the breech side and normally closer to the breech than the muzzle. The biggest cause of plastic fouling is heat melting-working- on the cup of the sabot. Then if the sabot starts jumping lands again it leaves plastic as it jumps by the lands.

Most of the ML cleaners now have some sort plastic solvent in them, most centerfire cleaners do not unless you are using a shotgun wad cleaner, and if you do your routine maintenance maintenance with one of these plastic solvents you are probably staying on top of the problem. In the worst case - the solvent will loosen the plastic to the point the brush may be able to grab it.

I suggested the boiling treatment as it gets out all of the fouling including plastic in one easy step. The heat of the water will cause the barrel to expand causes the plastic to stretch loosen and release its hold on the metal and the flakes litterally fall out, with the action of a bore mop.

I am not sure that C Cleaner will get the plastic in one treatment esecially the really tough stuff, but again a lot of us are not really getting that build up - due to light loads and our own personal cleaning procedures.

I personally prefer not to use a bronze or brass bore brush, I will use a fiber brush on occasion but even then not very often or as it is needed.

Semi, How does this go along with your thoughts
