I use nylon brushes to introduce normal solvents into the bore. I stopped using bronze due to much of the 'blue' on patches, coming from the brushes themselves. If using a bronze brush, even a clean, non-fouled bore will show blue (copper) on a patch. To some extent, a bronze jag could as well (haven't seen that yet), but no where near the extent a brush gives.

Too - there is very little to no abrasive benefit from a bronze brush in removing copper fouling, perhaps in a minor sense with powder fouling. Since powder fouling is easily disolved and removed without brushing by using normal solvents, the brush's use is superflouous. This convinced me that bronze brushes were next to useless in helping me clean my rifles.

As to scrubbing any action, many rod strokes are needed and many rod strokes will end up being damamging to the bore themselves, due to rod flex - so I now use as few rod strokes as possible to produce a perfectly clean bore. The solvents I use today, do exactly this, without brushing the hell out of the bore.

I do not miss bronze brushes - at all.

Brush use is a long-time argument amongst the BR clan as well - each to his own.

Use them if you want, I only posted this to advise that they aren't needed. You can get your bores clean without them. I use square patches, pushed through from the breech, to fall off at the muzzle. They are not wrapped on a long jag and stroked back and forth - one way only and gone.
