Brownell's makes Chamber Brushes that I use for the Cylinders ONLY. They are slightly oversized and seem a bit stiffer than normal Bore Brushes. I use the Rifle sized brushes because of the extra bristles, longer length, and more scrubbing power per stroke. Since you go all the way through before reversing direction the extra length does not hinder anything and actually helps quite a bit. I but them buy the dozen because they do not last very long. Because they are a bit tighter I get only a few cleanings out of each one before they shed their bristles. Even though they are short lived, they make cleaning a real breeze.
A Lewis Lead Remover (Brownell's) is essential for any real revolver shooter. A few passes will quickly and safely remove anything a chamber brush won't and also keeps your barrel and forcing cones lead free.
