I've been thinking that used, with care, brake cleaner should be a great way to clean your bore. I'm gonna try it...
Yes, it works very well. With care, its use is an effective barrel cleaner. But with careful use. I spray my barrel from the back to the front with a little straw. Pointing the barrel downwards so as to not get any in the action or in contact with anything other than the inside of the barrel. (And, in a well ventilated place or outdoors.)
After it's dry, I swab the barrel with CLP and patch it until the patches come out clean and dry.
