This is the method I have been using for years with great success. It has saved me countless hours of scrubbing.
I use a rifle brush of at least .020 over barrel bore diameter chucked up in a cordless drill. Example a .375 rifle brush for a 38/357 cylinder.
Just apply your favorite solvent to the brush and spin the brush backwards into each chamber. ( it keeps the brush from un-screwing from the threaded shank, at least on Pro-shot brushes) Make sure to run the brush completely through but be careful not to let the drill chuck touch the cylinder. In one, or at worst, two passes the cylinder is spotless.
Then clean out the chambers and you are done with the cylinder.
This method also tends to very gently polish the inside surface of the chambers. I have been doing it for years and have not enlarged a single chamber. Of course ONLY use bronze brushes.
I hope this saves someone some time and sells many rifle brushes.
