When there is sufficient roughness to provide enough friction for a certain level of resistance to extraction, the extractor's claw slips off the rim and the fired round stays in place. The polishing by the crocus cloth approach removes the microscopic high spots inherent in the roughness which have been holding the case in. A smooth chamber will allow the very slight taper of the case to move with very little force required, since with smooth walls, there is little or nothing locking or grabbing the shell's outer walls. Go easy, as the other guys mention...a few spins of the polisher setup...give 'er a try... another few spins if necessary...etc. Also check visually as you go. A final tip, slip the setup into the chamber, then do the spins. Keep the 1/2" strip of crocus cloth moving in and out smoothly to help make the polishing even, and avoid rounding the back rim of the breech by not pulling the setup back too far.
