This is not a problem with chambers. Ammunition dimensions vary from one maker to the next, so it is certain that one type will allow the cylinder to rotate and others will not allow it. Measurements mean something. You are looking for .006 - .008" headspace on a revolver of this caliber, measured between an empty case and the recoil shield (measure with feeler gauges). As I said, it is a serious problem and not a matter of cleaning or polishing. So, what is the headspace measurement?
