If ESR just stow the partial moon clip. For SSR I just dump the whole mess into my hand and into a pocket. For SSR, some shooters will open the cylinder and tilt the gun up to get the live rounds to fall into their hand and then eject the empties on the ground but I find that too time consuming. For stages like stage 3 in the classifier, revolvers get a pass on the RWR since they are empty you just do a regular reload.
