The rws 8.3 superdome is becoming my favorite rat pellets. 3 for 3 tonight between 15-30 yards. I shoot at them out of the up stairs window at night alot. Im using an s500 with the power dialed to 850 fps with the superdomes. Its about as slow as I can get them and its perfect. Got that last one right in the neck peekin over the rocks it was such an awesome shot lol. I dont know why but I get more excited shooting rats than hunting big game!
