I just realized why Chris shot Dino Zerilli two more times when he was already dead. Until now I'd thought that it was just done to look "cool", which struck me as odd because The Sopranos never goes out of its way just to look cool. It makes sense now - this was one episode after the incident with the Russian, who got back up and kept running after Paulie plugged him in the head. So Chris isn't taking any chances with that shit anymore, he's making sure the dead stay dead.
