I hate to say it, but I have honestly killed more golden gunners in their super form than they have killed me. I wish there was a way to show stats like that. Because I've honestly sniped a golden gunner before he could pull off a shot on me. They key is leading him. Heck, for any roaming super, the key is leading them. Have them chase you, turn a corner, then scope and wait for them to cross your sights and bam.
