I think the warden should thank you very much for being so diligent in spotting him in your field of fire and directing the shooter to avoid the area he was in. If he had his binocs at 250 yards and he had any kind of gun/woodcraft sense he knew damn good and well it wasn't a firearm. I'm going to say that at 250 yards with a pair of 7x35s I can almost tell the make and model of a rifle and certainly whether it is one or not. He sounds like a D**khead to me.
