For the record, I am not taking 1k shots at animals because I am not prepared yet; although I have whacked rocks and gongs at that distance. Right now, 800 is my max range. I've recently taken a whitetail buck at 754, a doe antelope at 785, and a cow elk at 760. All one shots kills.
Maybe I think bowhunting is unethical? Or I could think that because my ability with a bow is non-existant? If I hunted with a bow I would probably be one of those guys who went home to let the deer lay in the woods overnight with an arrow sticking half way in the guts. But, I don't hunt with a bow and never will... because I have no skill or interest with them. When that big buck pops out across the canyon at 600 yards, there's no doubt that he's getting both front shoulders broken by a 180 grain Triple Shock.
