I bow hunt too, but beyond 50 yards is pushing it. I have more respect for the animal, and have to be truly sure of my shot than to loose an arrow beyond that. I felt very sick when I hit a woodchuck back east when I was a teen, and have it run into a hole to die. I take lead from the military snipers, one shot- one kill. As for 800 yard rifle shots, I would never attempt it, no matter what the conditions. If you miss your aim point, break a leg, belly shot, what do you do for a follow up shot. I passed up many a whitetail because the setup was not right. I know you guys practice probably far more than I do, but there is that little branch you don't see, or that unexpected gust of wind.
