I don't think anyone is claiming to be a pro. The author wants something that is super accurate at super long ranges with super energy. I don't think there is anything that fits that bill that is fur friendly.
I understand where you are coming from on the being able to see them coming for a 1/2 mile, thats what the majority of my locations allow. I've had a few hold up at 200-300-400 yards, and my Tikka 243 or my AR 15 always reaches 'em.
