You're missing the point.
I believe you are the one missing the point. You started this whole thing stating one set of parameters then altered it bit by bit as it progressed. You put down others because they are not in agreement with your own set of hunting tactics/ethics. Every hunt in which an animal is ultimately taken eventually comes down to a test of marksmanship whether with a bow, rifle or handgun. This regardless of whether the shot is from 15 yds. or 315 yds. If you don't think you will like all of the possible answers, don't ask the question.
