When I sight my rifles in, I want the best group possible. Also because of the environment I hunt, I often sight in for a much closer distance then say Sabotloader or some of the people that hunt large open fields. That is only understandable. I also know my White Rifle always throws the first shot on a clean barrel which is why I hunt on a fowled barrel. I'm not taking chances when I only have that one shot. But I also know that when the rifle is fowled and loaded properly I can place my shots which extreme accuracy. This group on a dirty barrel I consider very acceptable at 70 yards.
