For me I started out using a peep on a Bow. Back then as an instructor I told guys to focus on where you wanted to hit and let the pin be slightly blury on the sight. I now do the same thing with my ML. I have a tiny lee shavers pin in there. So I can focus HARD on the spot I want to hit. Most gun instructors want the shooter to focus on the front sight. I can't . I have to focus on the animal and where I want that bullet to hit.
