I keep em in close.In the thick black brush i can hear deer walking arround me all day somedays,but you cant shoot them if you cant see them.By the time i do see them,sometimes there in my back pocket.I wouldnt feel comfortable shooting a deer in the head more than 30-40ft.without a scope,and i dont like scopes in my neck o the woods when the farthest shot will be 50yds.
