I have a couple knight rifles with fiber front sight and rear peep sight. At 100 yards and less I aim behind a buck's shoulder, with the top of the pin at the shoulder. At further than 150 yards, I think it would be difficult to see behind a buck's shoulder? Right? So, is it logical to aim with the top of the pin at either the top of the back or his belly so the impact is behind his shoulders? This could only be done with an field adjustable rear peep sight that could be dialed for elevation on the fly? Thanks Bill
