i dont know sounds more like bird hunting than deer hunting to me.I never heard of anyone saying to lead a deer sounds like a good way to miss,wound or send a slug flying where it could hit anyone or anything.
Now therefore take, I pray thee, thy weapons, thy quiver and thy bow, and go out to the field, and take me some venison.
Genesis 27:3 "The thinking deer hunter should mature through three phases during his hunting life. First phase, "I need to kill a deer." Second phase, I want to harvest a nice deer. And last phase, we must manage this resource so our children and their children can experience the grand tradition of good deer hunting." - Jim Slinsky
