I have been invited to hunt on some private property in Jan. It is almost guaranteed that there will be does seen of which I personally don't care to shoot. However I woudn't mind my son shooting one for a little freezer meat. He will be 7 is about 3 1/2 ft tall and weighs about 45 pounds. He is deadly accurate with a .22 out to 35 yards. He will be closely supervised and shot placement will be a high priority. So I guess what I'm gettin at is will the .243 be an effective deer rifle out to say 50 yards?
