I am trying to learn all I can about the different forms of ignition used on muzzleloading firearms, including side hammer, or mule ear guns. I have read two statements about mule ear guns that make me wonder... One is that some mule ear locks have no half **** position, and the second is that some mule ear locks have a quarter **** position. My questions are, why a quarter position? In place of a half **** position because a half **** position would cause the hammer to stick out too far? Or did a mule ear need a quarter position and a half plus obviously a full **** position? Thanks.
