Abstract: An apparatus and method for firing a projectile in which one part of the projectile rotates and the other part of the projectile does not rotate where is it used for delivering a line. The projectile firing apparatus includes a projectile having a part that rotates and a part that does not rotate, and further a barrel with a bore having spiraled grooves and at least two channels for the nonrotating part of the projectile to travel through when the projectile is fired. A line dragging system is mounted on the front of the barrel and engages to the nonrotating part of the projectile. The line dragging system is made of a wire frame including a cylindrical portion, engaging members, frame sides, and engaging locks. Upon firing the projectile, the rotating part moves through the bore of the barrel while the nonrotating part moves through the channels of the barrel.
