The area in a shotgun barrel just in front of the chamber that directs the shot load into the bore is called the forcing cone. In most production shotguns this forcing cone is very short and at a steep angle. Ballistic Specialties lengthens the forcing cone to 3" and mirror polishes it. By Lengthening the forcing cone and mirror polishing the surface several good things happen. Velocity is increased by reducing the sudden friction encountered with a short forcing cone. Felt recoil is reduced because the reduced friction allows the shot load to smoothly enter the shotgun bore. Pellet deformation is dramatically reduced because the shock of suddenly constricting the shot load is eliminated. As pellet deformation is reduced a more dense and even pattern is produced.
