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.
