Lengthen Forcing Cone
We suggest doing this work to every shotgun. For your money, this is the cheapest and best thing to do to receive better results in patterns and recoil reduction. 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. We lengthen the forcing cone to 3" and mirror polishing it. By Lengthening the 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 forcing cone and mirror polishing 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. Forcing Cone Lengthened............................$60
