What is a shotgun's cone?

Just out of curiousity, I hear a lot of talk from custom gun smiths about adjusting or customizing the cone of a shot gun. What are they talking about? What is the cone and where is it?
Thanks
 
The forcing cone is the constriction at the end of the chamber that forces the load down from chamber size to the size of your shotgun bore.
 
What USP.40 said....Some people believe, others do not, that the lengthening of the forcing cone reduces felt recoil.
 
There is also some thought that the lengthening of the cone decreases the amount of shot deformation somewhat and improves patterns.
I have the forcing cone done of a few barrels and they do "seem" to shoot softer that those that have not been done.
FWIW, the new Remingtons that I've seen come from the factory with longer cones now.

Don't know of many gunsmiths that customize the cone-as in forcing cone--which is the shotgun choke. Of course, the choke could be reamed to open it up. Or the barrel could be threaded for choke tubes.

Are you sure you're not talking about the "comb", which is part of the stock dimension? Proper drop at heel and drop at comb adjusted for individual shooters, make the stock fit better, and the shotgun point as it should.

The comb is the top part of the stock where the cheek rests, and the heel is the top of the butt. The toe is the bottom edge of the butt. Drop with regards to these points on the stock are measured from a straight line drawn from the center of bore. :cool:
 
Nob,
The forcing cone is the rear section of the barrel just in front of the chamber where the shot charge enters the barrel proper, it is not the choke. The choke's up front at the end where the shot charge comes out, if there is any choke.
Lengthening the forcing cone gives the shot charge a slightly longer distance and angle before it's compressed into the bore diameter, and many people (including me) believe it helps a bit in perceived recoil.
Hans Vang, and others, make a fair amount of money in lengthening those forcing cones.
