Thanks Larry. I recall in some past posts in threads where there was concern of reducing minimum wallthickness with a long cone. I was pointing out that it just doesn't occur with a lengthening of a forcing cone on most doubles, since that outside taper is so much longer than even my reamer for a 4" cone in a 12g.

Who'd have thunk this little subject would get a bunch of old men seeing red enough to insult each other? I'm sorry if I did that, myself, to anyone on this subject.
