Also, i found that the gap between the forcing cone and cylinder ,seems to be crooked, in that the top of the forcing cone is dragging lightly against the top of the cylinder, while there is a gap between the bottom of the forcing cone and bottom of the cylinder.So the barrel gap is not even
Checking last night , it seems that the forcing cone itself was not ground flat, as the top of the forcing cone is dragging against the top of the cylinder face, while not touching on the bottom
Checking the face of the forcing cone last night with the barrel off.It seem like at the factory they laid the barrel flat and hit the foxing cone against a flat face grinder of belt sander …but moved…causing a (Slanted ) cone face
I rotated the cylinder last night,and found the gap to be the same all the way around as I rotated the cylinder.So i believe that it is simply the forcing cone
Man, I feel so far that Iver Johnson did a better job of my (F Series ) Dragoon
