I just took my recently acquired 1901 Vulcan 12 gauge. As I was getting ready a friend came by, looked down the breech and said, "Someone took the forcing cones out."

A bit of reading told me that many guns of this era did not have cones but shoulders as mine does. Some said that using modern ammo without a forcing cone would loosen the hinge pin. Others said adding a foxing cone could create excessive pressure.

Does anyone have any info or suggestions about the desirability of forcing cones in a 114 year old gun?
