I have a new Benelli Super Black Eagle II that I loved til it started jamming.  I have disassembled it and lubed it but still it fails to completely eject.  Sometime it will barely get hung up and others you got to really struggle with it to get it to eject.  I have told all my friends how great they are and they are still saving to get one.  Now I need to get this under control or tell them they are a POS. Also, I shot a turkey today and it fell down and went to thrashing around and the gun jammed and the big finally go up and left with me standing there looking puzzled. Also, had a premo duck hunt last year and it jammed at the worst minute.  Also, went on a goose hunt and it jammed but I thought it was do to the mud or something. What to do?

Take barrel off. Clean then gas ports in the barrel. I think they have gas ports. They should be inside where the ring on the barrel goes over the mag tube.

Unless Benelli has redesigned their semi-action shotguns, the SBE II operates by inertia/recoil.  It should be the same system as the original SBE.  These shotguns don't have a gas system, which contributes to their trademark reliability.
