IIRC, the full appellate court must review a panel ruling before a case can go to SCOTUS. Some of the cases on 2nd Amendment issues that have been followed closely here in the past have gone through this process.

I believe you are mistaken. Most cases are not reviewed en banc. The Ninth has made it almost required for Second Amendment case to go to en banc, it seems. But en banc used to be considered rare.
