I have a Supernova that jams every so often. Like, it jams so hard you have to remove the trigger assembly to free it up. I'm hardly a prolific poster on here, but over the years a fellow poster has had some very good info about Remingtons (I think he's called The Virginian) and even further back I recall some excellent advice from a poster regarding a Mossberg 500. So, who knows, maybe there is a Benelli guy here too! I hesitate a little to link this here, but there is a guy on YouTube complaining about his Nova, and the issue seems almost exactly like mine. Most of the responses say he's short shucking, and I'm probably 65% in agreement with them, but not completely sure. The link to the video I'll put below, he is cursing a bit so if you don't like that kind of thing please don't watch. He seems a bit odd to me but hey, it takes all sorts. The jam occurs at about 1 minute 15 to 1 minute 30.
