I have a Super Nova, about a year and a half old. I too have a problem with the barrel rusting. I have to take a rag with oil on it and wipe the barrel when duck hunting. I also have a problem with mis firing. I have tried everything mentioned on this site, but nothing works, it still fires when it wants to. Now, I have a friend who has a Super Nova thats about 5 years old and no problems at all. Something was changed in the last 2 years and the quality went in the toilet for the Super Nova, and I see complaints about the Stroger 2000 firing when it wants. But Benelli hasnt said a thing about the problem, or that they will look into it.
