Hello all. New member and new Benelli owner. I just got my Super Nova a few days ago. I've cleaned it twice now but want to see if I missed anything. First of all, after the first cleaning I took it out for a trial run and the shotgun smelled something awful after I finished up shooting. Is that the cosmolene causing that, or something else? Beyond that, I have never owned a shotgun before. What are some tips for cleaning it? Do I lube the pump on this thing? Anything you have, I'll listen! I want to make sure this thing is going for a long time because it was love at first shot and I am hoping to take it out hunting.
