Recently purchased a Benelli Vinci and fired it for the first 100 rounds, definitely an awesome shotgun! Never had a shotgun with removable chokes or made from composite materials. Could anyone give me some advice on the following questions? 1. Should I remove the choke tube when cleaning the barrel? 2. Should I use any particular oil or lubricant to clean the shotgun (Benelli recommends their own cleaning kit and oil, however are there any alternatives if that is not available?) 3. Are brushes recommended to clean the shotgun? (which parts?) 4. Is there a special cleaning solution/oil for the choke tubes? 5. Or should I just scratch the aforementioned questions, and just clean it like any other shotgun? Thanks!
