I was just wondering how often you guys clean your auto shotgun after shooting? I mean I always run a patch with 'Hoppe's solvent through the barrel and then lightly oil. I mean how often do you actually field strip it to clean it? I just purchased a Mossberg 930 Tactical and the owners manual states you should clean it after every 200 rounds. I am assuming they mean field stripping it. I don't think I would go 200 rounds before field stripping and cleaning it since it is used for defense purposes. It needs to be 100% reliable and I think it should be cleaned before 200 rounds. What do you guys think?
