The friend I hunt with in ND has a Benelli SBE he bought new the year they came out. Over time, that thing looks like it fell in the swamp for a couple years and then recovered. I tried to clean it once years ago, but needed a vise-grip to turn the magazine cap due to severe rusting. I'm sure there has never been a patch or brush run down that barrel. Although he complains of occasional misfires (what a shock) he still uses it, and is one of the best shots I've seen in the field.
