Benelli is the only auto to use in the high volume shooting. They just keep working. I shot a 28 gauge Beretta BL 5. The only issue I encountered was a little charred wood where the bottom barrel abutted the fore end.
If you are going to to shoot an auto take some adhesive tape to put on (over your shooting glove) on the thumb of the hand you load with. it will save you some skin.
