Hi! This may be a silly question, but since i havent tried yet, why not ask you? I have a Benelli Nova(amongst others) with a two round tube extension, making it a 7 shells-gun. Im wondering what kind of ammunition i can use to have 7 shells in it? The gun can fire 3,5" shells, but is there room for 7 of these? How many 2,5" can i put in it?
