Someone more knowledgeable may come and correct me....but I believe that the 7 shot number is for 2.5 and 3 only. 3.5 is going to lower the number of round s that your shotty will hold. This is, at least, my experience with the shotguns that I have....and I admit that I do not own a benneli. Have you tried feeding the different sizes to see how many will go? That would be a quick way to find out.
