Hello, first off what type of benelli do you have? Second I shoot Beretta shotguns and love them. I also like benellis. From my experience from my 12 gauge I would recommend the factory full choke given its not drastically off or somthing like that. I bought a turkey choke and it shot great at 35+ yards but after missing shots on 2 different groups of birds in one morning(one at 30 yards and one at 10)I changed back and havent given it another thought. I killed a turkey at 57 yards (miscalculation due to slope) and it was deader than a doornail. I personally wouldnt recomend shots over 40 yards. Given your full choke shoots well out of your gun at 30 yards. I would invest your money in a good call or possibly some true glow sights. If you call them in close and shoot straight you can kill them with a modifiedchoke (found that out by accident). But by far the biggest thing like they say practice makes perfect in everything that you do.
