I've got one of the older models with the Invector choke system. I've had the best luck with 3" Winchesters, either 2 oz. #4's or 1 3/4 oz. H. V. #6's. Mine will not shoot #5's consistantly, either regular or H.V.??. For several years I shot it with the factory x-full extended turkey choke. 4 years ago I got an Undertaker tube and had the forcing cone lengthened. My groups improved about 30%. I can consistently get 30+ hits in the head and neck with #6's and about 25 hits with #4's at 40 yds.
I shoot the factory full strut tube and Rem. 3" #5s. Ive had great patterns with this out to fifty yards but i keep my shot below 40 for insurance. I have the BPS with the Inv. + chokes and a 26" barrel. Owned it almost 2 years now without a single complaint. Enjoy

I don't know what they shoot the best but I have been to 2 banquets so far this spring and spent a pile of money trying to win that gun, man that is one sweet looking Browning. Congrats on your win.
