I have a 835 and I mounted a Simmons 2X scope on it. Love the scope. I use a Hastings .685 choke and have great patterns using 3.5" Winchester HV 4's and 3.5" Remington HV Hevi-shot #5's. If you have no trouble dropping a longbeard at 40 yards with your setup---not sure you need to change anything---but if you are like me---I like to fool around each year in search of the dream pattern. I'm am also not sure the dream pattern is a soft ball size pattern at 40 yards since I would also like to have a little room for error for closer in shots.
