Looks like the 40 yard pattern isn't centered. Should be moved left unless you pulled the shot. Have you shot a dove load at 12 to 15 yards to get POA/POI. My 835 shot 3" low and 3" right so I put a red dot on it to correct that. With the Stardot (great choke for the 835) and 3 inch #9's that 40 yard pattern should be tighter. I would suggest deep cleaning and polishing the barrel as well as checking POA/POI. Will those patterns kill with TSS absolutely but they could be better. My 2 cents.
