Mossberg 835 with Redhead Blackmaxx and Federal TSS #9 @ 40 yds

[Mossyballs]

Should I be happy with this 40 Yard pattern considering the shot count in 3" #9 TSS?

Its hard to tell on that small target.  You need to shoot a large piece of paper, your pattern looks a little low.  I can tell you with those shells and an 835 you shouldnt have any issues.
