Stoer M3020 turkey federal 3" 1 1/2 oz #9 Tss  Indian creek .555

  30 yards I counted 346 in a ten" paper plate. I like it I just though im missing 200 pellets

Very good, but you might find the .562 or .570 patterns even better.  Guns and barrel lengths are different, but most tss loads have led me to open it up more for excellent, even patterns.

I was wondering the same thing.  you saying the pattern will tighten but more even possibly?
  I not dissatisfied but i do think my 870 which has a 21" barrel same choke is a little tighter.
  All that said Im sure this will do the job

You're pattern looks good and not "blown out" which sometimes you might see with a tighter constriction on some loads.  I like to see it on a larger paper, but yours looks good from what you can see there.  With what I'm referring to sometimes opening it up more produces a more even pattern from the center on throughout.  So while you aren't shooting "tighter" you could see better results.  Like I said, your numbers look great though.

Ok thanks for the help.  I should have showed it on the large piece of Luanne i had it taped to but really it was just a few on the outside fairly even all the way around.  It was about a 16" diameter at the most

If you follow Hal's rule of thumb, you will be around 250 at 40 yards with that pattern.
