Patterned the new federal heavyweight tss #9 in my 870 youth with several chokes.
Results at 40 yds:
Indian creek .555 ------------------(292-10)
Tight wad ------------------------------(274-10)
Trulock fed 7 choke --------------(208-10)
Carlson .555 -------------------------(185-10)
Rem super full (lead) ------------(175-10)
Jellyhead maximum ------------- (30-10)
I have no clue what happened with all the shot with the jellyhead choke. I shot a piece of cardboard that was 3'x4'. And the shot was so sparse. No concentration at all. However the Indian creek and tight wad did really well. The tight wad was a more even pattern but the Indian creek had a tighter core so i went with that choke. I didn't get to try my Carlson long beard choke as i was down to ten shells left after pattern testing and sighting in.
