I've seen kill patterns at 100yds and heard of several kills further.
Can you give some detail to this?
It wasn't TSS but I've killed a coyote over 100 yards with discontinued Federak HW15-BB. By far my longest shotgun poke. I was in a hurry and misjudged the range. The gun patterns well at 85 yards on paper.

Note Spuriosity's follow up post regarding ballistics in that thread.
"I misspoke on the drop for HW15 BB @ 110 yds
. It is 30", not 36" (misread as HS instead of HW15) with 3.97"
penetration (1300 fps).
Lead 3Buck is almost identical with 29.43" of drop and 4.1" penetration (1300 fps)."
