9 on the the skeet range is ok-make darn sure you wear eye protection those little BBs do come back at you a time or two. 8 and 7.5 shot are my go to loads. 6 shot at turkeys, 2s and BB for goose 4 or 3 shot for ducks.
Note you can brake birds on the 27 yard line using 9s, just not crushing breaks.
