IMO you're fine. The TSS # 9 shot has the power without question. And your load I'm sure is just fine. I also reload my own TSS using 9 shot. Here's a pattern I shot with my Encore 12ga at 60 yards. They say 100 pellets in a 10 inch circle is a dead bird.
170 should work
. Not that I intend on killing one that far. I just wanted to know.
Here's my beneill supernova at 30 yards same load.
The shot holes with black sharpie marks are from my 20 ga I just hated to waste a target lol. But as you can see if your gun patterns the shot/shells good and you put the pattern on the head and neck. There history.
If you hunt long enough things happen and it will happen again sad but true. You just deal with it do your best and just accept it's part of hunting.
Best of luck this spring
