I don't think there is a wrong answer here. Go with your gut. Either one is going to give you the results you are looking for at the distances you posted. No matter what you are shooting shot placement key.
I have had great results with the 123gr sst in the 6.5 Grendel on hogs.
Just used one of those a month ago on a pig at the house. I was kind of amazed she made it almost 150 yards. Further than most that I shoot with 223. Goes to show you never know. She was dead. And easy to find.
