I shot 5 or 6 deer a few years back with sst's. I never had a problem with them . I had great results unlike some of the stories I've read. I wouldn't hesitate to use it if it is accurate in your gun. The Barnes you mentioned is one of my favorite bullets. Definitely can't go wrong with it for sure and you might want to give the 250 gr Bloodlines a try . I been having good results with them last year and this year.
