Any good bullet ought turn the heart and or lungs to soup. If penetration is a concern, the TTSX is the answer. A Barnes may not leave a great blood trail, but it sounds like most bullets do not due to their hide. The Barnes will penetrate though! A 160gr moving real fast if you want to turn the inside to soup, or a 185 if you want to trade a little damage (maybe) for more penetration. If your shots are not too far, the TTSX will open really wide and you'll be surprised at the internal damage. The only TTSX I've recovered was a 160gr that penetrated ribs on both sides of a waterbuck and was caught in the thick far side hide. Internals were a complete mess.

If it were me, I'd load 160s to 3050+ and go hunt with zero doubts the bullets is going to do its job.
