I don't, but have an opinion for what it's worth, based on using TSX in other calibers.
First, I consider the TSX a wonderful bullet for larger game from deer on up. It penetrates into tomorrow, but exits are sometimes tricky. Sometimes it's a tiny hole in and a tiny hole out. Other times the exit is larger and a few times, depending on where the animal is hit, has a large exit. So, the bullet is not always consistent with exit wounds, but it will certainly penetrate.
Next is price. It's definitely not cheap to shoot TSX compared to other bullets, and there's a lot of good conventional bullets that will work very well and be much cheaper.
I have found the TSX to be a very accurate bullet, something that is fairly unusual for a controlled expansion bullet.
Sorry I can't tell you "yes" that I have used it on predators, but I do have quite a bit of experience with the bullet in larger calibers on deer and antelope.
