The TSX line opens with hydraulic pressure. The tipped version uses the tip to initiate expansion. As velocity drops, expansion diminishes. With Barnes bullets, speed is your friend. Even at 2170 fps, this bullet will probably not "fully" open. I would likely run a lighter bullet at a higher velocity. You will get 100% weight retention and probably better terminal performance on game with a muzzle velocity nearer 3000 fps. Just my opinion. YMMV
The attachment is what the Barnes 225gr TSX will do at 2700fps from a 35 Whelen at around 60 yards; 235lb black bear; front, center mass shot exit behind the left shoulder. I've gotten the same performance with the 200gr TTSX from the .358 Winchester. I've been using Barnes TSX and TTSX for years with the same results.
