I've recovered 4-5 168 TTSX, out of 3006 @ 2682 fps, from several mule deer and elk both close up (30 yards) to almost 300 yards. Lost petals etc. but killed the animals.
Internet experiences notwithstanding, I also had total failure of 4 different 120 TTSX out of 280 @ 3269 fps on bighorn (1 shot) and pronghorn (took 3 shots) in 2012. Total disintegration, little penetration, bits & pieces of bullet recovered on the pronghorn (of all animals), and lost the bighorn.
Have not shot one at an animal since.
Before the guru's take me to task, I routinely examine wound channels on animals I have shot, have a pretty good idea of how (numerous different) bullets have performed on my game shot over the last 50 years, and the TTSX failures were bona fide, not imagined or based on crappy shooting, excessive distances, iron plated animals, full moon, COVID, or Democrats.
