Years ago, I had a TSX pencil through shoulder blades on a buck. He ran about 100 yards, which caused me to quit Barnes. About ten years ago, someone encouraged me to give the TTSX a try.
They have been a very different story consistently providing effective terminal results. The TTSX opens very fast. The TTSX and LRX have become my go to bullets.
Here is a buck shot through the shoulder by my wife with a .308 Win and the 130 TTSX (45.5 gr Varget and a F210). This damage from the TTSX is not pencilling through.
