The TTSX was recovered from water and the Hornady from a longer range soil backstop, have never recovered a TTSX from game. The Hornady showed jacket - core separation. Initially I thought it had mushroomed brilliantly but then I dropped it on the floor and the tiny remaining lead core came out. The 162 SST currently holds my personal record for being the most meat damaging bullet I have experienced. However it is effective at longer ranges.
I don’t often take neck shots to be honest, I invariably either chest or head shoot where appropriate conditions exist. I have had no problems with the TTSX bullets pencilling through the head. The results have always been dramatic with generally both eyeballs prolapsing, there being a mist of escaping fluid around the head that is visible through the scope and the bullet continuing in a straight line, often through the first two cervical vertebrae.I am happy with how they perform in this application
