My daughter took muley in the Montana youth hunt this past Friday. 120gr GMX out of a 6.5 Creed going 2750fps. The deer was facing us at a slight angle 35 yards away at the shot. Bullet entered just in front of the near side leg and just below the spine. Destroyed one lung and continued on the length of the animal exiting the ham, but not hitting any bone besides the ribs at the entrance. Deer dropped in its tracks at the shot but managed to regain its feet and stagger 20 feet or so before it gave up the ghost. Entrance and exit holes where small and there was no blood leaking from the wounds.
Seems to perform identical to the Barnes TTSX.
