I haven't shot anything with the Barnes X, but I loaded up some 130 gr. GMXs in the .270 WCF last year and saw the terminal effects on two whitetails. There was CONSIDERABLE bloodshot meat associated with both deer. Granted I thought the GMX was quite "soft" compared to the stories that I have heard about the TSX. Impact velocities should have been around 2880 FPS and 2250 FPS for the two deer and the wound cavity and blood-shot area was considerable in both.

I have attached two photos for reference. This was a small (70 lb.) whitetail that was my friend's first big game harvest. I loaned him the rifle and ammo. He shot it one time with the 130 gr. GMX (~3,000 FPS muzzle) as the deer was standing about 60 yards away. The first pic is the entrance and the second pic is the exit.

I agree with BrentD---there are too many variables to generalize about the performance of any given bullet.
