The hydrostatic shock of the TTSX bullet will greatly surpass a bullet that fragments inside the animal. That hydrostatic shock will destroy tissue and organs more "thoroughly" than little copper fragments. Check out the first pics posted in this thread.... a TTSX bullet that stayed inside the animal and was recovered.....from a .338 There's a million ballistics gel videos on youtube that confirm that the wound channel created by the TTSX / TSX bullets is nasty compared to jacketed ammo. But, to each their own.
Can't agree more. The X bullet is also nuts accurate. They are designed to create hydrostatic shock which is reliant on hydraulics not fragmentation to produce shock and trauma. This whole thing of expending the entire bullet into the animal versus the inferiority of a pass through shot is just unfounded.
Like BWE said - to each his or her own. Whatever works for you...
