Jordan, there are several studies that correlate the same as the one I posted.
In regards to your mention of the wound channel dynamics of a TTSX vs a lead a copper bullet. The intial part of the wound channel is where much of the damage is done. As the bullet slows cavitation drops off. So even though a ttsx might dig a few inches deeper it isn't doing much damage. And this is a big maybe as certain lead and copper bullets penetrate in a similar manner.
I would also mention that the link I posted above clearly shows this.
