A high shoulder will drop game in a heap, but the TTSX is far from the only bullet that will do that.
IME&O the various X iterations are far more reliable at producing an exit and do far, far less meat damage.I will not use a C&C bullet on the shoulder of a meat animal...
Personally, I don't care about meat damage. However, animals are in general sort of way made out of meat and meat-like substances. Since animals are killed by damage to the most immediately necessary bits, it stands to reason that that whatever does the most damage kills the fastest.
