My thoughts are the TTSX performed as it was designed to. And that is to drill deep. The way they drill deep is by being more stoutly constructed than cup/core bullets and hence retaining near 100% of their weight. And consequently you get a smaller diameter wound channel. I can't think of a better bullet when the muzzle velocity exceeds 3000 fps and or when you are hunting large game and need deep penetration.
But for smaller large game, I'd say a cup core bullet or dropping to a 130 gr TTSX would be a better choice. YMMV
If the impact velocity gets much above 3000 fps the petals shear off and the wound channel volume is even smaller. I know this goes against the Campfire mantra of "mo speed,mo betta", but it's what I have noticed in using them.
Best advice I can give is keep impact velocity between 3000fps on the high end and 2000fps on the low.
