I have used the TTSXs in 7mm, 270, 30 cal, and the 375 with uniform success at ranges from about thirty yards to right at five hundred. I have recovered only two.
The five hundred yard shot was with a 150-gr TTSX from a 284 Win started at 2900 fps. The deer was hit through the heart on a broadside shot without impacting any ribs. The exit would barely accept my little finger tip.
Though that is an example of one out of maybe twenty, I'll let you draw your own conclusions but I've gone to the 140 in the 284 at about 3100 fps.
I've learned that exit wounds mean very little when it comes to drawing conclusions about bullet expansion and internal tissue destruction. Often mono's will lose some of their petals, and all that exits is the solid bullet shank, which is why you sometimes see a small exit wound, even at high impact velocities. How was the wound cavity?
Sorry Jordan that I didn't see his earlier. I usually am very interested in bullet performamce and almost always try to inspect the bullet path and resultant tissue damage but on that morning it was -25 degrees with a 20 mph breeze and I was underdressed. I'd did not dawdle but the big vessels above the heart were detached and there was a fifth-cent sized hole through the lungs which was probably not bad considering the velocity at that range. A very quick perusal revealed no bullet petals.
