For illustration-

These petals were recovered from 2 different shots, a bull moose at 170 yards, and a WT buck at about 130 yards. The bullets were both 140gr TTSX from a 7WSM started at 3312 fps. Both bullets exited, but I found these petals in the carcasses. The pair of petals on the right are attached, and weigh 23.3 grains. These came from the moose. The group of 3 petals on the left came from the WT buck, and weigh 24.2 grains. That means that the bullets retained at most, assuming there were no other fragments that went undetected, 82.7 and 83.3% of their weight, respectively. I've seen X/TSX/TTSX bullets lose all 4 petals and end up weighing right around 75% of original weight.

So the bullet hits at high IV, loses some of it's forward mass due to fragmentation, a solid wadcutter shank continues to penetrate and eventually exits the animal. That sounds a lot like PT performance to me. Except with no lead. That ain't a bad place to be.
