My son has used the 80gr TTSX on the largest bodied bull moose I have ever dealt with... and there have been a huge number of them. Caribou, a brown bear, multiple black bears, Sitka deer, a mountain goat... A total of three bullets recovered. One penetrated a huge elbow and half of the other... with some sternum between. Another went through a bedded Sitka buck and tangled in the hair after bouncing off the rock behind. I forget what happened with the third... if it happened.
