I have been shooting the 168gr TTSX in several 30-06s on bull moose, black and brown bears for a long time. I have yet to recover one and have used many different bullets over the years. For a lot of different reasons from always providing an exit to less ruined meat i am not looking to change bullets.
How fast do you run the TTSX?
I do not get to 2800, but fairly close, using AA3100. I have also used a lot of IMR4831 and also the military 30-06 powder. I forget the actual label name...
