I love TB, but be careful with it because man it can get spooky. I was shooting 125 gn and 150gn SSTs from a 30-06 with TB, same starting charge behind each bullet and the 150gn shot 450 FPS faster.
I still have the ammo box sheet and notes from that session, I keep trying to convince myself that I got the 125s and 150s mixed up but I loaded more of one than the other and all the other loads shot as expected. That was a very not-gentle reminder about keeping one set of components out at a time, nothing centers the mind quite like touching off a 30-06 expecting a gentle puff but getting a decent bang out of it.
