Personally I’d lean toward the TTSX over the TSX. It’s supposed to expand at a little lower velocities, which could buy your a few extra yards to work with! It’s difficult to beat Barnes mono bullets on big game! Good Luck with whatever you choose! memtb
After randomly asking about a specific bullet, I ALWAYS email Barnes about new rifles/loads. Here is the reply about their .358 offerings. MANY of their bullets have different design windows. I have been quoted anywhere from 1500 FPS (168 TTSX .308) up to 2000 FPS for the min opening velocity depending on the bullet in reference.

The 180 will open down to 1900 fps, the 200 gr. will open down to 1800 fps and the 225 will open down to 1600 fps.
