As a reference for others. Here are the Barnes part numbers and minimum terminal velocity requirements. They usually say to add 100-200 fps to these numbers for reliable performance.
The 150gn TTSX is more stoutly made (for higher power 30 cals) and requires 2000 fps. They did say they were considering a new offering of a 150gn with lower velocity requirements.
30345 (130gn tsx) = 1800
30347 (150gn tsx) = 1800
30349 (165gn tsx) = 1800
30364 (130gn ttsx) = 1800
30318 (175gn LRX) = 1500
A few with lower fps
30321 (110 gr TacTx) = 1400
30320 (120 gr TacTx) = 1350
30820 (150 gr 30-30) = 1500
30351 (168 gr TSX) = 1500
30370 (168 gr TTSX) = 1500
