You have not listed a bad choice. 140gr AB, 110gr TTSX, 130gr TTSX.
Have not used a LRX, but cannot imagine it not doing the job, IF you do yours.
If you feel like playing with a new bullet, go ahead. Truly spliting hairs.
I/we have killed critters with 85gr TSX through 160gr NP.
It is more difficult to find a bullet that will not work in a 270 than one that will.
