The partition is never a bad choice. The LRX has a better BC but way out there I think a partition would open up better, A good compromise might be the LRAB I have had good results for closer shots with them and I am sure they would do well at extended ranges within their velocity threshold.
The Nosler LRAB will hold up, but I have never used them in anything bigger than the Swede so caveat emptor. I would go LRX or LRAB depending on which shot better in your rifle. The LRAB I would say opens better at lower velocities than the partitions and possibly the LRX and retains close to the same amount of weight as a partition but I can not say from personal experience as all of them have blown on through.
The 129s have worked so well that I haven't gotten around to trying the 140s, this again in the Swede. You will not be disappointed with any of these, but for me LRAB is it.
