I agree with the 150 being too light, I also like the heavier bullet, but then I do I explain this
to my brother. He used it now on kudu, blesbuck and this hartebeest.
All one shot kills, and except for the bullet on one kudu all other bullets exited.
He hunts in more open areas and wanted the slightly less drop
of the faster bullet. I presume the 150gr's still have enough momentum
to do the job.
