If it were me, and this IS a trip of a lifetime, (maybe, for me anyway) I'd go to the range and try all those and a few more probably.
I have used the Nosler line of bullets for over thirty years, handloading them for twenty, and they work well on critters, when they areplaced accurately.
Try that 180 grn Partition, as well as the Accubond, they're dependable, and deadly when accurately placed shots are the norm.
