What would be best of these choices for an expanding bullet in a 9.3x62 for Cape Buffalo?
286g Nosler partition
320g Woodliegh
325g Norma Oryx

Heavy ones running at about 2370fps, 286 running just over 2500fps

So all at Namibia minimum 5400 joules or just a hair over

I have got partitions running great w 1” or less groups, but wondering if one of the “heavy” bullets would better
