I do not think moose is same as eland, kudu or elk. I have shot dozens of moose with 30 cal, 165, 180 or 200 gr partitions and accubonds and all except one stood after the shot and let me shoot again. Of all the elk, kudu and the two eland I have shot NONE did this. One shot and their gone in my circumstances, my eland were hit with 375 300 gr partitions but still ran off.
Yes shot placement is different for antelope over deer. But as already stated all will be dead walking when hit in correct place with any 180, 200 gr well constructed (bonded) 30 bullet.
Love my 308 and 165 accubonds, used on all safaris for PG and just last week for my British Columbia 5x6 elk. For eland maybe step a up in 30 cal power. 300WM, 300 WSM and others in that power level.
