It will be more than enough.
Last May I took a Kudu, Gemsbok, Warthog, Zebra, Blesbok, and Impala with a 300 Win shooting 180 gr, partitions. All dropped in their hooves, (actually, the warthog ran about 75 yards in a circle back to where he was shot. tough little piggy)
The only thing you want to take care of is that soft tip of a partition as you will load and unload your rifle 2-3 times a day. This can possibly damage the tip and that may cause you issues if you have a longer range shot planned, especially important if you plan to stalk Kudu.
Interesting.
