Those eland are big big animals, think Brama bull size. While the 260 grain partition will work fine if a good angle is taken, the 300grain partition would work better. I took mine with a 300gr A-frame out of my 375. With that said, I would suggest you use 300gr accubond or 300gr A-frame which are both bonded bullets unike the partition which will shed the front part on entry. Your PH is not gonna let you take shots over 200yds and more than likly will get you within a 100yds. He doesn't want to track a wounded one for 2 days so use biggest bullet you can and don't stop shooting after the first one. The 4 skined hanging Qtrs on mine weighed 900lbs. Good luck on a great animal
