I am planning to take safari number 2 in 2020 and starting the planning, because hey, why not. A few animals that are on my list include Nyala, Zebra, Blue Wildebeast, Giraffe, and Eland. I took a .300 win mag on my last hunt and 200 grain partitions did great on Kudu, Gemsbuck, and Waterbuck. The Black Wildebeast I took 3 bullets before he went down, even though the first broke his shoulder. Those things just don't want to die. The only animal on my list above that gives me pause on if I have enough gun is giraffe. What is the general consensus on giraffe caliber? Do some outfitters require larger calibers?
