There always is a repeated thread about bullet performance and discussions are often conducted in parallel in a number of threads as there is no section dedicated to bullets - that one item which is what firearms are about.
Personally, since the advent of the flat nose monolithic copper solid bullets in South Africa which create a 4x calibre wound channel and zero meat damage no matter the impact velocity from a rifle, or shot placement, or type animal I find no more reason to use expanding bullets at all. In my personal experience with various calibres and with game like Cape buffalo, kudu, sable, waterbuck, bushbuck and even the dimunitive duiker the flat nose solid has replaced even the best controlled expanding designs and I am slowly changing completely to the Peregrine VRG-2 monolithic copper solids for all my rifles.
