I agree with Nitro regarding the .308 on buffalo. The shooting in this video is impressive but bears no correlation to sport hunting. My .275 Rigby handles buffalo fine with a good rest and a head shot and so will most rifles. When you are walking around after a trophy its nice to have something with a bit more clout. 308s would hands down have killed more buff up here than anything else and most of the time will be adequate. Its those other times that can really count.
