At this point I feel compelled to repeat the comment from the most experienced African PH I know, who retired a few years ago. He was born and raised in what was then Rhodesia, and killed his first buffalo at 17, when he started working as a game ranger for the parks department. Among other things, he was one of the original Selous Scouts during the revolution that turned the country into Zimbabwe, and also a culler for a huge ranch, where he killed hundreds of buffalo, mostly during drives.
When I met him, his total time as a PH (between short stints at other jobs, including a couple years working for the U.S in the sandbox) was well over 30 years. He used several cartridges for backing-up buffalo hunters, from the .375 H&H to .458 Lott, and when I asked him what .375 bullet he preferred, said: "Whatever clients leave behind. These days all the bullets are good!"
