Not sure I believe 14 .220 Swift hits on a hyena who still needed a finishing shot. Bell used the .220 Swift on deer but he favored neck shots and he did say the cartridge lacked penetration for other shots. I’m sure Ruark was using the early 48 gr factory loads. There are better bullets available today but I don’t know that any of them would turn the Swift into an hyena killer.
I can attest to the effectiveness of neck shots on American mule deer. Definitely a very humane shot as it is instant lights out.
Remember Ruark's caveat about his own shooting ability. Somewhere (I can't remember where) he says he was a shotgun man, southern quail shooter, and his riflery skill was less than stellar/poor.
