I didn't know this was a discussion comparing handgun cartridges vs rifle cartridges killing capacities. Obvious difference for most rounds. Animals? Man is often a much more softer target than most animals. In any case, a handgun is a handgun and has a handgun's limitations.

Of course if hunting, a handgun has its limitations. But no different from there being limitations to using BP, a bow, a shotgun etc.

This is a discussion on a handgun, used from the late 1800's to the 1950's in countless countries, many wars and during the peak of the British Empire.

Interestingly the .455 Webley probably had some of its origins for the same reasons as the excellent and powerful .45 ACP. As probably everyone knows the .45 ACP was created at least in "popular" history as the US .38 revolver service round had trouble dropping crazed Philippino rebels or warriors. Anyone want to discuss this, it would be a great topic for a NEW thread, on the .45 ACP and its origins. In handgun discussions most Americans discuss the merits of the old .45 ACP compared to say the much weaker 9mm Parabellum. The .455 Webley probably saw use it dropping crazed Zulus (though not in the Zulu wars which were slightly earlier), Matabeles, Somalis, Mau Maus, Malays, and other races of very angry people.
