I have never hunted outside North America.
However, in the late '60s /early '70s, when we lived in Canada's Northwest Territories, it became possible for residents to hunt completely-wild Wood Bison just by buying over-the-counter tags.... no draw, pay $25 and go hunting.
These animals can be enormous, being somewhat larger (and darker in color) than their plains-bison relatives. The biggest bull I ever killed yielded 1700 pounds of MEAT IN THE FREEZER.... meaning a live weight of around 3000 pounds. His hide spanned our 12-wide "house" of those days, from up-one-wall to up-the -other-wall. The horns span 30"....I'm looking at them as I write.
Anyway, we quickly found that our normal "moose rifles" were less than great at quick kills on these heavy-woodland bison, and a wounded animal could easily vanish into thousands of square miles of dense bush. So.... I wanted something to put them down NOW, not later.
I found a Cogswell and Harrison Mauser in .404 Jeffery on the used rack of an Edmonton gunshop. After teaching myself to load with Berdan primers, I had excellent success with the 400-grain Barnes Original .404 bullets, killing about a dozen of the bison over the years we hunted them.
My last bison hunt was in 1996, by which time only fifteen tags were available to residents on a draw basis, and the hunt was held in a different area as well. That was the first time I hunted with my then-new Ruger #1 in .416 Rigby, but I was not successful in bagging a critter.
However, these events sparked a deep interest in larger calibers which persists to this day. Since emigrating to Nevada in '97, the larger rifles have become entertaining test beds for cast bullets, and they perform superbly with cast lead. I've fired TEN-shot .416 groups under 1" from 100 yards with only a 4X scope, and the .404 is pushing that performance pretty hard as well. (My Hoch bullet mould for the .50BMG drops a bullet weighing 888 grains with my wheelweight alloy. THAT is a serious bullet!)
There is a place for the big rifles, even if their utility is somewhat specialized. I'm sure glad I had my chances at "big animals and big guns". I also carried my .50-2.5 Shiloh on a moose hunt, once upon a time.... never got a shot on that occasion.
