Dear Cosmoline:
I also regard the .375 Holland & Holland Magnum as one of the grandest cartridges ever developed for hunting big game, too. I agree, given good shot placement it'll do the job on virtually all dangerous game animals. However, I just wouldn't be entirely comfortable carrying the .375 H&H Mag. (or the ballistic similar 9,3x64 Brenneke for that matter) when hunting heavy, thick-skinned and big boned animals like elephant, buffalo, rhino or hippo. I am aware that many of these animals have been successfully and humanely killed by the .375 H&H, though, but it's still one of the least powerful, "serious" dangerous game calibers. For hunting the big cats, bears, large antelopes, the .375 is about ideal, I'd believe.
Just my personal opinion.

Dear Dan:
Actually, I thought about including the British .475 N.E. No. 2 into the poll, but then, I'd should have included many other calibers as well, including numerous "wildcats"(like the .450 Ackley you've mentioned). I know, it's not completely fair, but I wanted to stick to the better known rounds.
How effective was your .475 N.E. No. 2 on dangerous game and who's the maker of your double?
I hope, you've enjoyed a successful hunt and that you've also got yourself some fine trophies. I'd be happy if you'd be willing to share your hunting experience here. Thank you in advance.
Many thanks to you all and take care.
