Soft bullets caused the bad vintage reputation not its ballistics of the 10.75x68.

All those "modern choices", who cares about them? Especially here on NE. Let the newbie on his first and one only ever cape buffalo safari, before selling the rifle when he gets home again, choose all those. "new fangled modern creations".

By your logic, no one would use a 9.3x74R, a 9.3x62, a .318 WR. a .360. and .338, a 8x68S, and numerous other choices which killed excellently a hundred years ago and still kill as well today.

Lesser powered choices always need to have this consideration in mind when taking a shot.

I think using vintage rifles with vintage cartridge chamberings is a joy and an experience to treasure.

A friend used his "new" (to him) Mannlicher-Schoenauer 6.5x54mm to shoot two big water buffalo bulls well. He choose his shots carefully.

A ".900 Whopper" is not needed for everything or even anytime.

But everyone to their own choices.

But again thanks for your comments on your experience with the 10.75x68.
