I fired a few rounds from my 475 FA Linebaugh into some elephant skulls, both bull and cow on my last Safari.
All shots reached the brain. Load used was Buffalo Bore 420 LFN. However the 475 does not penetrate as good as 450 North Fork FP or 480 Woodleigh Solids from my 450 No2, nor as good as 286 gr Woodleigh Solids from my 9,3x74R.
