A 525gr. 50 cal. flat nosed slug at 1,750fps is quite a powerful load. It will certainly do for any & all game in North America and most in Africa and India for that matter. It exceeds any loadings used in the .500 BPE and comes close in bullet weight and velocity for the .577BPE, lacking only bulet diameter which does make a difference. FPE doesn't show this, of course.
