You don't want "versatility" on a dangerous game rifle. You want a rifle that's optimized for dangerous game and above all, will absolutely, positively work every single time.
I don't see the point of all the gimcracks in the reticle. Do you really need vertical range marks on a 4x scope? If you must scope a DG rifle, you want a fixed power, not only because they are physically more robust but because they can't get set to 4x when you desperately need to get a sight picture right now.
I'd recommend ghost ring sights, but if you must have a scope, try a fixed 1.5x, if you can find one or a 2.5x scout scope.
