I'd look at a more classic scope for that there 375h&h. Maybe a Leupold 1.5x5 or a tasco titain 1.25-4.5. Something with a straight tube up front. That's what a classy safari style hunter needs.

The other thing is have you considered the steel 1 inch QR rigns from weaver, they work real well and you can take them off and try and get those iron sights figured out.

Having the QR feature is a handy little advantage when the chips are down.
