When you shoot that puppy, take care that the front swivwl mount doesn't wreck your off hand.
I had to remove the forend swivel mount from mine, and install a barrel ring mount QD stud - filling the resultant forend hole with an inlaid cartridge/case head.
My $0.02, though, IMHO you're over-scoping it, with the variable.
In my experience, if you must use a scope, eyesight and aiming does best with a bright, low-powered 2 1/2X or 3X - and I would only put a Leupold ($270) on a .375H&H.

It's nowhere near as heavy as a Ruger .375H&H or a Model 70 .458, though.
