My first question, besides why the 375 H&H over the 9.3x62, would be what are the dimensions of the bottom metal you added?
A 9.3x62 would be the easiest, a .375 Ruger would be a little more difficult as you would have to open up the bolt face and extractor and possibly open the feed rails, and the 375 H&H would require opening the bolt face and extractor, a longer box, opening the rails and removing some feed ramp and bolt stop and ejector.
None of it is terribly difficult for someone who has experience.

Anyone who claims the 30-06 is not effective has either not used one, or else is unwittingly commenting on their marksmanship.
