I believe you're best option is an original pre-64 M70 300 H&H in good condition, with an excellent bore. .
A 30-06 can be adapted for 300 H&H. . aside from the chamber, the front of the receiver will need to be notched to allow for extra length and the magazine will need to be changed to H&H or lengthened. . The standard rifle 30-06 barrel is only 24" where the 300 H&H is 26". . This is not your best option as re-sale I doubt will return your investment . . Finding an original 300 H&H is still your best bet. .
Another thought is; stay with a 30-06 as modern loadings come very close to original 300 H&H loadings from years back (1925). The original 30-06 loadings were much lower back in the day but with modern powders and current loadings do very well.
I remember reading an article in the American Rifleman, a few years back, talking about two calibers in two rifles that would do everything he needed in North America . . the 338 WM and 308 Win. . I use both those rifles and find a lot of truth in those words. . I prefer my 300 H&H but could make do. . I like to use my 338 for loading heavier bullets as it'll take a heavier powder charge compared to 300 H&H. .
