Solitary M
If you' re only intending on hunting whitetails and like the model 70, forget the 30.06 and get yourself a M. 70 Compact Classic in 7mm.08. Devastating cartridge for deer sized game (& b. bear) much flatter than the .06 and less recoil. The little M.70 is a sweetheart to carry, quick to bring up and a pretty good shooter.

As for the 300 H&H, IMHO it' s a cartridge of yesteryear and there is nothing to be gained ballistic wise by acquiring a rifle in that caliber today. UNLESS it' s for the love of an old Classic. I often use my M.70 in 300 H&H (on nice days) for moose but also fully knowing a 30.06 is almost as good and a 300 Win Mag would be better.

I wish the photo did a better job of showing the condition of my old Classic shown here which was manufactured in 1943 and which by the way is all original. gg.
