Big game battery? Three guns only? North America only?
Hmmm...
Pre-64 M70 .30-06, standard weight barrel, Warne bases with built-in peep sight and QR rings. Leupold 6x42 with a German #4a reticle.
Pre-64 M70 .375H&H, ditto above.
Pre-64 M70 .25-06, ditto above.
Of course, it could all be done with the .30-06 alone. And, the .25-06 can do all but the heaviest lifting (big bears, etc.) easily; and the .375H&H can do all but the longest range stuff easily. Which is kinda the point on these picks; overlap, redundancy, familiarity of ballistics, etc.
They ain't flashy, but they'll work, ammo is available everywhere, and they all back one another up quite well.
