This, is an "easy" one and I already may have the rifle(s) to offer as my solution to the OP's query.
For ME, you may well differ, I would choose TWO to meet this specification.
1. .338WM Alaskan, good synthetic stock, Leupy 1.75x6 MHD and M-8 4x MHD, in Talley QD screwlocks, Brockman rear peep/base and a "Sourdough" front sight. Load ONE bullet weight, using different types if you are "techy" or just shoot 250NPs over RE-22 to make 2800 at the muzzle and with sub-moa accuracy.
2. Fwt.-270Win. all changes as above and scopes are Swaro Z3-3x9, or, Leupy VX3-2.5x8 or Conquest 3x9s. I shoot 150 NPs over RE-22 for hunting and whatever 150s for practice as I do 250 whatevers in the .338s for the same purpose.
I like your way of thinking!!!
