Thanks for all the input guys, I'm zeroing in on a firm blueprint:

Remington 700 short action, .473" bolt face
Badger M5 bottom metal
EGW 20MOA base
Burris Signature 30mm rings
Jewell trigger
McMillan Edge stock, Compact Edge pattern
Barrel contour to be determined
Scope to be determined, though likely a Leupold with M1 adjustments.

Caliber is still up in the air; I lean .308 because of the profusion of good loads, but the 6mm's and 6.5mm's give great ballistics with less recoil and a bit less powder. Decisions, decisions...
