OK, here's what I would do:
Remington 700 ADL 300 Win Mag: $369
Pac-Nor SS Select Match: $240
Pac-Nor Fir Barrel & True Action/Lap Lugs: $250
Pac-Nor Barrel Fluting: $100
McMillan A-5 Stock: $425
This leaves a little cash to buy some accraglass or whatever your favorite bedding compound is, and shipping, FFL transfers etc. Without a doubt, this rifle would be superbly accurate.
