Chip--
Thanks for the additional background.
Go buy the 6.5-06 that is for sale right now in the classifieds; sounds very much like what you have in mind, for about 70% the cost of building it yourself.
Another approach would be to get a matching Weatherby in 257 Roy, since you already like that action.
Stanimal's blueprint is about a perfect version of the campfire preferences. Given that you want light weight and accuracy, Remington actions are the place to start, IMHO.
