I have been thinking about a 6mm PPC. All the PPC rifles that I have seen have been on BAT, Farley and Surgeon actions. Being a Savage junkie I thought why not build one on a Savage action. The question is which one? I am not really concerned about a repeater (I guess I don't care one way or the other) so a single shot is OK with me. As the PPC is a Benchrest cartridge, I want this one to be as accurate as possible. I know the 6mm BR has more range but I have my .260 for that so the PPC is what I think I will do.

So here are my questions: First what action? And why?
Second I would use 80gr bullets at the heaviest (most likely bullets in the 60gr range as there are so many good custom Benchrest bullets made in this range) and a 20 to 22" barrel so what twist would I want to use?
Fineally what stock for off the bench, and some prone?
