I have two rifles on Stillers that are arguably the most accurate rifles I own. They are a 20 Vartarg and a 6.5x47 so they are pretty accurate calibers to begin with. I own several customs on 700's as well. I have a rifle being built right now on another Stiller. I have gone with the last two Stillers because I could get them when I decided to build the rifle. I wanted to try a Borden but wasn't willing to wait for one. For a hunting rifle I would buy another Stiller in a heartbeat and wouldn't worry about it. If I had a 700 in hand I wouldn't hesitate to use it either. I would be more concerned with who was building the rifle.
Get a good smith and ask them what they recommend based on what you want to end up with. He won't recommend parts that won't get you there.
