Stillers rock. I just built an 22-250 AI on a stiller tac 30 with stiller DBM. Check out Southern Precision Rifles :: Bugholes.com he has stillers and barrels in stock. Can be fitted up by Harold Fredd if so desired.
I too am planning a new rifle build. As far as actions are concerned I am between a Stiller Tactical 300, a Defiance Rebel action or the Surgeon 591 action. They are all amazing and it makes it very hard to choose. As far as Stiller vs Remington action. The Remington can't compare.
