I am wanting to build an F-Class comp gun in 6.5x47 Lapua. I think I want to go with a 29" strait taper. My first question is, which action to use. I have narrowed it down to three actions, Stiller Predator V action, Bat model b or Borden rimrock. Will the extra price in the Bat be worth it? Or should the Borden be just as good?
