Well I am planning a build with my 111. I have a sharp shooter supply trigger savage 110ba rail 6-24 vortex. I am looking at getting a mcrees precision stock and a longer barrel. I am wanting a over 600 yard hunting/target rifle.now this dosnt meen I will hunt 600+. What would u suggest for barrel length and contour. Are there any mods I could do to the action to help with accuracy?
