1. I have observed that the majority of custom rifles are built on the Remington action, why? What's wrong with Ruger, Winchester, or Weatherby? Back in the 80's, Sakko was the optimum action for custom guns. 2. I have a rifle that I want some custimization done to, where do I start? Obviously I can't say I want the least expensive...EVERYONE wants it done cheap. From all I read, the first thing to do (besides the basics like floating and trigger work) would be to change the barrel out. True?I live in Mesa, AZ. 3. How much does it take to change the .338 WM to an Edge or Lapua? Arrrgggghhhh...so many questions and the internet isn't showing me what I want! I live in Mesa, AZ and I know there HAS to be some good gunsmiths around here I can talk to.
