I posted this thread knowing very few shooters on this forum build light weight rifles. That being said I appreciate everyone's knowledge and comments. I believe, from what I have read, the blind magazine action is the lightest. It looks like I will build off that action. So I will be looking for a blind magazine long action. I really like the look of mcm edge stock and like the numbers. I think I will do a #2 contour and it will be a 22 or 24 inch barrel. I realize reaching the kimber mtn ascent weight won't happen and that's okay. I just want a much lighter rifle than I have packed to this point. I will keep this thread updated on my progress and will pm if I have further questions, thanks all.
