I'm wanting to build a 6.5x47 Lapua. I already have a Remington 700 S/A to start with. I would like a Manners T or TA stock with the color molded in it. I also have a MARK 4 Leupold 6.5-20X50 to go on it. I guess I would really like to know who's barrel, twist, contour, and length would be the best fit???? I plan on shooting 130 Bergers in it.
