I'm in the process of mapping out my hunting rifle build. Using a trued 700 action and probably Manners new T6 or their new hunting style that I've heard rumors of, either one with the lightweight fill. Barrel contour is where I'm stuck. It will be in 6.5x47Lapua and I want to have it around 20" and use my Tbac 30p-1. What is the lightest contour I should go with and still have good enough shoulder for the can to mate up with?
