I have a custom 300WSM built off of a M70 action. It will likely be. 3 contour SS barrel with a side port break to keep the build a little more budget minded. The 3 calibers I'm probably considering are 300PRC, 270WSM, and 6.5PRC. I'm leaning 6.5 bc I don't own a rifle in a 6.5 right now but I'm open to ideas. Thoughts??
