I am in the process of a new build on rem. 700 action. I am in the process of figuring out what barrel and contour I want? I am going with a 22" tube. I am wanting to keep the gun some what on the light side. I am considering a #5,4 or remington magnum contour. What contour barrel would you think is heavy enough to get the most accuracy out of this caliber? Also what brand barrel would yall lean towards in 7mm? Thanks in advance!
