Looking for a 1-8 twist for a build? Want to build either a 6XC, CM, or a 243. I would prefer a lighter barrel like a # 4 contour, I want this for longer range coyotes, Long range for me is 300- 600 yards. Thought about just buying a Bergara Pro in 6 CM, but I have a nice Stiller acton sitting in the safe.
