I am in the process of building a 6.5 Creedmoor, I have just about everything decided on except the barrel. My plan is to shoot 130gr and under as there are several bullets in the .550 to .571 BC range. My 1st question is should I go with a 9 or 8 twist barrel? This gun will be used for everything from long range yotes, hogs, silhouettes to possibly getting into some F-Class.

2nd question is barrel choice, I have used pretty much only Pac-Nor with great results. I am trying to decide if I should go with them or try one of the following barrel makers for this build. I was thinking these below, or should I just stick with what has been working?
