I was hoping a few guys had experience with 224 valkyrie in a gas gun. I have been using Proof Research carbon barrels on my last two bolt gun builds and I have had GREAT luck. I was looking to build a gas gun and was sold on the Proof Research 1-7 twist but a few shooting buddies suggested moving to 1-6.5 twist in a BSF carbon barrels. I was hoping for opinions on the twist and BSF barrel accuracy and quality. I shoot a lot factory Hornady 6.5 Creedmoor and was hoping to start running the 88 grain for this build. Thanks Tom
