I’m new. Really new to F-Class Open. I’m asking for your help. I want to build the following: .284, Cerus stock, BAT Action, Brux barrel, Jewel trigger. What I need help with; which BAT action, M or 3LL? What length barrel? What twist? Barrel taper and or fluting? I’m certain these questions are rudimentary... I really appreciate your help! Thanks!
