Hey all. Decided to turn my old Remmy 700 BDL in 8 mag into a custom 7STW. I figured it only made sense since I have over 400 pieces of remington 8 mag brass I saved over the years. Can the brotherhood answer a few questions for me?? 1. What is the best detachable magazine box system made for the 7STW?? I would like specifics please. 2. What is the optimal barrel twist rate and length for all around use from some of the 140's through the heavy bergers or other vld bullets?? The primary purpose for the gun will be 1,000 yards and closer antelope, deer, and the occasional elk. 3. To brake or not to brake?? Thank you everyone!
