I am going to build a 280 AI for my wife for Elk hunting and a 6BR for target shooting. Max weight on the 280AI would like to stay under 6 pds before optics. She wouldn't be shooting more than 600 yards. If I put a short barrel on it for weight an handling will I lose to much velocity for 600 yards? Thinking about 22-24". Needs a adjustable stock or a good adjustable cheek pad. Planning on a Bartlien CF barrel. And also left handed. Not sure what pills I want to put down the tube? For the 6BR again 600 yards is the longest range we have access to. For this one I was going to put the fully adjustable stock on it because there is no weight concern. Probably a Bartlein CF barrel also. Again left handed. Open for suggestions on actions, stock , trigger etc. I would like to see your buy once cry once build sheet. And a more budget friendly build sheet.
