Browning Action/BBL's

They are very good, my most accurate out of the box rifles have been Brownings. No experience with X-Bolt, but I've heard it has very good accuracy and I like the detachable mag. The main issue for long range is lack of aftermarket support for stocks/chassis and mags. I'm planning my first long range build, but after a LOT of research and deliberation the practicalities with the cartridge I want to shoot pretty much require a Remington 700 to get what I want (requires a long action, and I want a detachable mag).
