Thank you sir. Valuable info. I am not clear whether yo have to turn down the necks afther sizing down the 6mm.22BR Build
Had my trusted smith (Mark Chesebro) spin up a barrel chambered in 22BR with .255 neck and .100 freebore for the Berger 85.5 grain hybrid. Wanted something with great accuracy and minimal recoil for shooting club and local PRS style matches. Finally got some time to get some rounds down range...forum.accurateshooter.com
