Re: Building a new rig...
You may want to look into a different brake. I have a Vias on a 300WM and it helps with felt recoil but that rifle jumps all over and makes one hell of a dust cloud when shooting prone. I would look into a brake that reduces felt recoil and also helps muzzle rise. I have not shot one yet but I am putting a defensive edge on my new 300WM and 338 Lapua.
