I have done them both ways and came out well, , using Shaws and once a takeoff .338WM that I put on my hunting pard's 7 Mag when it went belly up. His shoots almost as well as mine, and mine is MOA or better with fire-formed, neck sized hand loads. Original barrel.
As said above, Shaws are a good value.
