Cowkiller,
I am ready to have MGM make me a 338-8mm Rem Mag barrel because I am not a fan of the Weatherby radial necks and the runout. I was wondering what kind of groups you are getting and what you are shooting if you are a reloader. I may just have to change my mind if you are getting good groups.
My 300 Wby Encore Shilen built by SSK tucks 180's into 1/2" at 100 yds running 3200+ fps.
I can tell you that the integral muzzle brake on that barrel is the most effective brake I have ever used & I think brakes are a necessary evil at best. That said, were I going to the range for a fun shooting session, the 300 Wby gets the nod. Due to its brake it is fun to shoot.
