All of my Model 700's have shot good out of the box. The 300 RUM I think I went a bit overboard with. The 338 RUM had done at a local gunsmith with just the accurizing package and brake. The 7mm RUM SA had nothing done except trigger work. They all shot just the same.
I will say however that the 7mm had to be returned to the factory for a new barrel as when we had it at the gunsmiths he showed me missing rifling in the barrel.
