When the 224 Valkyrie was the new hot thing, I acquired a Remington 700 6.8 SPC action and screwed on a pre-fit barrel. After several years with the gun, the accuracy just doesn't impress me. I'm considering having the bolt opened to accept the new ARC or Grendel brass, but I'm curious if I'd be better off selling the action and just getting a new action set up for the PPC bolt face from the start?
