Re: Case Weight vs Case Concentricity?
Well, let's see:: I have developed a 308 loading that shoots 0.35" groups at 100 yards and I have never sorted cases (other than by lot) either by weight or by concentricity.
I have measured concentricity of the composnets used in my reloading process, but in general, its good enough that I don't do any sorting based on concentricity (Except for tossing seriously bad loads into the foulers pile.)
